Nova Model 430N12 process hydrogen analyzer is suitable to continuously measure hydrogen in applications such as annealing, neutral hardening, brazing, sintering and glass/metal sealing. It has a long-life temperature-controlled thermal conductivity cell for the detection of hydrogen. Special versions are available that continuously compensate for the effects of other thermally conductive background gases, such as CO2 or CH4. The analyzer has a bright LED display meter and a 4-20 mA output. Options include alarms, built-in pump, calibration valve, pressure regulator and isolated outputs.
