The product
The Coolwatcher sensor
One wireless sensor with one external probe. You mount it, the probe goes into your fridge or freezer, and from that moment Coolwatcher measures and logs that single point automatically. No WiFi, no hassle.
One sensor watches one measuring point. More fridges or freezers? You simply add one sensor per point.
Why this sensor
One measuring point per sensor
One 1 meter external probe in your fridge or freezer. Clear and reliable: one sensor, one point.
Works without WiFi
NB IoT over the mobile network, with nationwide coverage. No password, no outage when the router hiccups.
Up to 5 years on battery
Three replaceable AA batteries. If the network drops for a moment, the sensor stores the readings and sends them later.
Accurate and rugged
Measures from minus 55 to plus 125 degrees, accurate to half a degree, and rated IP67 against moisture.
