I'm finally doing my Digi-cool mod.

[jpsmith1cm]

You sure that mod will hold up?
I've head rumors that the adaptation was not 100% successful.

Is the resistance vale thru the cooper sensors the same as the DC?

If not I think that would affect accuracy,,,would it not?

HMMM....BTW....aren't you GreeK?

A 10kohm sensor is a 10kohm sensor.

I've made sensors to fit my DC that aren't DC sensors and I've made side-by-side comparisons. No problems.

A 10K is not a 10K is not a 10K They do make different 10K's

The maximum difference in resistance between the stock Digi-Cool thermistor and the Cooper probe was 0.2 ohms, from -10ºF through +200ºF.

Do you have a web link to the stuff you use?

It is actually silicon for make-up effects.
Dragon Skin FX-Pro.

I like it because it will fill in tiny voids, even under capacitors and other parts on PCB boards, but is easy to peal back off without tearing parts off the PCB.
Of course the most important thing is that it doesn't off gas anything that will eat electronics while it's curing, like a lot of silicon products do.

I've had the most success with this gauge sensor combo of any I've used.
I don't think you would like it one bit

I have been tempted to mod mine in a very similar way.

I use 2 Cooper clamps most of the time and I have a Cooper strap sensor in case space is limited or the suction pipe is large.

I'm doing a tool inventory and I am pricing the modified jack at 200 bucks lol.

Would you mind taking a couple of good pictures of the actual sensor portion of the pipe clamp probe, with the jaws open, and posting them please.
I've been thinking of getting a couple of them, but would like to see the sensor arrangement first.

Except for some minor cleanup, and putting a new protective boot on it, I'm pretty much done with them.

Fixed the booboo.
JB Weld worked quite nicely for patching the "mistake hole".


Action shot.


What's 1ºF between friends?


The little UEI was my first digital thermometer, I got it in a pawn shop for $5 about 21 years ago.
I've never had a J-type thermocouple for it, but it has always been happy with K-type thermocouples.

You need more thermometers to really get better test results :beer:

What...no infrared? What type of a tool slut are you anyway

That is just the probes that are designed for securing to a pipe, and not all of them at that.
I'm feeling to lazy to dig out air, surface and immersion probes/instruments, I tested them last month.

I don't find IR thermometers particularly useful for much besides looking for hot electrical connections and breakers/fuses, so I only have a really cheap one.
The thermal imaging camera is at the shop.
My next >$500 tool purchase will be a Fluke VT02 Visual IR thermometer, sometime this spring/summer. It will be perfect for electrical and motor diagnostics, as well as some limited duct leakage/building diagnostics on service calls.
Obviously it won't come near taking the place of a thermal imaging camera for building diagnostics, but it is something I can pack in my tool bag to every service call.

My favorite probe was the red Cooper clamp for my red or blue box. The part that sucked is they would only last a year then fail so I gave up on them
