How Important are Our Gages???

**amazon** · 05-04-2004, 08:13 AM

I have four sets of gauges and the way I check my gauges is I got a Trojan tee coupler that I can attach two or three set at once and if they all read the same I know the gauges are pretty accurate. If they are not then I either calibrate them or trash them but one thing I do every year is buy a new set of 72 in hoses.

This is a fascinating discussion so far.

I still have one set of gages and they are accurate enough. I been thinking about purchasing another. What about the CPS brand gage? I like it. Does anyone recommended or not recommend it?
Thanks.

I can't wait for the next reply.

I would not want to keep you waiting Dice.

Besides normal manifold sets, a market man should at least have one dual high gauge set. It sure helps when checking your defrost differential.

As Dave has already mentioned a dual low and a dual high are a good idea.

I keep a hose with a depressor on my low side only. My common and high have none.

But my high side does have a CA1 manual depressing valve. This helps on smaller systems. I just back off the depressor and pump all the liquid into the suction side.

Plus I just don't like frozen fingers.

I'm gonna spring for the digital set soon.

I'll order them thru WalMart so if I dont like em, I can take em back and get my money back.

(24 sets of gages .... sheesh!)

And I want more.

The best way to calibrate gauges is to hook to a drum of r-22 (or whatever you have handy) that has been stored in a controlled ambient temperature for several hours. then calibrate gaug to pressure -temperature chart. this will never lie as long as you use virgin refrigerant.

OH .... and I guess you got a special one just for measuring oil pressure at the pump scraeder?!?!?!

As a matter of fact, I do.
