calibration

DESCRIPTION
The Nova 203 Series Portable Dew Point Analyzers have been designed primarily for accurate dew point measurement of endothermic and nitrogen/ hydrogen heat treating atmospheres, instrument air, and in many other applications. This is a Low
Range analyzer in that it is well-suited for dew point measurements that are typically below the readable range of typical dewpoint equipment, such as the Nova 202 Series. The dielectric ceramic sensor provides stable and accurate dew point measurements and is not affected by most gas compositions, oil vapors, or particulates in the sample.
A built in sample pump draws in samples that are of insufficient pressure from the process. The sample flow is shown on a small rotameter with valve. The sampling pump can be switched off when sampling gases under pressure. The analyzer then reads the dew point continuously and displays it on a bright digital display. The analyzer can also produce an optional 4-20 mA output for data recording.
