Soil nutrient tester, 7 In 1 Swimming Pool Chlorine PH Meter Professional SALT/ORP/TDS/EC/FAC Tester Spa Hot Spring CL Water Quality Analyzer

Details: Chlorine Meter Functions We innovate according to the water quality pens on the market, unlike the neral 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 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 /L (milligrams per litre): /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, /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 /l applies to higher concentrations. 7 In 1 Multi-functional Chlorine PH Meter Specifications : FAC : 0.1-4.0 ppm PH : 0.1-14.0 H ORP : ±999 mV TEMP : 0.1-60.0°C;32.0-140°F Salinity : 0.01%-25.00% , 0-10000ppm , 10.1-200.0ppt TDS : 0-10000ppm , 10.1-200.0ppt EC : 0-10000us/cm , 10.01-19.99ms/cm , 20.1-400.0ms/cm 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 strength in water pool salt The higher the ORP value in water, the stronrthe oxidative power and ability The ORP can reflect the residua / chlorine (FAC) level 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 ran 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 : Drinking Water 50-100 : Purified Water 100-200 : Hard Water 200-300 : Marginally Acceptable 300-400 : Ordinary Tap Water 400-500 : Mineral Water 500 + : Not Recommended for Drinking Ec for Dwc, Nfthydroponic Nutrients,Adjust The Nutrient Solution for Your Plant Growth Suitable for Aeroponic , DWC Hydroponics , Indoor Plant Grow Short Press The HOLD/TEMP KeyData Hold, Screen Display H Long Press HOLD/TEMP Key Temperature Unit Conversion Wi
