{pH and TDS meter for water} pH and TDS are two important parameters that determine the suitability of drinking water. The YINMIK pH TDS meter is an excellent meter for drinking water testing. It determines the ppm value of drinking water, monitors the operability of the reverse osmosis/deionisation system and indicates whether the filter element needs to be replaced. Check the pH of the alkaline water from your machine.
{pH and EC meter for hydroponics} Most nutrient solutions for hydroponics have EC values between 500 and 2400 µS/cm, the ideal pH is between 5.5 and 6.8; the temperature of the root solution should be between 18 and 26 °C. The YINMIK pH/EC meter delivers consistent and accurate nutrient measurements in your hydroponic gardening system to keep your plants balanced and healthy.
{Wide Applications}: Ideal for pH measurement of hydroponic nutrient solutions, drinking water, swimming pool/hot tub, and aquarium water. Monitoring pH in the production of wine, beer and juice, aeroponics, reverse osmosis systems and aquacultures. Any liquid whose pH value, EC or TDS needs to be measured can be used.
