Electronic environment thermometer TFA-Dostmann 30.1066.01 Indoor/outdoor Black

The TFA-Dostmann 30.1066.01 is a compact electronic environment thermometer for indoor and outdoor temperature monitoring. It displays temperatures in °C and uses a wired waterproof probe to measure outdoor conditions while the main unit remains indoors. The device stores maximum and minimum values and can switch between room and outdoor readings with a button; an automatic alternating display every 5 seconds can be enabled. It runs on AAA batteries and has a slim profile that makes it easy to place on flat surfaces, attach to metal with built-in magnets, or stand using the fold-out leg.

Advantages

The thermometer offers dual measurement (indoor and outdoor) using a wired waterproof probe, memory for maximum and minimum temperatures, and a selectable alternating display mode. It is small and lightweight, features two magnets on the back for metal surfaces, and includes a fold-out stand for tabletop placement. The waterproof sensor cable extends the application to vehicles, refrigerators and aquariums.

• Monitoring room temperature in homes and offices
