(1) Adopting an integrated chip design scheme, it has self recovery and self correction functions, high accuracy, and good consistency.
(2) Automatic address allocation function. Using RJ45 interface connection, automatic address allocation can be achieved on the RS485 bus.
(3) Easy to install. There are two installation methods: magnet installation and wall mounted installation.
(4) Equipped with temperature and humidity error correction settings, convenient for regular calibration.
(5) The power input has anti reverse function, and the positive and negative connections of the power input will not damage the equipment.
(6) Equipped with RS485 interface and adopting standard MODBUS protocol, it facilitates remote monitoring system integration.
(7) It has temperature unit selection: Celsius (℃) and Fahrenheit (℉) can be set, and can be used globally.
(8) The external port has an anti electromagnetic interference design and high reliability.
(9) Modular structure, easy to install and maintain.
