1. Product Introduction

The temperature and humidity recorder is used to measure temperature and humidity, and has functions such as temperature and humidity measurement, display, recording, real-time clock, and data communication.

The temperature and humidity recorder consists of three parts: imported temperature and humidity sensors, temperature and humidity recorders, and computer temperature and humidity monitoring software. The temperature and humidity sensor adopts imported temperature and humidity sensitive components, with high accuracy and good stability. The temperature and humidity recorder collects and records temperature and humidity measurement data, using Chinese character graphic LCD high brightness digital display, easy to operate, and can also clearly observe temperature and humidity data at night. The temperature and humidity recorder also has the functions of setting parameter power failure protection and temperature and humidity historical data power failure protection. It can save the recorded temperature and humidity historical data even in the event of a power outage. The temperature and humidity recorder follows the industrial Modbus communication protocol and can be networked with other industrial control computers or instrument groups using the Modbus protocol. The networking methods include RS232/485 bus, RJ45 Ethernet, data transmission radio, and mobile GPRS communication.

The temperature and humidity recorder has the advantages of advanced technology, high measurement accuracy, large data capacity, long telemetry distance, user-friendly human-machine interface, and high reliability; Widely used in agricultural laboratories, industry, environmental protection, health and epidemic prevention, warehousing and transportation, museums, greenhouses and other fields.
