Overview
These Wide Range Water Quality Testers are designed to deliver accurate monitoring of various fluids including water, sewage, and seawater under diverse conditions. Built to operate reliably in extreme environments with temperatures from -30℃ to 45℃ and 100% humidity, they ensure durability with IP68 protection. The system supports multiple communication interfaces such as RS485, USART, infrared, M-BUS, and NB-IoT wireless for flexible connectivity. With ultra-low power consumption, dual-row display, and ferroelectric storage, it provides accurate real-time data and long-term records. Its rugged construction using carbon steel, stainless steel, PEEK sensors, and nylon-glass fiber ensures stability and precision over years of continuous use.
