Description
Overview
GAOTek Ph meter is more economical and environmentally friendly than traditional chemical method. Small, easy to install, and can be used for continuous online water quality monitoring. Automatic compensation for turbidity disturbances, with automatic cleaning device, optional titanium alloy (corrosion resistant) COD sensors are mainly used for monitoring rivers, lakes, sewage, and other types of surface water, etc., and can be easily integrated into water quality monitoring systems to meet customer needs.
Features
- Digital sensor, RS 485 output, support MODBUS
- No reagents, no pollution, more economical and environmentally friendly
- Can measure SAC, COD, TOC, and other parameters
- Automatic compensation for turbidity interference for excellent test performance
