fluke multimeter with thermocouple
(OP)
I am using a fluke 189, with a type k thermocouple, made by fluke. it appears that there is a verrrrry slow response time (close to 10 minutes). does anyone have any real world experience with these?
I have several thermocouples affixed to various lines in my HVAC system, and only 1 fluke, so I must go around and plug into each sensor. Each time I plug, I am getting this huge settling time, not to mentioin wild readings. I am onsite with a big operation, and need results fast... (as usual).
Any ideas?

Could try some of these , does temp/rh

This one has two temp probes

Need some software and an optic base to go with them.
Take the "V" out of HVAC and you are left with a HAC(k) job.

Does anyone know the electronics or alogrythm that the fluke is using to replace the 0 degree refrence temperature? is this normal for a fluke? the literature specifys a 500ms response for temp readings, not 10 minutes.
I may need to purchase sensor package- I am measuring the outside of 3/8" stainless piping, which is flowing our cooling fluid, so I need a small sensor probe.
please help- i am not an hvac guy- this is a bit out of my expertise.

I also learned that a fluke has a temp accuracy of only =/- 1 C, and the probes that I had were +/- 3C. seeing as I was seeing delta T of 3 degrees, that's no good.
Bottom line- Fluke is NOT a good temperature probe!
For our system, we have gone with a system of pt100 sensors for better accuracy.

Cold ambient will slow response, that's why you have to keep the unit in an insulated case when taking LT & MT refrigerant superheats.
