Small Dimensions, Big Performance
The affordable testo mini thermometer with alarm function is small and handy, but its performance is big. The penetration probe comes with an 80 cm cable and is permanently fixed to the thermometer base unit. When not in use, the probe and cable can be stored easily and compactly on the temperature measuring instrument itself.
This mini alarm thermometer is highly versatile, making it suitable for temperature measurement in the air, in soft powdery substances, and in liquids. Using the supplied clips, the unit can be propped up on a desk, permanently mounted on a wall, or attached to your gear for practical transportation.
Tradie Pro Tip: Stop babysitting your readings! Use the 80 cm cable to drop the probe into a cooling vat, fridge, or HVAC duct while mounting the display unit safely outside. The instant acoustic alarm means you can walk away and work on other tasks, knowing it will alert you exactly when the target temp is hit.
