Thermochrons have been a trusted temperature and humidity logging solution for more than 20 years, and while other loggers have come and gone, Thermochrons’ unrivalled durability, reliability and accuracy have kept them at the top.

Thermochrons contain an internal Lithium battery. Depending on the sample rate, these tiny batteries can last up to 10 years.
The battery is not replaceable, so when it is depleted, the Thermochron needs to be replaced.
What affects battery life?
The main factor that determines battery life is the sample rate. Thermochrons are capable of sampling temperatures every second, but this will deplete the battery within a few weeks. In typical use, however, we expect to get 5-6 years out of the battery.
Thermochrons are very tough. They’re also fairly simple – a battery, a circuit board and a sensor, all in a stainless steel case – so there’s not much to go wrong.
That said, in every manufacturing process there are occasional duds. If you get one, we’ll offer our apologies and replace it straight away.
Some things are not covered by the warranty.
