The robust enclosure features an external antenna and an optional display.

The EE244 wireless transmitter is powered by four alkaline AA batteries, but can also be connected to an external power supply. Depending on the number of probes, the physical quantities measured, and the sampling and transmission rate, the batteries may last up to 3 years.
