The environment affects us in so many ways, from how we feel through to how productive we are. The things we care about are also affected by the environment, from pets through to collectables.  In the commercial world many products are legally required to have their temperature monitored and recorded even before considering the expense and loss of reputation that products spoiled by incorrect storage conditions cause.

Perfect for a range of use cases

We have designed Tempo to be the ultimate environment monitor that combines a range of powerful features with cool aesthetics that means it looks good inside as well as out - on a coffee table or in the garden - in a factory or in a vivarium. It is robust so it can be used in industrial and commercial applications. Powered by 2xAA batteries that are easily replaceable, Tempo is wireless making it easy to use and deploy. Simply turn it on, download the free app and you are done!
