iKKEGOLDual Sensor LCD Display Indoor Outdoor Digital Thermometer Hygrometer with Max Min Memory

This was a replacement for my old 40 year old indoor/outdoor thermometer. I chose this type with a wire type outdoor sensor as opposed to the wireless type. One less battery to worry about and I wasn't sure if a wireless sensor battery would still transmit at subzero temperatures. This model is rated to -58F. The min/max feature is a great feature too. I highly recommend this thermometer.

This is my second one. The first one died, But to be fair it is in the front window of my van and when it's 100 outside the screen goes black because its 150+ in the van. when sitting in the sun. The outside sensor fits in the grill and lets me know what temp outside is. When this one dies I will get another one like it.

Quickly adjusts to change in temp

replaced my old one. Works the same.

Put a battery in. Run sensor wire out of the window. Done
