18~36V Online Chlorine Meter For Industrial Disinfection Measurement

18~36V Online Chlorine Meter For Industrial Disinfection Measurement

Introduction

When chlorinating disinfection, the amount of chlorine input should generally meet the chlorine demand for killing bacteria to reach the designated disinfection index and oxidizing organic matter, and the residual chlorine required for inhibiting the re-reproduction of pathogenic bacteria remaining in the water. At the same time, if the dosage is too high, it is easy to produce carcinogens such as trichloromethane and tetrachloromethane. Therefore, it is very important to properly control the amount of chlorine added in the water treatment process.

Advantages Of The Online Chlorine Meter

1. Menu password can be set to facilitate hierarchical management;

2. The languages that the system can display include at least Chinese and English. The user can choose whether the displayed data is timely response or smooth response by adjusting the display rate according to observation habits.

3. The standard configuration is equipped with 2 settable 0/4~20mA active current loop outputs, and each current output allows the user to specify what measurement value it represents.

4. The standard configuration is 2 settable SPST relays. The setting objects include: alarms for the high and low values of the measurement parameters, the control of the cleaning cycle of the sensor. The warning of the working environment temperature of the instrument itself in harsh environment, as an auxiliary means of hazard protection, the maximum load of the relay is 3A/250VAC.
