Fieldpiece Instruments Dual In-Duct Digital PsychrometerThe SDP2 standalone dual in-duct digital psychrometer measures both supply and return air conditions at the same time dynamically. All readings adjust automatically based on changing conditions. Because the SPD2 takes return and supply measurements at the same time, the calculations are more accurate and techs can perform needed tasks more quickly and accurately. Data can also be sent wirelessly to the HG3 or the SMAN4 for live target superheat, or full system analysis.
