Product Introduction
Sulfur hexafluoride is detected using ultrasonic principles, featuring rapid and sensitive response, wide measurement range, and long lifespan.
It also has the function of monitoring oxygen, with a range of 0-30%VOL, high measurement accuracy, up to within ±3%FS, and repeatability up to within 1%.
Optional temperature and humidity, precise measurement of environmental temperature and humidity changes.
The product adopts a 485 communication interface, standard ModBus-RTU communication protocol, communication address and baud rate are configurable, with a maximum communication distance of 2000m.
10-30V DC wide voltage power supply.
Reasonable structure, avoiding long-term accumulation of SF6 inside the housing.
