6721 Dew Point Switch Meters

0555 6721 Dewpoint Switch (includes 0554 0647 sintered stainless steel fileter as standard) - 30 to + 30°C temperature pressure dewpoint (tpd) by Testo

The testo 6721 is a low-budget dewpoint guard with two switch contacts for controlling and monitoring refrigeration and adsorption dryers.

The continuous monitoring and control of compressed air dryers was up to now often not economically viable. The testo 6721 closes this gap. Whether integrated as a component in the dryer or pneumatic machine, or installed by the customer: With this compact solution, you increase the efficiency of your dryer. At the same time, you avoid follow-on damage to systems and products caused by excessive humidity in the compressed air.
