Pressure / Refrigeration / Air Conditioning

Testo 550 RSA Kit

Our Pressure Meters will allow you to determine differential pressure, total external static pressure (TESP), duct velocities, manifold pressures and volumetric airflow with a Pitot tube. Our digital manifolds provide fast, real-time superheat and subcooling readings! They are easy to use and provide the most accurate readings for set-up and service of all air conditioning/refrigeration systems heat pumps.  Choose from your many options below!

Whereas most analog manifold gauge sets for refrigerants have two or three refrigerant pressure readings on the gauge face, our digital Testokool manifold gauge sets have over 35 refrigerant tables in memory including three user-customizable locations as well.  Superheating and sub-cooling calculations are also included along with external, pipe wrap temperature sensors.
