`& e: F( ^' r4 c$ U2 t2 h# L! X! B8 @ 499acl-01 sensor is used for continuous detection of residual chlorine (hypochlorite and hypochlorite ion) in water solution. Its main application is to measure the residual chlorine content in drinking water, It can also be used to monitor the dechlorination process.
the sensor does not need acidification pretreatment.
it can measure residual chlorine in samples with pH as high as 9.5.
in some special cases.
it can even analyze samples with pH as high as 10.0.
but for the analysis and measurement of samples with high pH.
please consult our factory.
the linear range of residual chlorine detected by 499acl-01 sensor is 0-10p PM.
the analytical measurement above this detection range,5 V! @- z& {    r1 |; B/ X7 q: K    q% Q: m8 ?- f! } 2 }: E9 G5 `- c, _ 2 r% H" H/ U7 h8 [& H3 k    y; R499acl-01 sensor is a diaphragm covered current sensor, which is composed of (Platinum) cathode, (silver) anode and electrolyte. The cathode is covered with a porous diaphragm to allow gas penetration.
during the operation of the sensor.
residual chlorine (hypochlorite and hypochlorite ions) in the measured solution diffuses to the cathode through the diaphragm, The polarization voltage applied on the cathode reduces the residual chlorine (CL) to chloride ion (CL-1), and then generates a current that can be detected by the analyzer between the cathode and the anode. The current is proportional to the diffusion rate of residual chlorine to the cathode, that is, the current is ultimately proportional to the concentration of residual chlorine in the measured solution_( o.

because the dissociation degree of hypochlorite dissociated into free chlorine decreases with the increase of pH value.
therefore, the detection current value also decreases.
in order to maintain the measurement sensitivity of the sensor.
in order to maintain the measurement sensitivity of the sensor, the current type residual chlorine sensor only detects hypochlorite (HOCl) without sample pretreatmentCompetitors' sensors will use acidification pretreatment system, Hypochlorite is converted into hypochlorite.
the 499acl-01 sensor does not need pretreatment sample.
the residual chlorine in the sample with pH up to 9.5 can be easily detected.
to analyze the solution with pH 9.5-10.0, please consult our factory.
the residual chlorine analyzer can automatically correct the original sampling signal of the sensor.

Y" D7 f because the diffusion rate of residual chlorine through the diaphragm is related to the temperature of the solution to be measured, the response of the sensor must correct the change caused by the temperature on the permeability of the diaphragm.
PT100 RTD temperature probe is built in the residual chlorine sensor.
therefore, the sensor has a high sensitivity and high sensitivity, The analyzer can automatically correct the temperature.
(set a thermistor resistor with delta sensor for automatic temperature compensation).

the results show that the stable and low concentration of standard residual chlorine solution is difficult to be commercializedTherefore, the 499acl-01 sensor is usually calibrated according to the test results of manual sampling and laboratory analytical instruments; It can also be calibrated according to the test results of portable analytical instruments provided by other manufacturers.
