Here's a great little product

hr

will read two temperatures,has a three year battery and can be 24 V powered which will priority the battery, also. It will record and keep min or max temperatures. C or F scale.

What a perfect way to watch delta T's for a period of time! Answer those nagging questions as to what really goes on in long loops, cold vs warm rooms, etc, etc.

A recent price reduction makes this an excellent buy! I can think of dozens of applications for a gauge like this :)

I'll put this one through some testing in the next few days.

thanks, how do you find these things

if the sensor probe are compatible with tekmar controls, then there’re a cheaper way to buy them, if you want to put up series/parallel sensor arrays for temperature averaging

Ie two parallel rows of two sensors in series, give you four space sensors still at a mean 10k ohms, or three rows of three, four rows of four etc

Thanks

HR,

I had a phone conversation with them on the shipping.
It's UPS, to cross the boarder and ship to US it's $15 for one $20 for two & $22 for three.
I thought it was stiff, it's crossing the boarder that makes high.

Good find and they thank you for posting it.
