New Call-to-action
The Nova 207 Series Portable Dew Point Analyzers have been designed primarily for accurate dew point measurement of exothermic and endothermic heat treating atmospheres.

The dielectric polymer sensor provides stable and accurate dew point measurements and is not affected by most gas compositions.

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 analyzer then reads the dew point continuously.

Unique Applications

N/A

    The 207 Series should not be used to measure dew points when trace amounts of sulfur trioxide (SO3), chlorine (Cl2), hydrogen chloride (HCl), or ammonia (NH3) are present. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
