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

The data memory of the Heat Stress Meter enables the course of the measurement parameters to be recorded in a pressure line. The data recorded by the hygrometer is permanently stored in the internal memory. The memory can be read out directly on the Heat Stress Meter. The Heat Stress Meter can also be connected to an operating system independent computer via the micro USB interface. This is made possible because the Heat Stress Meter 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.
