商品説明

The HHF-309 is ideal for measuring all parameters needed to install, test and fine-tune the performance of an HVAC/R system. This economical meter measures temperature, humidity and air speed and can readout units HVAC technicians require such as enthalpy, wind chill and dew point/wet bulb temperatures.
