CI-H400L online explosive-proof hydrogen analyzer

* thermal conductivity sensor * explosive-proof

1. Introduction                                                                                                

Determining gas concentrations by measuring the thermal conductivity of the gas, CI-H400L analyzer uses advanced thermal conductivity sensor with single chip technology. It adopts platinum thread as sense organ to make up Imbalance Bridge, which output signal has a relationship with tested gas volume. And the single chip will magnify, sieve wavelength, modify linearly and criteria the signal by electric procedure. And then it will output direct ratio signal to the tested gas concentration.

2. Features                                                                                                      

* Imported corrosion-resistance sensor, intercross resistance and advanced digital processing

* Low drift electric bridge with high stability and good reliability

* Concise menu, simple operation

* Inner flow meter, flow controller, stainless steel joint and optional constant temperature control system

* Inner air pump(option)

* Setting upper and lower alarm values freely during the measure ranges

* Connected to a computer via the standard RS232 or RS485 interface.
