PRO-CHEM ANALYTIK H2Trans4 - 20 mA Loop Powered two wire Hydrogen Transmitter Two Wire Process Hydrogenanalyzer The Model H2Trans is simple, accurate and economic measurement of Hydrogen at trace and % levels. A simple Display and one point calibration allow easy and fast start-up of the instrument. The unit will offer with ranges between 100 ppm - 1% of hydrogen. The H2Trans uses a special fuel cell to measure the hydrogen concentration. The sensor meets the industrial requirements for accuracy, sensitivity, easy to use and operating life. The calibration of the instrument for trace hydrogen measurements in gas, should be done with a calibration gas. The concentration can be chosen freely within the measuring range. In the percent range the unit can calibrated with air. ✓ Sensor with long operating life ✓ reverse voltage protection and temperature compensation © Flow-through measuring cell in Stainless Steel • The measuring cell is modular and is made of stainless steel • A defective measuring cell can be repaired by replacing the defective part only, rather than the complete unit
