Nova Analytical Systems Inc. Continuous Low Range Dew Point Analyzer Model 253PM

The Nova 253 Series Continuous Analyzers for Low Range Dew Point have been designed primarily for accurate dew point analysis of heat treating atmospheres, instrument air, or other applications which may have typical dew points that are lower than what can be read by standard dew point analyzers, such as the Nova 252 Series. The dielectric ceramic sensor provides stable and accurate measurements and is not affected by most gas compositions, oil vapors, or particulates in the sample. A special built-in absorption filter removes oily vapors when sampling furnace gases.A built in sample pump draws in samples that are of insufficient pressure from the process. Alternatively, a regulator can be supplied where the sample gas is under pressure. The sample flow is shown on a small rotameter with valve. The analyzer then reads the dew point continuously and displays it on a bright digital display.
