Fieldpiece SPK3 Probe & IR Temperature Pocket Tool

The Fieldpiece SPK3 is a compact dual-mode thermometer that fits in your shirt pocket and handles both in-duct probe measurements and non-contact IR surface readings in one tool. The folding ROD probe has a sharp, narrow tip for easy insertion into ductwork, and the hanging hooks let you take hands-free measurements while you work. The bright backlit display flips between IR and ROD readings, and the SPK3 quickly calculates T1–T2 across both modes — or a combination of the two.

A practical grab-and-go tool for HVAC technicians who need quick system assessments without carrying multiple thermometers. Browse the full Fieldpiece tool range or see all HVAC thermometers at HVAC Shop AU.
