For continuous analysis of up to 100% hydrogen (H2) in process gas streams. Also recommended for other applications such as H2 cooled generators, electrolysis units, refinery gas, heat treating atmospheres, blast furnace gas, and many more.
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 H2detected. 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.
