Introduction to the scope of use of

industrial online residual chlorine detector [Holder HD-YL660] instrument is widely used in tap water, sewage, environmental protection, petroleum, chemical industry, electric power, food, pharmaceuticals, chemical laboratories, breeding and other industries.

product features:

■ LCD Chinese interface display, Chinese menu, simpler and more convenient operation;

■ adopts higher precision ADC signal acquisition and anti-interference circuit, higher precision and more stable;

■ photoelectric isolation 4-20mA current Output (optional);

■ RS-485 communication interface (optional);

■ Dual relay upper and lower limit alarm output (optional);

■ Sensor comes with temperature compensation;

■ Supports customized special function requirements;

Instrument principle :

uses a negative pulse with a specific voltage amplitude between the polarizing electrode and the reference electrode to selectively select free chlorine to participate in the reaction, causing it to undergo an electrochemical reaction at the cathode of the electrode, thereby forming a chlorine concentration that is proportional to the free chlorine concentration. The meter calculates the concentration of free chlorine by collecting and analyzing the current signal. Therefore, the meter has the characteristics of strong selectivity, no replacement parts, low maintenance, long electrode life, and high reliability.
