Overview

The K522 hydrogen purity analyzer is a "non display" instrument. The standard configuration of K522 consists of electronic modules, sensors, sample chambers, and increased safety junction boxes. This instrument provides 4-20mA output and RS232 communication. Various configuration parameters of the K522 OEM analyzer, such as detection gas, background gas, detection range, analog output, etc., can be set through software. Calibration and real-time readings of the process can also be recorded through software.

Product Details

Hitech Instruments Co., LtdK522 Hydrogen Purity AnalyzerUse thermal conductivity sensors to accurately detect changes in a specific component in binary or quasi binary gas mixtures (i.e., where only one component changes in the mixture). itsThe sensor has a high sensitivity, low heat capacity, and non consumable component that requires no maintenance and has a long lifespan.

Requirements for sample gas

The standard configuration of this instrument does not include a sampling system and a sampling chamber. The sample gas must not agglomerate and will not cause corrosion when passing parallel to the sensor sintering surface (i.e. not directly facing the sintering surface).

Sensor: Stainless steel thermal conductivity meter sealed with air reference gas

Gas detection and its range: 0-5% hydrogen in nitrogen or argon or hydrogen in oxygen, 0-10% hydrogen in nitrogen or argon or hydrogen in oxygen, 0-30% hydrogen in nitrogen or argon or hydrogen in oxygen, 0-100% hydrogen in nitrogen or argon or hydrogen in oxygen, 95-100% hydrogen in nitrogen or argon or hydrogen in oxygen, 0-100% helium in nitrogen or helium in argon or hydrogen in oxygen, 75-100% nitrogen or hydrogen in oxygen, and 0-100% nitrogen in nitrous oxide.Other ranges and gases can also be used. Please consult customer service.
