Fieldpiece Instrument’s wireless four-port digital manifold, the SMAN4, has four ports and a built-in vacuum gauge. HVACR professionals can now evacuate a system, pull a vacuum, add refrigerant, and dial in the charge without unhooking their manifold. The wireless function allows techs to charge to real-time simultaneous superheat and subcooling. The SMAN4 can receive indoor wet bulb data wirelessly from the SPD2 dual in-duct psychrometer.
