1、 Product Usage:

The YZ-2Z multi ion water quality analyzer is suitable for detecting residual chlorine, total chlorine, compound chlorine, chlorine dioxide, and chlorite concentrations in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control the concentration of residual chlorine, total chlorine, compound chlorine, chlorine dioxide, and chlorite in water to meet the specified water quality standards.

2、 Product principle:

This instrument adopts the DPD method,This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method, eliminating human errors and greatly improving measurement resolution. When measuring, the water sample will change color when the reagent is poured into it. Then place this water sample into a photoelectric colorimetric stand, and the instrument will compare the color depth to obtain the concentration of each ion.

3、 Technical parameters:

4、 Product features:

1. Microcomputer, touch sensitive keyboard, full Chinese menu, backlit high brightness LCD display for numerical values, operation and calibration process all in Chinese prompts, easy to use.

2.Automatic zeroing and5Automatic point correction, with non-linear data processing and data smoothing functions.

3. This instrument adopts a specially designed high-intensity long-life light source, and a unique constant light source semiconductor emitter makes its light source constant and stable. The light source has a lifespan of up to 20 years and can be used directly without preheating when turned on.

4.Year Month Day Time Display, equipped with data storageThe query function can meet GLP requirements.

5. The host is equipped with a high-power battery, which can be used for both laboratory and field quantitative measurements. It can be used continuously for 4 hours and is ready to charge.

6. Adopting a rectangular optical glass colorimetric dish, the surface is smooth and polished, overcoming the measurement error caused by uneven thickness of the tube wall in the circular tube colorimetric dish, with good repeatability and more accurate measurement.

7. Advanced technology, in compliance with the national standard GB5749-2006 for drinking water hygiene.

Little knowledge | What is residual chlorine?

Residual chlorine refers to chlorine added to waterdisinfectAfterwards, in addition to consuming a portion of chlorine through interactions with bacteria, microorganisms, organic matter, inorganic matter, etc. in the water, there is still a remaining amount of chlorine, which is called residual chlorine.

There are generally three forms of residual chlorine in tap water: 1. Total residual chlorine. Contains free residual chlorine and compound residual chlorine. 2. Free residual chlorine. Contains substances such as HOCl and OCl -. 3. Chemical residual chlorine. Contains substances such as NH2Cl and NHCl2.

If the residual chlorine concentration in tap water is too high, the main hazards include strong irritation and damage to the respiratory system. Easy to react with organic matter in water, producing carcinogens such as chloroform and trichloromethane. As a raw material for production, it may have adverse effects.

At present, China's drinking water standards have clear regulations that the residual chlorine content in tap water shall not be less than 0.3 milligrams per liter.
