Humidity data-logger SRD-99

flowpressurepH

The MultiLog SRD-99 is a graphic data recorder and display designed for the measurement, recording and monitoring of process variables. It displays current values and provides graphical representation of the evolution of recorded parameters.
It can be equipped with 1, 4 or 8 universal inputs, compatible with RTD temperature sensors and thermocouples, as well as analogue current and voltage signals. This allows different types of sensors to be connected to a single device.
It also features a digital input for recording control, 2 electronic relays, internal memory, RS-485 Modbus RTU communication, and USB connections for data transfer, configuration and external storage.
