Rated 4 out of 5 by from Does the job I bought this a month or so ago and am happy I did.

Rated 5 out of 5 by from Consistent readings. Love 'em. I am using two of these to monitor the performance of a heat exchanger in my residential solar hot water system. Probes are placed beside 1/2 inch copper pipe and covered with insulation. I ordered the first one several years ago and just got the second one. For my purposes, accuracy or consistency of readings is very important, so I was glad to see that any differences in readings between the 4 sensors on the two meters appear to be no more than one or two tenths of a degree Fahrenheit.

Rated 5 out of 5 by from Better than dial thermometer I’m able to see what the temperature is anywhere in the sugarhouse. I’m able to see the sap become pure maple syrup.

Rated 2 out of 5 by from Long delivery time And usage logic is poor It is not very intuitive at all and in fact is hard to use. Who wrote the programming for this?
