Category: Dew point meters

With the DP 500 CS Instruments has combined next generation measurement technology with state-of the art user interface design. The experienced user knows that dew point measurement also requires the measurement of line pressure, since dew point is pressure dependent. With the DP 500 the line pressure is measured in combination with the dew point, so the user can be confident that the calculation is accurate and free from human error.

Unique features of the DP 500 / DP 520 Pro:
1. Similar to modern smart phones, state of the art graphical user interface with touch screen functions for ease of operation.
2. The option to use the DP 520 as a portable data collector. The data logger can record as many as 100 million values which are stored on a SD flash card. The
    card can be removed for fast transfer of the recorded information to your PC, or alternatively the information can be transferred or read via USB or Bluetooth®.
3. For DP 520 Pro: Using the portable printer MP 500 on-site print outs can be created showing the measured values, location and date/time. Of course these
    values can be stored as well for report generation in your office.
4. DP 500 and DP 520 comes in a robust transport casing including measuring chamber, battery charger, USB cable and a Teflon hose allowing for quick
    connection to the compressed air system and immediate measurements.
