Description

The M307 monitors two temperature sensors, perfect for a refrigerator/freezer combo, two door inputs.

The M307 operates on your Wifi network to communicate with our Data Capture software.

The M307 runs for up to 6 hours without power on its internal rechargeable batteries, continuously logging data in its internal memory.

 

Stores up to a 5 months worth of data in it's internal memory which is accessed via our Data Capture software.

Stores 180 days of daily Hi-Lo temperature data for each sensor.

Our free, PC based Data Capture software, simplifies your temperature logging tasks by automatically recording the temperature status of all of your M307 units across your entire network.

 

Data Capture sends out alarm emails and text messages when a sensor goes out of limits.
