«The working principle of the instrument is the static volumetric method of isothermal physical adsorption. It is used for accurate analysis of pore size and specific surface area indicators.It is a truly fully automatic instrument.The instrument panel does not have any manual buttons, and all operating procedures are controlled by the computer.
«High-precision twelve-in-one solenoid valve control module provides protection for the permanent sealing of the gas circuit. This module is produced for high-precision CNC machining centers and is the first in China.
«Both the adsorption and desorption process are automatic and can reach hundreds of analysis points; the detection accuracy of the imported high-quality pressure test system reaches ± 0.15% Of Readding.
«A network server that is open 24 hours a day, 7 days a day enables the remote control function of the instrument to be applied, allowing users to understand the test status anytime, anywhere.
«The instrument is equipped with a liquid nitrogen liquid level holding device to ensure a constant temperature throughout the analysis.
«Safe and reliable air pollution prevention measures to ensure that the instrument runs for a long time without failure.
«Po's independent sensor and automatic measurement function provide guarantee for the accuracy of data.
«Each analysis station is equipped with an independent sensor to ensure the simultaneous analysis of the three analysis stations.
«Vacuum analysis station, leak detection, pressure sensor linearization and P0 determination are automatically performed at the same time. Quick analysis after power-on is initialized to start of analysis, which saves 30 minutes compared to conventional.
«Equipped with a 4 liter large-capacity Dewar flask, combined with a patented liquid nitrogen isothermal clamp, to ensure at least 48 hours of unattended operation.
«High-level software engineers provide powerful software support for SSA-4000 series instruments.
