1. Environmental Monitoring Equipment
Fridge Sense

Our smart cellular GPRS Modem continuously interrogates the temperature or humidity sensors and then relays data via GPRS to our dedicated server at 5 minute intervals.

All data is available 24 hours on the internet and viewed on any web enabled computer or mobile device.

Features include Graphs, Analysis, Reports, Geographic mapping and email and SMS alerts.

FridgeSense has settable alerts for temperatures that exceed set ranges which makes it a perfect solution for monitoring fridges, freezers and server rooms etc. This includes power failure alerts.

The online control panel allows SMS and email alerts to be sent out to up to three recipients.

The standard Master unit comes with 3 temperature probes but more probes can be added by adding additional networked units via a 1 four core wire. Each additional unit allows up to 3 temperature probes each.

Due to the live wireless technology there is no required collection of data monthly or annually from each site which is an unnecessary expense in terms of time and resources.

What makes this product unique is the network topology that strings all the monitored devices together on a single four core wire making installations easier and robust. FridgeSense is able to monitor up to a maximum of 12 temperature probes by using 4 monitoring points that allow 3 temperature probes each.

All data is fed into a single location allowing multiple sites to be monitored on a single webpage making for easier national and international management.

These features should go a long way in enhancing safety, preventing produce damage and the ability to make informed go-no go decisions.

1. Weather Proof Enclosure.
