The purchase of weighing (electronic balance) products involves an overall comparison of range and cost performance. This article introduces some of the main points to consider when purchasing a weighing instrument (electronic balance).
When buying a weighing instrument (electronic balance), there are several important criteria that can help you find the product that suits your needs. Usually the price is considered to be the decision point, but in order to obtain the maximum utility of the scale, you should consider the total value the scale brings to your operation. If a weighing instrument is a key issue for your business efficiency and profitability, especially if the weighing instrument is used to manufacture or package products, a low-cost weighing instrument may cause more expensive losses in the long run.
One: range
The main criterion is the total weight of the object you want to weigh. A common mistake is to buy a weighing instrument (electronic balance) with a maximum range that is the same as the weight you usually weigh. Although this may seem to be the right choice to help you buy a cheaper weighing instrument. Be sure to remember a few technical specifications regarding the maximum range of the scale (electronic balance). A scale is rated at 100 pounds. How much additional weight will be added without damaging the scale? Ohaus products usually provide a 150% overload rating, so that a 100 kg scale can handle a load of 150 kg. After this load is exceeded May damage the weighing equipment. More importantly, how to increase the weight on the scale? Some operations habitually throw items or bags on the scale, which increases the force (also called dynamic load) that the scale bears. Therefore, the same 100-kilometer scale can normally handle a 90-kilogram load. If the same load falls from a height of 5 feet, the scale may be damaged. The way to ensure that the scale can bear the load is to buy the scale with a maximum range that is twice the weight of the object you want to weigh. Therefore, a 100-kilometer scale is best to handle a 50-kg load instead of a 60-kg scale. A scale with a larger range may initially cost more, but it is more suitable for your business needs.
Two: weighing unit
Another question to consider is which weighing unit does your operation use? Pounds, kilograms or ounces? Depending on your weighing object, the weighing unit used is also different:
Changheng system-pounds, ounces, tons, klins, etc.
Metric-kilograms, grams, milligrams, metric tons
Jewelry-Kling, Bennett (dwt), ounce (ozt), carat (ct), etc.
Custom weighing unit
In some cases, the weighing unit will be determined by legal regulations, while others will depend on your operational needs. Do you need to change the weighing unit quickly, or do you only need to use one weighing unit? When buying a weighing instrument (electronic balance), it is very important to make sure that you understand the problem and buy a weighing instrument that is suitable for your operation.
Three: readability
Another major factor is the readability of the scale (electronic balance), or how accurate the scale is. The readability of the scale is often confused with the precision of the scale (the precision of the scale is the specific combination of the scale, the way the scale is set up, the way the scale is used, and the maintenance of the scale). Many large scale scales only require a readability of 0.1 grams, and the platform scales used in QA / QC (quality assurance / quality control) on production lines may have to require an accuracy of 1 gram.
The inherent requirement of this question is how reliable the weight reading must be, which may be regulated by law and affected by the object being weighed. The general rule of thumb is that the accuracy of the purchased weighing instrument (electronic balance) is ten times the accuracy you need (for example, if you need a readability of 1 gram, purchase a weighing instrument with a readability of 0.1 g), or the installation is approved / Certified weighing instrument.
If the weighing process is legally approved or certified, the scale must comply with the legal standards for the reliability level of the scale's readability. Even if your operation does not have this legal requirement, the use of approved / certified weighing instruments will ensure a higher level of performance.
Four: the size, shape and movement of the object
The objects weighed on most weighing instruments (electronic balances) do not need special consideration, but your process may require additional functions of the weighing instrument for accurate weighing. Is the size of the object too large, such as a transport box, covering the display? Is the object moving, such as livestock, or is the environment moving the object, such as a conveyor belt? Is the object round and requires you to box the product? Understanding exactly what the weighed object is is a key consideration.
