Test the acidity and alkalinity of any solution with your GAOTek pH meter. A high-quality pH meter is designed to measure the electric potential of a sample. Commercial or industrial grade pH testers and meters are used every day to verify whether water and/or other liquids have not been contaminated.

 

When measuring pH in water or liquid, evidently it is accuracy which is important. You need to know you can rely on a pH meter to provide the correct reading every time. At GAOTek we have a wide range of pH meters and testers, as well as multi-function units which can also measure salinity, TDS electrical conductivity, and more. Accurate readings are one of our highest priorities when it comes to our pH meters. No matter the environment you’re in or the temperature, as long as your GAOTek pH meter has been properly calibrated, you’ll have the most accurate results.
