METER PWT-8A
PWT-8A is a stationary device measuring relative air humidity and temperature.
The currently produced version of the instrument is equipped with two LCDs (one for temperature and one for humidity). There are two models available:
- PWT-8A1 which measures only air humidity and temperature,
- PWT-8A2 which measures air humidity and temperature and also contains temperature and humidity relays. The air humidity and temperature thresholds can be set using the knobs on the side of the device.
To calibrate and test the PWT-8A the manufacturer uses a high quality humidity generator DGW-2 which was certified by the National Institute of Weights and Measures in Warsaw.
