HACH KWS-400 Optical Fiber Chlorophyll Sensor
Introduction
Kacise fiber optic chlorophyll sensor measures the concentration of chlorophyll A in the water by using fluorescence principle. According to spectral absorption characteristic of chlorophyll A, the water body is
illuminated by a high-energy LED light, chlorophyll A in water body is stimulated to produce fluorescence
of specific wavelength. The sensor adopts fiber optic structure, which has excellent repeatability and stability. It does not affected by ambient light. With automatic cleaning brush, it can eliminate bubbles, reduce the impact of contamination on measurement. The sensor has the longer maintenance cycle. It has excellent stability after long-term online use.
Feature
Digital sensor, RS-485 output, support MODBUS.
With automatic cleaning brush, prevent contamination, eliminate bubbles.
Direct measurement is more convenient than traditional analysis method
On-line continuous monitoring, real-time control water quality dynamics
