Waterproof Thermo/Hygrometer

Caltech Engineering Services offers Waterproof Thermo/Hygrometer, PWT-411. This digital hygrometer allows determination of the relative humidity, dew point and air temperature for various applications at a time. Specifications usually detail that the relative humidity and the dew point temperature must be strictly adhered to as well as monitoring the surface temperature. The measurement is done with high-class capacity HC-1000 sensor. Large LCD makes working easier. Automatic switch off function protects the batteries against discharging. The instrument works on a 9 V battery (optional power adapter); and is recommended for humidity/dew point/temperature measurements in automobile, power, textile, refinery, and air-conditioning, civil, paint/coating applications. Alternative equipment for determining the relative humidity and dew point are the whirling hygrometer and dew point calculator.
