Thank You,

That's exactly what I'm looking for.

My company supplied me with a UEI which I double check with my slant tube manometer.
So far it's accuracy is within 0.01" w.c.
If I were to purchase one myself it would be the Fluke.
Now I need to find surgical grade silicone tubing that won't get hard in the freezing cold.

It was 0.01" wc. Sorry for my bad typing.

I use a fluke 922, and magnahelic's 0-1.0"W.C. and 0-2.0"W.C.
Both work fine for me.

digital tpi 620 works very well confident in the results

I check my UEI with a U-tube on a reg. basis..... So far it's good.

Until I checked my Testo against the Dwyer u tube. I felt ok using the Testo 506. That was the first time I had doubts about my digital manometer. I think I will check it more often against the u-tube.

I just bought a Testo 510 about a month ago. First digital I ever bought. Checked it against my magnahelic, dead on. Last week I was a pharma lab, which has the lab pressure calibrated monthly. Pulled the hose off there magnahelic and hooked it up to my Testo, was off about 0.1". I'm happy with that.

Digital Manometer

Here is one for you. Another tech calls me at home the other night and tells me my manometer is screwed up. He was out on a call that I had done the set up on. Low fire 1.9wc high fire 3.5wc. He tells me my manometer is not working right because he hooked up his and the high fire was 2.8wc so he brought it up to 3.5wc and told the customer that everything was fine now that the gas pressure was set right.
I grab my Dwyer u tube off the truck and hook it up to my furnace and check where it is sitting. 1"3/4 down and 1"3/4 up good 3.5wc. Hook my Testo 506 up and 3.53wc. Guess who has the screwed up manometer and has to go back to the over fired furnace. He is using a UEI manometer I told him at the shop the next morning he better get a new manometer. He then tells me there must be alot of furnaces out there that he has overfired.
