The dew point thermometer for compressed air is a mobile testing device for monitoring the quality of compressed air on stationary and mobile compressed air generators. This dew point thermometer 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 dew point thermometer in the pressure lines is protected from dirt, moisture and high flow speeds. This increases the service life of the dew point thermometer's sensors.

The data memory of the dew point thermometer enables the course of the measurement parameters to be recorded in a pressure line. The data recorded by the dew point thermometer is permanently stored in the internal memory. The memory can be read out directly on the dew point thermometer. The dew point thermometer can also be connected to an operating system independent computer via the micro USB interface. This is made possible because the dew point thermometer is recognized as a mass data storage device. The data saved by the pressure dew point measuring device are saved in CSV format. The stored measurement data can thus be evaluated using any spreadsheet program.

 

- Data storage with CSV data export
- Dew point, H2O, temperature, humidity measurement
- For inline measurement of pressure pipes
- Battery operation for mobile use
- With G1 / 2" connection thread
- Sensors protected with sintered filters
