What are addIT devices?

Adcon’s addIT devices (A720, A723 and A720B) are uniquely suited to your remote measuring needs. The A720 and A723 devices are remote telemetry units (RTU) that can be used with Adcon and other compatible sensors to track those parameters important to you. And the A720B device, in conjunction with your computer, is a base station that offers many ways for you to view and manipulate the data received from the RTUs.
