Description
Overview
GAOTek industrial temperature data logger of TFT true colour liquid crystal display, completely isolated universal input, such as thermocouple, thermal resistance, current voltage, temperature, liquid level, pressure, voltage, current, flow, vibration frequency input, adopt modularized structure to output alarm, sensor auxiliary power supply, forwarding, printing, communication and other functions,measurement data can be displayed in a variety of types, such as bar chart graphic display, real-time trend, historical trend memory, real-time circular chart, historical circular chart memory, alarm state display, etc. Curves and data can also be printed by small printers through RS 232 port. It also provides the function of viewing data of year, month, day, hour, minute, and second and the recorder can be configured with OPC server, SCADA system and other professional software, using mod-bus-RTU communication protocol through RS 485 port.
