Product Introduction
Adopts Swiss original imported temperature measurement unit, with high measurement accuracy and strong anti-interference capability.
Adopts remote infrared remote control technology, parameters can be modified without disassembly.
485 communication interface standard ModBus-RTU communication protocol, address and baud rate configurable, maximum communication distance 2000 meters.
Optional high-quality LCD display, values can be viewed directly on site, and can be clearly displayed even at night.
On-site power supply adopts 10~30V DC wide voltage power supply, which can adapt to various DC power sources on site.
The product adopts a wall-mounted explosion-proof enclosure, easy to install, protection rating IP66 (the cable outlet end requires the customer to use a self-provided explosion-proof flexible conduit), and can be applied to harsh outdoor on-site environments.
