PCE-DPM 3 Dew Point Meter for Compressed Air Lines
A mobile testing device for monitoring the quality of compressed air from stationary and mobile compressed air generators.
This psychrometer measures temperature, relative humidity, and H₂O, and calculates the current dew point up to an ambient pressure of 20 bar. Thanks to its sealed cap, the pressure tube psychrometer is protected from dirt, moisture, and high flow rates. This extends the service life of the psychrometer’s sensors.
The psychrometer’s data memory allows measurement parameters to be stored in the pressure tubing. Data recorded by the psychrometer is permanently stored in internal memory. The memory can be read directly from the psychrometer. The psychrometer can also be connected to an operating system-independent computer via a micro-USB interface. This is possible because the psychrometer is recognized as a mass data storage device. The data recorded by the psychrometer is saved in CSV format. This means that the recorded measurement data can be analyzed using any spreadsheet program.
