It accomodates up to 3 sensing probes, which can be plugger directly onto the EE244 basic unit or with a connection cable up to 10m long. The robust enclosure features an external antenna and an optional display.
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.

Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
