Warranty14-day returnsST4 — dual-channel temperature meter for use with Type K thermocouples in HVAC/R service. Applications simultaneous T1 and T2 measurement during HVAC/R service and commissioning quick delta-T checks at supply and return, heat exchangers, coils, and ductwork temperature differential across refrigerant lines, filter driers, and accessories use with any Type K thermocouple, including optional wet-bulb probe and pipe clamps Key Features Two Type K inputs — measure two temperatures simultaneously with one handheld meter. T1, T2, and T1–T2 readout — instant comparison of both channels and the temperature differential. 0.1° resolution — precise diagnostics during commissioning and service. MIN/MAX and HOLD functions — capture or freeze unstable readings in the field. Field calibration — separate calibration trims for each channel to match the thermocouple in use. Any Type K thermocouple — works with included probes and optional accessories.
