The easy to use DewTech 390 Precision Hygrometer offers low dew/frost point or trace moisture measurements at a very attractive price.

The DewTech 390 is easy to install into standard cabinets or 19 inch rack systems. Connections to the DewTech 390 are simplified. You need only to install power, user interface to outputs, and sample gas input/output connections. That's it. Turn the unit on and the DewTech 390 automatically goes through start-up and self-check procedures.

At the core of the DewTech 390 is three stage, Peltier cooled primary method chilled mirror sensor. For peak efficiency, the performance of the Peltier is maximized through an integral cryo-cooling refrigeration system.

Ideal for metrology labs, scientific research and process measurements, standard configurations include benchtop or 19 inch rack mount.

IMPROVE reliability and precision with the Automatic Balance Control, self-diagnostics, and extreme accuracy of the DewTech 390.

REDUCE the drain on your budget! The DewTech 390 offers precision and reliability at an attractive price.

ELIMINATE faulty readings and wait-time for replacements because of drift or the typical short life of other hygrometer sensors.
