Stationary displays for the flow, dew point, pressure sensors

D300 This is a multifunction measurement instrument for industrial applications. The basic unit consists of a LCD graphics display, 2 relay outputs, USB interface in a panel/wall mountable casing. Through various options D300 can be configured to specific customer requirements. These options include: data recording, RS-485-interface, sensor inputs for our flow and dew point sensors, sensor inputs for process signals (0-1V, 0-10V, 0-20 mA, 4-20mA) and temperature sensors (thermocouples, Pt100, Pt1000).
