The entire measurement system mainly consists of two parts: the instrument and the sensor. The instrument displays the total chlorine value (main measured value), the pH value of the aqueous solution (a pH electrode needs to be selected optionally), and the working status. It outputs signals such as analog quantity, digital quantity, and switch quantity. The sensor is of the original imported RG brand from Germany and works on the principle of the film-covered three (dual) - electrode constant current method, with the characteristics of anti - interference and anti - pollution. The sensor is not restricted by water quality conditions and can be applied in various industries.
Application Fields
Tap water: 0 - 2mg/L
Swimming pool water: 0 - 5mg/L for the measurement of cyanuric acid
Medical water: 0 - 0.5mg/L; conductivity as low as 10μS/cm
Sewage treatment: 0 - 20mg/L
Seawater: conductivity up to 50mS/cm
High - salt seawater: brine or seawater with a concentration greater than 3.5% (>50mS), and the salt content can be up to approximately 26%
Dual-channel access for configuration according to requirements.
Enables plug - and - play of sensors, making electrode installation and replacement quick and convenient.
