CONTINUOUS PROCESS ANALYZER FOR HYDROGEN AND DEW POINT, Model : MODEL 430DPL, Brand : Nova

The Nova 430DPL analyzer utilizes a temperature-controlled T/ C cell for the detection of H2 in process gas. This cell produces a small millivoltage output which is directly proportional to the H2 detected. This output is then amplified and displayed on a digital readout meter and is also available as a recorder output. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement. For dew point, the 430DPL has a capacitive ceramic sensor. The output of this sensor is directly proportional to the dew point of the sample gas. After the sample gas has been analyzed for H2 and dew point, both signals are amplified and displayed on digital meters and are provided as voltage or current outputs for recording.
