Mount this tester on a wall or place it on a flat surface either indoor or outdoors to constantly monitor temperature and humidity levels complete with MAX/MIN information.

Featuring an extremely large LCD screen, the 445713 is easy to see at a distance and readings can be interpreted from far away. The screen is divided into two portions; on the right the tester displays temperature/humidity, while the left side shows MAX/MIN values for each parameter.

The Extech 445713 can test humidity levels from 10 to 99% RH and temperature measurements from 14 to 140°F or -10 to 60°C with accuracy of ±5%RH; ±1.8°F, ±1°C.

When used outdoors the 445713 relies on an outdoor sensor that is equipped to the unit by a 35" (89cm) cable.
