Product Introduction

1. Description of Chlorine Dioxide Sensors CLD502, CLD505, and CLD510

The CLD series (chlorine dioxide sensors) uses advanced amperometric measurement technology. Designed for water treatment disinfection applications, and for use with chlorine dioxide, pools, etc., these sensors are available in three ranges to detect chlorine dioxide concentration. The detection ranges of CLD502, CLD505, and CLD510 are 0-2ppm, 0-5ppm, and 0-10ppm respectively.

The chlorine dioxide sensor outputs a 4-20mA signal, adjusted according to ranges 0-2, 0-5, or 0-10ppm. The membrane cap and fill solution are easy to replace, greatly extending sensor life.

The chlorine dioxide sensor can be installed with a flow cell for new installations, or used to replace other chlorine dioxide sensors with 4-20mA output. (Please consult us for compatibility.)

A flow meter (FM001) is available to help provide consistent flow, thereby enhancing system stability.
