PIC Gauge B2MS-E 2” Dial Size, 0/150°F, Surface Mount, Magnetic Connection, Black Steel Case Surface Mount Thermometer

I works

Not fancy but works like it should

This gauge appears to be of high quality and the mounting magnet is strong. I placed this on the metal ductwork of the air handler, downstream of the A coil. I can now check on the performance of the AC compressor at a glance. If I see less than normal temperature reduction in the airflow, I know I have a problem with the unit.

easy to read , checked against another unit -- accurate , strong magnet ---- and back when i was working we used them in our lab so i knew the quality using on stack for wood stove

These little guys are pretty good for the price, depending on your use. We use them to monitor some of our lab ovens. They’re good for general checks but are not as accurate as some pricier models.

I was worried that my outdoor boiler temp gauge was not accurate, put this next to it and both agreed. Now i have it on my fireplace chimney pipe so i can see the temp.

This item is perfect for the job. The temperature is exact in it's reading. Credit where credit is due. A excellent product

The visual peace of mind to monitor flue has exhaust temp.
