Rated 5 out of 5 by from Just what I wantedBought two of these and mounted them in a box that was attached to a wall. Also purchased the 12v 500ma AC adapter to power them, and ran one of the temperature probes to outside my house. Now I have a continuous, lighted (great at night with the auto dimming) temperature display of both inside and outside, at a glance from a distance, at any time! Running for a few weeks now with no problems.

How many probes can this unit monitor?  I see 1 2-pin, and 2 3-pin ports on the rear view.  I am looking for something to monitor 3 temperatures for my boat; inside, outside, and engine room.

Asked by: Popeye IV
Two probes can be used (internal and external). Display will show the temperature of the different probes via the DIP switch settings.

how do I power this for in a car? Please be specific......I want to make sure I purchase everything I need at the same time.

Asked by: metoo01
This is designed to run on 8.5 to 26 VDC which means it can be wired directly to a 12V source in the car. This includes a wire harness for power, so it will have everything you need to get it powered up.

Will this work in a car? And how do you power it if it will?

Asked by: metoo01
Yes this will work in a car. Since it will run on 12VDC you can power it from any power source in the vehicle.
