Segmented pressure sensor configuration, saturated vapor pressure at room temperature for a lower class steam adsorption test qualitative analysis, achieve higher accuracy;

Break pressure measurement

According to the characteristics of vapor adsorption, with a low temperature of liquid nitrogen cold trap, which can effectively prevent steam from entering the vacuum pump oil pollution;
Cold trap can effectively capture high-boiling adsorbate, it is an essential means of vapor adsorption analysis;

Cold trap

Using the most advanced adsorption process vacuum static pure steam, without a carrier gas, no gas flow, the carrier gas is relatively dynamic way to carry the weight of the weighing accuracy higher vapor adsorption;

Static adsorption process

The instrument has the most advanced international automatic distillation purification system, a high-purity adsorption steam source, provide the basis for high-precision test;

Distillation purification system

For vapor adsorption, PW-type instrument equipped with full thermostat, that test site adsorption chamber sample tube and the reference cavity manifold module, valve group so the whole gas line, be closed thermostat, full adsorption system no cold spots; and the use of high vacuum gas control valves, solenoid valves without fever phenomenon, to further improve the system temperature effect; constant temperature range: room temperature to 60 ℃.

Full thermostat

Instruments microbalance with automatic calibration function may be performed before each test automatic calibration operation, to ensure test accuracy, eliminating artificial calibration;

control

Original modular air system, control valves overall integrated design, the leak point reduction to the limit, with 316L stainless steel high vacuum air control valve, the entire system leakage rate of less than 10-8torr * m3 / s, improved sealing more than five times, reaching the level of imports of high-end equipment, greatly enhance the stability and accuracy of the instrument; the various parts of the gas system integrated modular assembly, which greatly reduce the failure rate, significantly enhance the stability of the instrument。
