QwikLook™ QT2200 service valve moisture indicator continuously monitors system moisture levels. It attaches to the low-side service valve and tightens in place of the normal service cap. It can be removed for future access to the valve. The indicator works with all refrigerants and oils. Color change indicates moisture in the system. After one week of operation, it will indicate moisture levels as low as 50 ppm. It features a patent-pending throwaway design, and includes a callback tag for the equipment owner.
