The Nova 430 Series Process Hydrogen analyzer utilizes a temperature-controlled TC 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 an output recorder. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement.
