- The Nova 335 Portable Analyzer has been designed for the detection of hydrogen (H2) in a binary (two gas) mixture such as H2in N2. However, it can be used in some other applications with several background gases present. Consult Nova on these applications.
- The thermal conductivity (T/C) cell provides a fast and accurate measurement of H2. It has an expected life of over 10 years unless contaminated.
- In operation, a built in sample pump draws in the gas sample through the sample tube, filter and flow meter and then on to the T/C cell. The detected H2 is displayed on an LCD digital meter which has a switchable back light for use in dark areas.
- A rechargeable 'gel cell' battery provides enough power for approximately 8 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.
- Rugged design that is easy to operate
