Product Description
Introduction
This product is a new online pH water quality sensor independently developed by ERUN Group. It features high stability and precision, automatic temperature detection and compensation, and can accurately measure the pH and temperature of solutions. It is widely used for online pH monitoring in water treatment, tap water, sewage treatment, aquaculture, surface water monitoring, and environmental engineering.
Product Features
1. LED display with intelligent Chinese/English menu operation.
2. High-impedance preamplifier: High input impedance, noise immunity, and strong anti-interference capabilities.
3. Multi-parameter simultaneous display: Simultaneously displays pH, temperature, two current outputs, and relay operating status.
4. Output signal: Software selectable 0-20mA or 4-20mA output. User-defined password: Users can set or modify their own password to prevent unauthorized access and misoperation.
