Product Description
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.
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 arbitrarily during the measurement range
Connected to a computer via the standard RS232 or RS485 interface.
