Water Ion Meters

GAO’s water ion meters are devices that are used to measure the concentration of ions in water. These meters are used in water treatment plants, laboratories, and in the field to ensure that water is safe for consumption and meets the required standards. Our water ion meters work by using an ion-selective electrode, which is a type of sensor that detects the concentration of a particular ion in water. The electrode is placed in the water sample and measures the voltage difference between the electrode and a reference electrode, which is used to calculate the concentration of the ion.

GAO’s water ion meters are composed of ion-selective electrode, reference electrode, meter display, calibration solutions, and temperature probe.

The alternative names of ion meters include ion-selective electrodes, ion-selective sensors, ion-selective membrane electrodes, ion concentration meters, ion-specific electrodes, ion concentration analyzers, ion probes, ion detection systems, ionic strength meters, ion-sensitive field-effect transistors (ISFET), ion activity meters, potentiometric ion sensors and pH meters.

GAO’s water ion meters have the following functions:

  • Water Quality Analysis: GAO’s water ion meters are used to determine the quality of water by measuring the concentration of various ions. They are used in laboratories and water treatment plants to monitor the quality of drinking water, wastewater, and industrial process water.
  • pH measurement: Our water ion meters measure the acidity or alkalinity of water by determining the concentration of hydrogen ions present in the water. pH levels affect the taste, odor, and quality of water, and water ion meters help to ensure that water is at an appropriate pH level.
  • Environmental Monitoring: GAO’s water ion meters can also be used to monitor the quality of water in natural environments such as lakes, rivers, and oceans. This is important for identifying pollution and ensuring the health of aquatic ecosystems.
  • Industrial Processes: GAO’s water ion meters are used in various industrial processes where water quality is important. For example, in the semiconductor industry, our water ion meters are used to monitor the purity of the water used in manufacturing processes.

GAO’s water ion meters are often rugged, versatile and precision measurement instruments. They comply with applicable industry standards such as ISO 7888:2011, ASTM, ASTM, and EPA Method 300.0.

GAO’s water ion meters have the following applications:

  • Water treatment: pH is an important parameter for water treatment, as it affects the solubility of various contaminants and the efficiency of disinfection. ORP is also used as an indicator of disinfection efficacy. GAO’s water ion meters can be used to monitor the pH and ORP levels in water treatment plants to ensure safe and clean water supply.
  • Aquaculture: Improper levels of pH and ORP can lead to fish mortality and poor growth rates. Our water ion meters can help fish farmers monitor and maintain optimal water conditions for their fish.
  • Hydroponics: pH and ORP levels also play a critical role in hydroponics, where plants are grown in a nutrient-rich water solution. GAO’s water ion meters can be used to monitor and adjust the pH and ORP levels to ensure optimal growth and nutrient uptake.
  • Swimming pools and spas: The pH and ORP levels of swimming pools and spas must be carefully monitored to ensure the safety and comfort of swimmers. Our water ion meters can be used to check the water quality and adjust the chemical balance as needed.

Our water ion meters can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
