Item # Model 207RT, Model 207RT, Remote Dew Point Transmitter with Flow-Through Chamber


The Nova 207RT Series Portable Dew Point Transmitter have been designed primarily for accurate dew point measurement of atmosphere gas flowing from endothermic gas generators, at slightly positive pressure.

The 207RT may be mounted anywhere on the gas main between the generator and the furnace. The dielectric polymer sensor provides stable and accurate dew point measurements and is not affected by most gas compositions.  (some exceptions)

Because there is no built-in sample pump to draw in a sample, the positive pressure produced by the generator pushes the sample into the flow-through chamber. The sample flow is shown on a small rotameter with valve. The analyzer then reads the dew point continuously.

Unique Applications
The 207RT Series Dew Point Transmitter 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.
