Tridicator, 1/2" NPT Connection, 3" Dial, 40-200° F / 0-80 PSI, Check Valve, Pressure-Temperature Gauge

great part, boiler repair

very good value

I bought two one work just fine on the other one the temperature gauge did not work. They promptly replaced the defective one, but unfortunately, the replacement one had the same temperature gauge problem. When I put the probe on an ice cube it would not go below 70 degrees. On the good one, it would drop like a rock from room temperature to 60 and then slowly on down to 40. I was using these in the attic on a geothermal heat pump piping system. So, I needed more dependability then I felt this product could give me. I love the concept, but now, back to 2 individual gauges.

Feels like a toy.

Temperature gauge works well and appears to be accurate. The pressure gauge doesn’t seem to pick up for me but that may be do to my application of the gauge.

I ordered one of there last year for my water heater (120f @ 60psi) and i liked it. So several months later I ordered another one for spare/future projects. When it arrived, the temperature needle was broke and spun around freely. These things happen in shipping so I just threw it away since it was not worth the bother to return/replace. Sadly, the first one has now broke in the same way, even though the water heater has not shock/vibration. Obviously something seriously wrong with the design since two broke the same way. P.S. I ended up ordoring a different kind. will see how this one works out.
