About Thyristor pctflow DP 500 / DP 510
The mobile dew point meter can be used with an extensive range of compressed air systems including the examination of the refrigeration system, membrane or absorption dryers.

It can also be used with other gases such as nitrogen or oxygen for residual moisture measurement.
Descriptions Of pctflow DP 500 / DP 510
The 3.5” touch screen is easy to operate and can store up to 100 million measured values within the onboard data logger. Data from the sensor can be processed on the device and displayed visually via a local graph.
Screen shots can be taken on the device of logged data to see instant trends, or the data can be downloaded to the dedicated CS instruments desktop software for in depth data analysis.
Benefits & Features DP 500 / DP 510
DP 500 comes in a kit form which includes all the necessary accessories to allow for portable dew point measurement. This includes:
