RD-400 thermal conductivity hydrogen analyzer

Brief introduction:

RD - 400 thermal conductivity type hydrogen analyzer based on gas thermal conductivity difference principle of work, by the thermal conductivity type gas sensor and signal transmitter constitute a new generation of intelligent online analysis instrument.

The equipment is widely used in chemical fertilizer, chemical, metallurgy, heat treatment, the generator cooling, air separation, hydrogen production, such as on-line analysis of hydrogen concentration in the industrial production.

Features:

1. The sensor is sensitive to platinum surface with glass film, not direct contact with the gas being measured and sensor performance stability, high sensitivity, good corrosion resistance.

2. The microcomputer, big screen dot matrix LCD display

3. The man-machine dialogue, Chinese menu type choice

4. Has the function of the paperless recorder, test data, automatic storage time

5. Measurements on the lower limit alarm any Settings

6. Communication RS232 port
