Our low cost, full featured, easy to use and deploy NetGuards are our latest Temperature Guard offering.

Two models available to operate in either wired (M308) or wireless (M309) Ethernet networks.

 

They are designed to simply and easily monitor a refrigerator/freezer storing temperature sensitive drugs and samples at a very competitive price.

Description

The M308/M309 share identical specifications.  The only difference is which type of Ethernet network they operate on.  The M308 operates on a wired network, the M309 operates on the wireless (wifi) network.

 

The M308/M309 can monitor two temperature sensors and two door inputs, which is perfect for a fridge/freezer combo unit.

Runs for up to six hours without power on its internal rechargeable batteries, continuously logging data in its internal memory.

Stores up to five months worth of data on the M308's internal memory.

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

 

Download the temperature log file via our free Data Capture software.

 

Our free PC based Data Capture software simplifies your temperature recording tasks by automatically recording the temperature status of all of your M308/M309 units across your entire network. Data Capture also sends out alarm emails and text messages when a sensor goes out of limits.
