The Nova 380 Series Tri-Gas Analyzer is designed for monitoring H2 purity inside a power generator and to monitor the purging procedure during a generator shut down or start up.
The analyzer contains a temperature compensated thermal conductivity (T/C) cell, amplifier board, digital readout, range switch, pressure regulator, gas flow control valve, pump and a flow indictor. A 4-20mA recorder output follows the active reading.
The T/C cell does not burn the sample nor is it consumed in any way, so it has a life expectancy of over 10 years. Measurement results are fast and accurate. A rechargeable battery provides power for about 8 hours of operation, and the analyzer can be used while it is being recharged.
