Dewpoint Meter. Sensor Storage - When not in use the sensor is retracted in a molecular sieve container. |
Features
|
- Sensor
Storage - When not in use the sensor is retracted in a
molecular sieve container. The sample gas pressure activates
a piston which automatically moves the sensor into the
sampling chamber.

units and mode, audio alert
- Engineering
Units - ¡ÆC, ¡ÆF, PPM, lbs. H2O/mm scf, gm. H2O/m3
- Controls
- 5 push buttons, all settings stored in EEprom. Manual
Sensor Actuator
