Your cart is empty.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.

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.

Pros: - Fast accurate readings of two probes - Solid construction - Good battery lifeCons: - 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

I really like this Fieldpiece dual thermometer. Build is very sturdy. Accurate out of the box. Large LCD screen so I can see clearly in lighted conditions but the only downfall of the ST-4 in my opinion is that the screen is not backlit and for the price should be a feature built in.

Appears to be very accurate. Simple to use. Quality looks great. Calibrated out of box. Looks like a tool that will last quite awhile.

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.
Excelente herramienta, calidad fieldpiece.

One sensor doesn’t work, the customer service very poor, they asked me to ship back to Las Vegas, and I have to pay postage first, and they will refund $17 when the item Is received. It may cost over $40, and couple weeks. I’m really disappointed with Amazon service. No more purchase.
