Overview
The HZ-400DJEx gas moisture analyzer is a moisture analyzer independently developed by our company. The system consists of a separate instrument unit and a pretreatment unit. The testing system uses P2O5 electrolysis to measure the trace moisture content in the gas. As long as the gas does not contain components that damage the pentoxide coating and cell body, do not undergo polymerization reactions on the electrode, and do not participate in electrolysis reactions, it is suitable for this instrument.

4HZ-400DJEx gas moisture analyzerTesting principle:
Electrolysis method test, the electrode absorbs gas moisture, electrolyzes into H2 and O2, and the amount of water molecules can be determined from the consumed current. The electrode is a washable P2O5 electrode, mainly made of a glass rod as the substrate, wrapped with equidistant platinum wire on the substrate, and then installed with a detachable corrosion-resistant material body.
This principle is applicable to various working conditions containing corrosive gases, such as CL2/HCL/H2S/HF, etc.
Note:
If there is a liquid component in the medium, this method cannot be tested
This electrode is also suitable for combustible gases such as CH4 and other inert gases
This electrode is not suitable for gases such as NH3 and other gases that react with H3PO4
5. On site working conditions:
A, pressure
The on-site pressure is about 6 kilograms, which can be adjusted by reducing pressure
B, temperature
The maximum temperature on site is approximately 160 ° C, which can be lowered to below 50 ° C through a spiral tube
C, component
There are corrosive gases such as hydrogen chloride in the measured medium on site, and electrolysis can avoid corrosive interference
D, moisture content
The on-site moisture content is approximately 0-100ppm, and after cooling treatment, the impact on moisture concentration is very small
E, protection
The equipment adopts a flameproof structure
F, Special Ingredients
If there is a liquid substance component in the measured medium, this method of measurement is not supported
