    Pipe Temperatures

    This is a survey on when you take pipe temperatures.

    Do you take pipe temperatures without your gauges hooked up as a quick check?

    If you answered yes to this question, what type of instrument do you use and what is the reason for the quick check?

    Little one warm... Big one cold and sweating if I am. Fast hit and run its workin REALLY JUST KIDDIN But it works to some extent , most of my no cooling call are just office people Remember we live in 68 to 72 degrees. Some like it 68 some 72 ... Ever deal with office women ? Especially the one under the diffuser? although nothing to do with thread ( sorry venting ) . Cooper temp probe is the one I use. And gauges also unless hit and run

    You need air temps along with pipe temps.
    Russ if your looking for new product ideas I like the testo 905-T2 but some improvements would be nice,
    backlit display
    battery door with a screw
    possibility to take a measurement and hold then bump the display like a list so you can take multiple reading sorta like a old fashioned calculator.
    Since it is a hand held device you can use smaller numbers and get it closer to read.

    This is for input for product development and I'd appreciate it if you could post your opinion here to help us develop a better product. Thanks.

    This is for a much smaller product and what i really want to know if guys take quick measurements before doing any analysis to get an idea of what may be wrong. Sort of a quick check to get his plan of attack for diagnostics.

    If the SPK1 had a pipe clamp on it also, would be great for getting Approach,
    line temps and insertion temps in duct work and Petes Plug applications, etc.

    Just not the current clamp design, don't like that one..........GF..

    I use my Fluke 68is IR temp gun for very quick readings. I understand that its not exactely the same as a thermocouple that is wrapped in insulation, but its within a few degrees. This allows me to get a great feel for the system without attaching or hooking up anything.
    Extended dehydration is the key

    You can't get much smaller than the 905's Russ
    Its a pocket thermometer with three AAA so you never need to change them (another plus)

    temp clamp

    Hey Russ. I use your clamp ATC2 on my meters and SMAN2. Wish it had 1) better temp resistance than it does. I have broke the ends off many of these when checking -20 degrees, and just melted two when I was checking a discharge line temp.They melt at 250 degrees.The compresssor won't be far behind. 2)Make different sizes. I need one for 1/4" to 5/8" lines about the size of a 5/8" imp tubing cutter. Also a 3/4" to 1 1/8" about the size also of a small tubing cutter. I ran into a situation on a case that none of my clamps would fit and I couldn't get my hands in there to wrap a probe on the 7/8" line.
    Also put some aerogel mix behind the sensor plate to stop the clamp handle from messing up the reading. (Google aerogel- it's awesome). Other tan that I have few opinions.

    Interesting.... Which product and where did you get it Dex? http://www.aerogel.com/products/overview-product.html
    Will it absorb moisture if you get it wet?

    I would like to see wireless k type clamps to use with my NEW SMAN3 so I could take more accurate superheat readings from the outlet of the evaporator coil while I am at the condenser where my gauges are hooked up. Thanks for listening.

    Itsiceman, got the aerogel on ebay, but in native form is too brittle. However, you can get it mixed with fiberglass pad which is possibly stronger but not as good an insulator. Couldn't hurt to try some.
