Fieldpiece SPK3 2-in-1 Pocket Thermometer

Fieldpiece SPK3 — a compact, multi-function 2-in-1 pocket thermometer designed for fast, convenient diagnostics on HVAC/R systems.

Applications

• Supply and return air temperature measurement directly inside ductwork
• Temperature differential (ΔT / T1-T2) monitoring across evaporators, condensers, and heat exchangers
• Non-contact surface temperature measurement of supply grilles, pipes/pipework, and other surfaces
• Quick verification of air heater performance and refrigeration system operation

Key features

• 94 mm needle probe (ROD) — sharp, narrow tip for easy insertion through standard test ports in ductwork.
• Non-contact IR pyrometer with 8:1 optics — instant (0.5 s) safe surface temperature readings from a distance.
• Automatic T1-T2 differential calculation — continuously displays temperature difference (e.g. IR vs. ROD, ROD vs. ROD, or IR vs. IR).
• Retractable hands-free hook — lets you hang the thermometer on a duct edge for stable, unattended duct measurements.
• Backlit rotating display — auto or manual orientation adjustment for clear readings at any angle.
• Exceptional battery life — up to 750 hours continuous use with the needle probe (ROD), up to 40 hours in IR mode.
