【Unique Chlorine Meter Functions 】We innovate according to the water quality pens on the market, unlike the general multi-function water quality pen, our YY-1070 7 In 1 water quality test pen, in addition to measuring PH, SALT, ORP, TDS, EC, TEMP, can also measure FAC = Chlorine (CL). Chlorine (CL).
CL Usually Refers to Chlorine. FAC is Free Available Chlorine.
The difference in units between FAC (Free Available Chlorine) and CL (Chlorine) reflects the different nature of their measurement and representation. Although they both relate to chloride concentrations, they are expressed in different units because of their different uses and environments.
The unit for FAC (Free Active Chlorine) is PPM (Parts Per Million): PPM is a unit of concentration that expresses the amount of a particular substance contained per million units of mass. In water quality testing, the concentration of free active chlorine is usually expressed in PPM, which means how many molecules of free active chlorine are present in one million molecules of water. This expression is suitable for describing relatively low concentrations, such as the concentration of chlorine added during disinfection, which is usually at a low level.
CL (chlorine) is expressed in mg/L (milligrams per litre): mg/L is a unit of mass concentration that expresses the mass of a particular substance contained in each litre of solution. In water quality analysis and water treatment, mg/L is commonly used to express the concentration of chlorine. This expression is suitable for describing higher concentrations, such as the concentration of chlorine already present in a body of water.
PPM applies to relatively low concentrations, while mg/l applies to higher concentrations.

Accurately Measures Residual Chlorine Levels To Keep Pool or Spa Chlorine Levels Within Safe Limits ：Suitable for Swimming Pools ，Hot spring，Spa
ORP Meter：The ORP value is a measure of the oxidative poweror sterilization strength in water pool salt The higher the ORP value in water, the strongerthe oxidative power and sterilization ability The ORP can reflect the residua / chlorine (FAC) levelsn the Saltwater pooL.
Remarks : Pool pH should be between 6.5-8, ORP should be between 487-840, FAC value will be displayed normally. Any of these two values out of range will not display properly.
Salinity Can Be Displayed As PPm - PPt-%（1000ppm = 1ppt）：Suitable for Aquaculture , Aquarium , Family kitchen , Food Processing
The Lower The Tds Value The Purer The Water Quality ：Suitable for Tap-Water , Bottled Water , Mountain Spring Water
0-50 : Ideal Drinking Water
50-100 : Purified Water
100-200 : Hard Water
200-300 : Marginally Acceptable
300-400 : Ordinary Tap Water
