SH-COL200 Color digital probe
Overview
The Color online digital probe is a dual-beam, probe-type intelligent device, which effectively reduces turbidity interference through automatic compensation, and comes with a cleaning brush to avoid the influence of adherents and air bubbles on the measurement. The probe adopts RS485 interface and standard Modbus protocol to quickly react to the change of water color.
Product features
- Self-cleaning function removes light window stains and air bubbles, maintenance-free
- Dual optical path detection, automatic deduction of turbidity interference
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
