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
