Fieldpiece ST4 Dual-Channel Type K Temperature Meter

ST4 — 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.
