ST4 – Dual Temperature Meter Type K

Twice as nice.

Two K-type thermocouples included
Accepts any K-type thermocouple
Resolution of 0.1 degree F
Separate MIN/MAX and HOLD buttons
Easy field calibration

The Fieldpiece Dual-Temperature Meter, model ST4, measures two 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 two 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.

Designed for HVAC/R, the Dual-Temperature Meter, model ST4, measures two temperatures and calculates the difference in English or metric units. It offers technicians all the benefits of a digital thermometer in a heavy duty design.

• Read T1, T2, or T1-T2
• Rugged rubber boot
• Min/Max and Hold
• LED indicates disengaged probe
• Great temperature compensation for fast changing environments
• Select ºF or ºC
• 2 k-type thermocouples included
• Clear front case with magnetic hanger included

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.
