Nova Analytical Systems Inc. Heat Treating & H2 Processes Analyzer Model 7900P-4A

The Nova Model 7900P Series Heat Treat analyzers utilize a three channel high stability infrared detector for the simultaneous measurement of CO, CO2, and CH4 in exothermic or endothermic gas mixtures. In addition, the analyzer can be supplied with a fully compensated thermal conductivity cell for H2. A separate O2 detector can also be supplied for measuring low (PPM) or percent levels of oxygen in the atmosphere gas stream. Dew point is detected by a dielectric ceramic sensor and is available in standard and low ranges. All detected gases have a separate LCD digital readout and a linear recorder output. The customer may choose any combination of gases to be measured.The 7900P series analyzers are complete with integral sampling pump, rechargeable battery, filters, flow meter, and sampling hose. Solenoid valves are used to isolate low range dew point and O2 sensors during purges and when analyzer is not in use to prevent ambient air contamination of the sensors and greatly reduce purge time during start-up.
