Alat Laboratorium Umum
The hygrometer is a mobile testing device for monitoring the quality of compressed air on stationary and mobile compressed air generators. This hygrometer measures the temperature, the relative humidity, H2O and calculates the current dew point up to an ambient pressure of 20 bar. Thanks to the sintered cap, the hygrometer in the pressure lines is protected from dirt, moisture and high flow speeds. This increases the service life of the hygrometer'ssensors.
