Warranty14-day returnsFieldpiece SPK2 — a folding, ultra-compact pocket duct thermometer built for fast air temperature diagnostics in ventilation, air conditioning, and heating systems (HVAC/R). Applications Supply and return air temperature measurement directly inside ductwork Quick temperature differential (ΔT / T1–T2) determination across evaporators and condensers Monitoring air heater and refrigeration equipment performance Air temperature measurements at supply grilles and diffusers Key features Folding probe with hook — the long metal probe slides easily into ducts, and the built-in hook lets you hang the thermometer hands-free for stable duct readings. Quick T1–T2 differential calculation — stores the first reading and compares it to the next, giving an instant ΔT readout. Practical measurement functions — Min/Max memory and Hold to lock the current reading on screen. Exceptional energy efficiency — up to 8,000 hours of operation from a single AA battery, virtually eliminating battery changes. Auto power off — shuts off after 15 minutes of inactivity to protect the battery. Rugged design — fold-away probe protects the tip against mechanical damage in a pocket or tool bag.
