Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
1) Product overview
Product Features
- The YLG-2058-01 Fine Quality Industrial Residual Chlorine Sensor is a polarographic electrochemical sensor designed for reliable, long-life measurement of residual chlorine (HOCl/ClO-) in water. It uses an electrolyte and osmotic membrane to selectively allow hypochlorite species to reach the electrodes; the measured current under a fixed potential is converted to residual chlorine concentration. Measuring range: 0.005–20 ppm (mg/L) HOCl with a minimum detection limit of 5 ppb.
