ST4 – Dual Temperature Meter

Twice as nice.

Where to Buy

  • Great for Delta T calculations
  • Two Type-K thermocouples included
  • Accepts any Type-K thermocouple
  • Resolution of 0.1-degree F
  • Max/Min/Hold
  • Easy field calibration

Works where you need it to.

Checking temperatures in ideal conditions is easy. Checking them in the field is entirely different. We designed and built the ST4 to offer superior temperature compensation in rapidly changing situations – just like you’d face in the real-world. The ST4 stabilizes rapidly so it can quickly move from the rooftop to the walk-in and still get accurate readings faster. 

Two temps. One Tool.

The ST4 Dual-Temperature Meter measures two temperatures simultaneously using the includedType-K, wrap-tab beaded thermocouples. It finds Delta T and displays it in big, clear numbers on the LCD screen. Two calibration ports on the front are easy to use, and the magnetic hanger helps make it work anywhere you need it to. The optional ATWB1 wet bulb thermocouple will help you find target superheat or use our Type-K pipe clamps to check for blocked dryer filters.

ST4 features:

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

What’s Included:

  • (1) ST4 Dual-Temperature Meter 
  • (2) ATB1 Type-K Wrap Tab Bead Thermocouples 
  • (2) Velcro Tie-wraps
  • (1) ANC6 Clear Front Nylon Bag with Magnetic Hanger 
  • (1) 9-Volt Battery (installed)
