need a gauge

I have a plug on the elbow of my return manifold that is crying for a nice, accurate temp and pressure gauge. Lollipop style.

Brand/model suggestions?

Thanks.

gauge

I hear the Chinese versions are to be avoided.

Temperature & pressure gauge

I suggest separate devices. I've yet to see a good combo gauge. Most of the OEM stuff is an estimate at best.

Thermometer

I found a nice one in my R E Michels catalog. They list the manufacturer as Neiss. It is a model DVU35 & uses well #E35-75BS.

Weiss

No wonder I couldn't find it elsewhere on the web. Name wrong in the stinking catalog & dummy didn't even think of Weiss.

The CTP40L looks like just the thing.

Tri-indicator

If all you want is a run of the mill gauge, that should fill the bill. I thought you were looking for accuracy.

I believe Grady is referring to the Weiss. Upon further reading, at +/- 3% over the 60-260F range, it's only accurate to +/- 6F. I already know my other sensors are within 2F, so looks like I need a better gauge as much of what I want to measure is <8F. Will keep searching. I'd like to do pressure, too.

Temp & pressure

I believe the original Weiss I suggested was +/- 1%. Pressure could be done by using a tee or drilling & tapping the pipe.
