BGT RS485 4-20mA 0-5V 2-in-1 IoT Water Quality Monitoring Tester
High-precision dual-signal output (RS485 & 4-20mA/0-5V) for seamless IoT integration in agriculture, aquaculture, and hydroponics. Industrial-grade epoxy-coated sensor ensures long-term durability in harsh environments. IP68 waterproof design with titanium alloy electrodes for corrosion resistance, delivering stable pH and EC readings (0-14pH, 0-20,000μS/cm). Automatic temperature compensation (0-60°C) eliminates manual calibration errors. Plug-and-play setup with Modbus RTU protocol, compatible with PLCs, SCADA, and cloud platforms. Ideal for smart greenhouses, wastewater treatment, and precision irrigation systems. Low-power consumption (DC 12-24V) for 24/7 remote monitoring. Ships with calibration solutions and abrasion-proof cable. Factory-direct pricing for bulk orders.
