Description
Overview
GAOTek benchtop paperless temperature data logger is color TFT LCD display, completely isolated universal input such as thermocouple, thermal resistance, current and voltage, frequency input, can support multi loop flow totalizer with automatic temperature and pressure compensation function, adopts modular structure output functions such as alarm, auxiliary power supply for sensors output, retransmission, print and communication etc. Measuring data can be displayed in various types, such as graphic display as bar graph, real-time trending, history trending memory, real time circular chart, history circular chart memory and alarming state display. Also, can be printed in curve and data by mini printer through RS 232 port. At the same time, it also provides features to check the data of year, month, day, hour, minute, second directly. Recorder can be configuration with OPC server, SCADA system and other professional software with MODBUS RTU communication protocol through RS 485 port. The history data can be downloaded directly by USB flash drive, plug and play, easy and flexible. PC supported data analysis software can print the data in curve and output Excel format for further analysis.
