Extech Outdoor Thermometers Editorial Review

The Extech TM20 Waterproof Temperature Indicator is an accurate, easy-to-use thermometer that provides fast response. Its compact size makes it easy to carry and handle, and it is perfect for HVAC use. It shows ambient temperature at startup and takes readings at the indentation short way up the tip. However, it cannot be used for setting an alarm for boiler temperature of specific values but otherwise gives accurate readings and is a handy tool for all temperature reading applications.
