• Complete with 2 type K bead wire probes (-58 to 482F/ -50 to 250C) and 4 AAA batteries

This dual input hygro-thermometer psychrometer has two type K external probe inputs for superheat plus memory. This is great for collecting information and then comparing and contrasting it against the air temperature as well as collecting the dew point and wet bulb temperatures. Great for hot environments such as engines or electronics where you need an accurate surface temperature as well as other atmospheric data. Also great for determining the relative humidity all in a rugged and easy to use design.
