• The dual-temperature meter, model ST4, measures two temperatures and calculates the difference in English or metric units LED indicates disengaged probe Rugged rubber boot Minimum/maximum/hold Select deg F or deg C Separate min/max and hold buttons Easy field calibration 2-1/2 readings/sec Between the rubber boot and clear-front case there is enough protection for even the most demanding user Use the magnetic hanger attached to the back of the case to view the display at desired height

The Fieldpiece dual-temperature meter, model ST4, measures 2 temperatures simultaneously using the included k-type, wrap tab beaded thermocouples. 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. Displays T1, T2 and T1-T2 in big numbers on the LCD screen. Features 2 front face calibration pots and 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. Because of the technology employed inside the ST4, it offers superior temperature compensation in rapidly changing environments commonly found while performing field service. Meters with thermocouple adapters often take a long time to stabilize due to transfer of ambient heat. The ST4, as with all of our k-type thermometers and meters, stabilizes rapidly so you can take it from the rooftop to the walk-in and get more accurate readings faster than the competition. Plus it includes the rugged rubber boot and the hanging bag for easy, hands-free testing, while you're working on the rest of your call.
