Nova Analytical Systems Inc.
Nova Model 7900 series heat-treating atmosphere analyzers are designed for continuous, long-term analysis of exothermic and endothermic gas in any combination of CO, CO2, H2, CH4, O2 or dew point. Carbon potential also is available for endothermic atmospheres. Built-in sampling pumps continuously draw in a sample of the gas, which is filtered and sent to various gas detectors. Low-flow arms also are provided. All read-outs are large, easy-to-read LED meters, and either 4 to 20 mA, voltage or RS485 outputs for recording or control are provided.
