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.

    • 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.

    • Good thermometer
Fieldpiece usually makes very good instruments. This one seems to be well built as well. The only thing I don’t like is that the k type thermocouple wires are very stiff and not very nimble. There are better k type thermocouples on the market that are more flexible.

    • 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

    • Accurate Readings
Used it the first time this weekend to check the temperature on my hvac while adding additional Freon. Worked great and I calibrated it beforehand. Temperature was very accurate. I would highly recommend. There are attachments that can be purchased. I bought the hose clamp attachment.

    • Easy to use and accurate
worked well and did the job- one thing to note , after setting the units of measurement turn the device off as will not go directly into reading microns but stays in the setting mode. After turning back on you can take readings in the units previously set. This is not explained in the manual and I sent my unit to Fiedpiece. They said it worked fine and sent it back still not making me aware of the fact that you needed to go from the setting mode to the reading mode. This could have been explained in the manual. ... show more

    • Works well and controls are well thought out.
Using a calibrated mercury lab thermometer for reference, both thermocouples were within 1 degree or less at various temperatures in liquids. Both thermocouples matched each other usually exactly and never more than a couple tenths of a degree off. This is a great tool for HVAC work. And you'll find plenty of other uses for it. I didn't calibrate mine as it wasn't needed out of the box, but you have that option too. The plastic case feels like cheap overly hard plastic. But the soft armored cover is good and makes the plastic of no concern. So I think it a pretty high value instrument vs others costing much more for the same purpose. ... show more
