The outdoor transmitter with IT Instant Transmission technology represents a new generation of radio transmission. It impresses with its exceptionally fast data transmission, as the current measurement values are received almost in real-time. Depending on the settings, the transmission interval is only 4.5 or 16 seconds. At the same time, the transmission is particularly reliable and resistant to radio interference – even over a range of more than 100 meters. Another advantage is its energy efficiency: the transmitter achieves a runtime of up to 2 years with just two AAA 1.5 V batteries.
