  • What is an IP Rating?

    An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress. Click for a table of IP Rating values.

    IP65 - No ingress of dust (6); Protection from water ingress: Low pressure jets of water (5).

    Auto-Off Feature

    The RT615 includes a light sensor that powers the unit off when deprived of light. When used with refrigerators that power internal lights off when the door closes, the RT615 will turn off to save battery power. When the door opens and light is available to the unit, the RT615 will power on automatically displaying the current temperature.

Simple but effective
After losing two refrigerators to compressor and evaporator failures in about as many years, I'm paranoid about monitoring the temps in my fridge and freezer. I keep one of these babies in the fridge compartment and another in the freezer. The display turns on when light strikes it, turns off in the dark -- a very nice battery-saving feature. I also like that there are no wires to deal with. The display is large and easy to read. My only suggestion for improvement is to add a more secure way to fasten the case. The included stand/hook works okay if you can hang or stand the monitor where you won't bump it, but I inevitably do. I want to add a dot of Velcro or a magnet to the back of the monitor so I can put it in a more out-of-the-way yet visible place.

Thermo Works is the best
I have the RT615 in all of my coolers and I can not say enough good thing about this product except if you are not using one of these in your cooler you need to be. Thank you!!!

Good Product
The RT615 is a good accurate product. I have purchased several in the past can't remember the exact year probably 5 years.Batteries last for years. Last purchases were gifts for my family.

Does the job
I've used it to dial in both of the ref/freezer I have. I like the fact it turns off when the door/light closes. (saves the battery) So far so good.
