A723 UHF RTU
A723 UHF RTU
A723 Series 4 uses a robust aluminum case and sturdy Binder connectors, made in Germany, that have proven to work very well since their introduction in 1998. Power consumption is extremely low, and our postcard sized solar panels are sufficient to run the show.
Connect up to 6 analog sensors from our range of environmental equipment, 2 pulse counters, 2 TTL signals (in or out) and up to 40 SDI-12 sensors. A good installation can yield distances of 1000m and more (3.000ft).
A723 addIT Series 4 is fully compatible to all current Adcon long range devices, A731/A751 addRELAY, A733/A753 addWAVE, and to the A850 Telemetry Gateway and RA440 Remote Wireless Modem. It can thus easily be integrated into existing networks.

- The addITs are particularly popular in agriculture. Optimizing irrigation systems requires the installation of soil moisture sensors in large numbers within limited areas. With several soil moisture sensors attached to only one addIT vital soil data can thus inexpensively be relayed back to base through an existing network of Adcon weather stations. The internal SDI-12 Adaptor makes the A723 addIT Series 4 even more competitive. Up to 40 additional sensors can be attached, provided they either have a very low power consumption or bring their own battery pack. Imagine this to be e.g. 5 multi-level soil moisture probes, or a big multi-parameter probe for water quality monitoring, which outputs anything from temperature, level, and pH to EC, turbidity and VOC’s.
