Do you have a link to the one you have or the one I am describing.

Thanks!
A search of your area may turn up a business which deals in scientific instruments.
They would have something like a FLUKE brand,digital thermometer and the thermocouples which feed the 'data' to it.
These have the useful temperature range we're interested in.
Also,thermocouples can be potted into epoxy and embedded in drain plugs 'n such.
With a rotary switch to select a 'source',all feeds can go to the single digital thermometer.You can monitor virtually all aspects of your vehicle's critical temps including coolant.
Wholesale-only HVAC supply houses will also carry instruments,but they typically do not sell to the general public.A business card is helpful there.
