The RD300 is a remote display for level, flow, pressure, weighing, and other process instrumentation. This display also acts as a multi-purpose, easy to use rate/totalizer ideal for flow rate, total, and control applications.

Data can be remotely collected, logged and presented on your local computer using the free downloadable RD Software.  The display accepts a single input of current and voltage. This makes the RD300 an ideal fit for use with most field instruments.The RD300 can be set up as a standard panel mount, or combined with optional enclosures to allow it to house up to 6 displays.
