Non-reagent type residual chlorine meter

Water supply, simple water supply, etc., dedicated free residual chlorine meter for purification, distribution, and supply of water.

This is a cost-effective residual chlorine hygrometer that continuously measures free residual chlorine in water supply systems. The measurement section has a simple structure without mechanical drive components like rotary or micro-vibration types, and by combining mechanical polishing cleaning with beads and electrochemical cleaning functions through external operation, it prevents chemical contamination of the electrodes, ensuring stable operation over a long period.

basic information

【Features】 ■ Adopts a three-electrode polarographic sensor, making it less susceptible to interference from substances in the water and conductivity, allowing for a wide range of water testing. ■ Unique dual electrode cleaning mechanisms prevent degradation of sensor sensitivity. Cleaning Mechanism 1: Continuous mechanical polishing and cleaning of the electrode surface using bead cleaning without mechanical drive components. Cleaning Mechanism 2: Electrochemical cleaning function that cleans the electrochemical contamination on the electrode surface. → These cleaning functions make it less likely for sensitivity to decrease, thus reducing maintenance frequency. ■ Various output signals enable concentration control and remote monitoring. Concentration transmission signal output (DC 4-20mA), control contact output, and upper/lower limit contact output allow for automatic injection control of chlorine agents and remote monitoring. Additionally, by attaching an MMC/SD memory card, it can also be used as a residual chlorine measurement logger. ■ Less affected by the pH value of the water, capable of measuring up to pH 8. ■ Simple structure, making operation and maintenance easy. ■ Easy installation according to the location, whether wall-mounted or on a stand. □ For other functions and details, please download the catalog.
