Description

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.

    • Quality temperature meter
I love this thing. My GF thinks I'm crazy because I take reading all across my house. Ideal for measuring delta T temps from return and supply. I also use it to measure subcooling and superheat. Easy to use and calibrate using ice water.

    • Works well
Pros: - Fast accurate readings of two probes - Solid construction - Good battery life Cons: - Have to press a button to switch between the two probes, would be nice if both could be seen on screen at the same time - It's a tad bulky - The thermocouples it came with were poor quality and both broke quickly - The carrying case it came with is pretty bad and I ended up just tossing it ... show more

    • Trimpots a little dirty
This works well and seems to be accurate, but the two trim pot contacts seem to be a bit dirty out of the box. The readings were jumping around until I pressed down on the trimpots with my thumb. Then the readings became stable.

    • Accurate reading
Surprisingly, we bought this for our smoker. The wireless thermometers we have bought were way off in temp. My husband, who does HVAC work, suggested we should try using this meter. I have 2 probes and that plug in to the meter and cooking has been FAR more accurate.

    • This is a great piece of equipment
This is a great piece of equipment. I needed something accurate and reliable for performing work on commercial refrigeration equipment. Having the capability to calibrate each thermocouple independently is 100% necessary, and make sure you do so upon arrival. I would also do so everytime you put a new thermocouple in. The rubber boot and case are also handy. And the Velcro straps will hold me over until I decide to dish out the money for clamp type thermocouples. I was thinking of going with a cheap knockoff but am extremely happy that I decided to spend the money and get something that will last. And look professional while doing so. ... show more

    • Very accurate
This meter is very accurate and works great. I found the included thermocouples cumbersome to work with so I went out and bought the clamp on style. I turned the included thermocouples into wet bulb thermocouples with an old hollow shoe string and alligator clips.
