MEASUREMANFully Stainless Steel Bimetal Dial Thermometer, 3" Dial, 2-1/2" Stem, 50-550 deg F/10-260 deg C, -1% Accuracy, Adjustable, 1/2" NPT Back Mount

Great quality put into these meters. I bought 2 and they arived in great shape. Both reading the same temp. Definitely worth buying

The gauge looks well built and works great. The only issue I have is the listing should be more clear as to what size the stem is and what size fitting it screws into. I was replacing one with 1/4 inch and this one was 1/2 inch. Just had to remove the 1/2 to 1/4 reducer but this meant draining the tank down. Not a big deal but would have been nice to know in advance.

Seems pretty accurate. It read 73 while my thermostat said 72. It’s perfect size too, the other 2 inch gauges always seemed too small. Five stars

Pay attention installing them, the brass threads are cut deep so a little bit trickier to get a good seal.

Muy producto, excelente

In response to the reviewer who wrote, "The threads are not 1/2" but 3/4". " They simply don't understand with what they are working. These thermometers are listed as having a 1/2" NPT (National Pipe Thread) fitting. A 1/2" pipe is 1/2" on the _inside_. Pipes have a wall thickness (otherwise they wouldn't be a pipe). Therefore, the size of a 1/2" NPT fitting is quite a bit larger than a 1/2" SAE (Society of Automotive Engineers) bolt. These thermometers are exactly as described, not cheesy, work well, and will gladly buy these exact ones again if the situation ever arises.

I tested this thermometer against a laboratory-grade thermometer and found it to be quite accurate. It's well made and a good value.

I ordered them. They came exactly on time.
