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 help our customers to comply with relevant U.S. government regulations such as:

• Clean Water Act (CWA)
• Safe Drinking Water Act (SDWA)
• Good Laboratory Practice (GLP)
• National Primary Drinking Water Regulations (NPDWR)
• Occupational Safety and Health Administration (OSHA)

Our structural water ion meters help our clients in complying with relevant Canadian government regulations such as:

• Canadian General Standards Board (CGSB)
• Canadian Drinking Water Quality Guidelines (CDWQG)
• Safe Drinking Water for First Nations Act (SDWFNA)
• Canadian Environmental Protection Act (CEPA)
• Measurement Canada

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.
