Overview
Hospitality Enviro Tech digital 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. 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.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 server, SCADA system and other professional software with MODBUS-RTU communication protocol through rs485 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.
