Description for Fieldpiece ST4

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 a clear front case with magnetic hanger model ANC6. Use with our optional ATWB1 wet bulb thermocouple to help you find target superheat or with Fieldpiece's pipe clamp T/Cs to check for blocked dryer filters.

How Does It Work?
Plug in one or two of the supplied k-type thermocouples and find T1, T2, or T1-T2. The ST4 has been designed to be used while inside the carrying case. Use the magnet to hang it. The front is clear so you can press the buttons and read the display. The zippers allow the thermocouples to exit from the top of the case.

1. Turn on the ST4
2. Select ºC or ºF
3. Plug in one or both of the k-type thermocouples to the top of the ST4. The red LED will light up when a necessary thermocouple isn't engaged.
4. Press "T1" for the left thermocouple. Press "T2" for the right thermocouple. Press "T1-T2" to get the real-time difference between the two thermocouple readings.
5. Select temperature resolution by pressing the "1º/0.1º" button.
6. "HOLD" keeps current reading on screen until "HOLD" is pressed again.
7. Press once to record MIN and MAX. Press once to toggle between MIN and MAX. Hold down for 1 second to exit the MIN/MAX function.
8. Operate the ST4 in its case to take advantage of the hanger. You can operate the ST4 while still in the carrying case because of the clear front window.

Features and Benefits

  • 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

Competitive Advantages
There are other digital thermometers and dual temperature meters out there. This one is unique. Because of the technology, the ST4 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 to the adapter while in a pocket, in the back of your truck, even the heat generated while in your hand. 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.
