WATERPROOF THERMO / HYGROMETER PWT-105
PWT-105 is used for accurate relative air humidity and temperature measurements.
Characteristic features:
- The measurement is made with a high accuracy sensor.
- The meter additionally determines the dew point.
- Minimised size, good accuracy.
- It is possible to choose head with the following humidity sensors: GH-105 with a humidity sensor, without cable, GH-105k with a humidity sensor and a cable, GH-105p with a humidity sensor and connector for a surface temperature probe added – comparing the surface temperature with the dew point enables to decide whether painting on the surface in existing conditions is advisable.
- Automatic switch off function protects the batteries against discharging.
- Waterproof housing - IP-67.
- 24 months of warranty for the meter.
- The meter is factory calibrated.
