This is our most popular and versatile logger kit.
It has a built-in temperature sensor that measures from -20°C to 60°C with an accuracy of half a degree.
It has a replaceable battery that will last 12-18 months.
It is ideal for where you are monitoring just a single item (e.g. a single vaccine fridge in a GP clinic, or the room temperature in a single room).
Add as many loggers to this kit as you need, providing they are with radio range of the Gateway.
