Fieldpiece ST4 Dual Temperature Meter (Type K)
by Fieldpiece
$209.00
The Fieldpiece ST4 is a rugged, dual-input digital thermometer built for HVAC/R service work. It reads two Type K thermocouples simultaneously (T1 and T2) and calculates the differential (T1-T2) instantly — ideal for superheat/subcooling checks, delta-T airflow tests, and coil-to-line comparisons.
Key Features
- Simultaneous T1, T2 and T1-T2 differential display
- Accepts any Type K thermocouple probe
- Two front-face calibration pots for field adjustment
- Separate MIN/MAX and HOLD buttons
- Superior temperature compensation in rapidly changing environments
- Durable rubber boot with clear front carrying case and magnetic hanger
