Wide Application----YINMIK YK-5 Digital pH Meter and Salt Tester

1.Nice pH Salt Tester Kit for Pool---The pH level of pool water is a measure of its acidity. The ideal pH level for pool is 7.2-7.8 , salt leverl is 2700-3400ppm. Maintaining a saltwater pool requires regular testing of pH, salinity, and total alkalinity levels, occasionally cleaning the salt cell. Ideally, you should test pH twice a week and salinity and total alkalinity at least once a month.

2. Good assistant for aquarium lovers---With YK-5 pH Meter for auqairum ,even if you are a beginner, you can easily take care of your fish. Normal pH Levels for freshwater fish is 5.5-7.5, for salt water fish is 8.0+,the salt level for saltwater fish is 26-35ppt. Detecting water parameters accurately such as nitrates and pH levels are fast and easy with this Aquarium test meter. With just a single pH Meter enables you to test your water accurately and keep your tank clean and maintain a safe environment for your dearest water pets.

3. pH Meter for Water Hydroponic---Suitable pH and EC Values for Your Hydroponic Nutrient Solution. Behind every thriving plant is a gardener who cares for her carefully. Through this 5 in 1 PH tester, you can easily grasp the environmental factors of plant growth.

4. Water Tester for Drinking Water---Testing your water using a TDS meter is the simplest way to measure for total dissolved solids. If you have a reverse osmosis system, you can use the following formula to calculate the percent rejection of TDS and to measure your RO system’s performance. TDS Calculation Formula:%Rejection=Tap TDS-RO TDS/Tap TDS*100 Example:TDS = 260 ppm RO TDS = 20 ppm Rejection = [(260 - 20) / 260] x 100 = [240/260] x 100 ˜ (.923) x 100 = 92.3. Generally, the TDS level between 50-500ppm is considered as the most suitable and acceptable. TDS levels below 50 can be considered high-quality drinking water.

Note: If the content is less than 80ppm, it is called soft water; if the content is between 80ppm-160ppm, it is called hard water; if it is above 300ppm, it is called very hard water.
