The FieldPiece ST4 Dual-Temperature Meter. This dual-temperature meter measures two temperatures simultaneously using the included k-type, wrap tab beaded thermocouple. The technology inside the ST4 provides superior temperature compensation in rapidly changing environments commonly found while performing field service. Use the ST4 to find Delta T and just about any temperature split you want to measure. It displays T1, T2 and T1-T2 in big numbers on the LCD screen, and features two front face calibration pots. It comes in our clear front case with magnetic hanger model (ANC6). Use with our optional ATWB1 wet bulb thermocouple to help you find target superheat or with our pipe clamp T/Cs to check for blocked dryer filters. This package comes with the following pieces: a Dual-Temperature Meter (ST4), two K-Type Wrap Tab Bead Thermocouples (ATB1), two Velcro Tie-Wraps, a Clear-Front Nylon Bag with Magnetic Hanger (ANC6), a 9V battery, and an operator's manual.