Five: Mode / Software
After you have determined the range and the required readability, the next step is to decide what mode or software is needed for the weighing instrument (electronic balance) suitable for your application. Most scales are used for direct weighing and may have some additional filtering functions to reduce environmental issues such as vibration. The most common weighing applications are:
Parts counting
Check weighing
Percentage weighing
Dynamic weighing
Show hold
Data accumulation / summation
Statistics output
Retail price calculation
In line with trade
Traceability of GMP or GLP
When purchasing a weighing instrument (electronic balance), decide whether the weighing instrument has more than one application and ensure that the actual working method of the weighing instrument (electronic balance) is suitable for your operation. Many weighing instruments (electronic balances) provide part counting, for example, but each weighing instrument (electronic balance) operates on a different principle and may provide software to improve the accuracy of your piece counting. All these factors will affect the accuracy of your piece counting in daily business operations Sex. When you buy a weighing instrument, your local dealer can help you choose the weighing instrument that suits your application and help you set up the weighing instrument appropriately.
Six: Environment
Another problem is the overall environment in which you use the weighing instrument (electronic balance). Almost all weighing instruments (electronic balances) operate normally in a laboratory environment, but weighing instruments (electronic balances) also have certain characteristics that can be used in harsh industrial environments or outdoors. The general technical specifications of industrial scales are NEMA or IP grade, which tells you that the scale can resist the performance of handling dust, dirt, water and other materials that enter the scale. Above this level, scales with IP65 or NEMA4 or higher can be cleaned and resist the penetration of dust and water.
In addition to waterproofing, scales used in food processing and catering services require additional approval or certification. NSF (National Science Foundation) provides numerous food safety standards and provides approval / certification for catering equipment. Moreover, the scale can also be approved for food processing applications through the USDA-AMS, often requiring equipment to support the HACCP food safety system. Knowing which food safety standards are applied is critical to ensure that you have the right weighing instrument for your operation.
Seven: temperature
Another environmental factor is the temperature range, which is very important, because the materials used in the production of weighing probes in scales (electronic balances) may be affected by the ambient temperature, as well as by the rapid changes in temperature.
In addition to ensuring that the scale (electronic balance) and the ambient temperature are kept equal, most applications do not need special considerations, but if your scale will be used in harsh environments, please consult your local dealer to ensure that you buy a scale suitable for the specific application .
Eight: Connectivity
Many situations require connectivity to computer systems and printers, which can provide traceability and process control. Most provide RS232 ports for connection to printers or computers, but many weighing instruments (electronic balances) are equipped with USB, RS485 / 422 or other standard options. If your application requires connectivity or printing, choose the right weighing instrument. Usually your local distributor can integrate the weighing instrument (electronic balance) into your production process, or as a consultant to help you get the maximum benefit from the investment in weighing instrument.
Nine: after-sales service support
As with any other device, quality assurance requires understanding how much quality assurance the manufacturer provides for their products. Most manufacturers will provide a certain period of quality guarantee for their product design defects or manufacturing defects, although these problems will appear relatively early in the purchase period. Some manufacturers provide long-term quality guarantees, and some provide short-term quality guarantees, but in most cases the quality guarantee does not include damage caused by improper use and accidents, or normal wear and tear.
As important as quality assurance is the technical support provided by the manufacturer. Is information available online for easy reference? Can you quickly download a new manual? Is there any additional information on how to use the product, such as quick start guide? Is there dedicated technical support to contact you by phone or online chat?
Equally important is how much support you need from your dealer. Do you need a dealer to help you set up the scale and calibrate the scale to get the best accuracy? Can they help you integrate the scale into the production process? Can they provide regular calibration? Can dealers easily obtain repair parts? Distribution Is the dealer an authorized dealer, or are they reselling the products they bought through another dealer?
in conclusion
There are many factors to consider when purchasing (electronic balances), especially if your business depends on weighing instruments to achieve profitability (electronic balances). As with any device, the value of the product, not the price, will determine whether it is a good investment. Please be sure to carefully consider your needs and the capabilities of the scale, you will be able to make the right choice.
