Dual Temperature Data Logger | HOBO MX2205 | Bluetooth Data Logger

The HOBO TidbiT MX2205 External | Internal Temperature Data Logger is ideal for temperature monitoring of fridges

The HOBO MX2205 is a waterproof data logger with both an internal sensor and an external sensor that’s designed for monitoring fast-changing temperatures.

Uses the power of Bluetooth to deliver high-accuracy temperature measurements straight to your iOS/Android mobile device, or laptop as long it has Bluetooth.

The unit has a cable approximately 2 meters in length, so you can mount the logger in the fridge or even freezer the logger can be at the top and the cable going down the fridge or at the back.

This will allow 2 measurements in the fridge, thus allows better monitoring as most fridges and freezer have hot and cold spots within.
