MEASUREMANTridicator, Thermo-Manometer, 2-1/2", Silicone Oil Filled, 0-160psi/30-250 deg F, Stainless Steel Case, 1/4" NPT Back Mount

Great product and really enjoy the colours. I used them for a project and didn't really need the accuracy. I bought two and hooked on the same water line that runs about 60psi. They read 10psi different, but at the price these are sold, they are not calibration prices. Thank you for providing them. I love the temperature on them too. Without the long sending bulb they take about 5 seconds to read, but exceeded my expectations for the project I needed them for.

Nice gauge – very small boat high contrast/color temperature/pressure. Will use this in my shower stall so I can tell when water is up to body temperature before I dare to step under possibly cold water, Even though I could test the temperature with my hand I don’t like doing that! Will have to use a special or manufacture a “T” connection, with A 1/8 female pipe thread fitting — in line

I previously used a "dry" tridicator and it failed in a radiant water installation after a couple of years. I read that the "wet" tridicators are better for this sort of service and this one is working perfectly after a couple of months in service (since Sept, 2021). It is smooth and more responsive than the failed one. I will return with an update as warranted, otherwise it's going strong.

I would have given 2 1/2 stars, if that was possible. Why? Because one-half of it works great - and the other half does not work at all. This was delivered today and installed this evening. When I opened it, it showed a temperature of 60 degrees. Close enough for "room temperature". Of course the pressure was not registering. There are two gauges in my heating system - one on the "in" side and one on the "out" side. This replaced the one on the "out" side since it was leaking and did not work. The one on the "in" side works just fine. Now I again have two gauges - one for each side. Unfortunately, my new one does not register pressure. The temperature is slightly higher than the other one, as it should be coming out of the firebox. So . . . with only one-half of a functioning gauge . . . and the other half working just fine, it only gets two stars since there is not a half-star.

I have only installed the 2 liquid filled. I ordered the non-liquid filled by mistake. In the photo the temperatures are off a little from each other, and there is no way to calibrate. I am using on the inlet and outlet of an air dryer to verify pressure and temperature differential. Not the most accurate, but seems to work well enough for a $12 gauge.

Better than I expected. Nice oil filled gauge. I using it on a hydro siphon for my hot water loop from my coal stove to my hot water heater.

Not useful if accurate temperature is desired. Pressure reading if fine.

This is a very nice gauge. I bought two of them.

Pressure of the Gauge seems to be accurate, but the temperature is off by ~8°F when compared to two other thermometers. When the water is running it is 52°F and the gauge will not read lower than 60°F.
