The Fieldpiece SPK2 Pocket-Size Digital Thermometer features a folding in-duct rod probe with a sharp tip for punching through flex duct and a stainless steel construction for increased durability. This thermometer is ideal for taking quick air temperature measurements and easily fits into a pocket for fast temperature checking. The SPK2 is capable of calculating T1/T2 temperature class measurements.

The large display on the SPK2 shows MIN/MIN/HOLD and features a bright backlight for reading measurements in poorly-lit spaces. The low battery indicator lets the user know when to replace the battery. To conserve battery life, the unit includes an auto power-off mode that will shut off after a period of inactivity. The folding rod features a hanging hook for attachment onto a duct or on a grille.
