Water pH Meters

GAO’s water pH meters are devices that measure the acidity or basicity of water. pH is a measure of the concentration of hydrogen ions in a solution and ranges from 0 (most acidic) to 14 (most basic). A pH meter consists of a probe that is inserted into the water sample, and a meter that displays the pH reading. The probe of a pH meter contains a glass electrode that is sensitive to the concentration of hydrogen ions in the water. The electrode generates a voltage that is proportional to the pH of the water, which is then read by the meter and displayed as a numerical value.

 

GAO’s water pH meters are composed of probe, reference electrode, pH meter display, calibration solution, temperature sensor, and battery.

GAO Tek’s water pH meters have the following functions:

  • Measure pH: The primary function of GAO water pH meters is to measure the pH of water. pH is a measure of the concentration of hydrogen ions in water, which determines whether the water is acidic or alkaline. Our pH meters use a specialized electrode to measure the pH of water, which is typically displayed on a digital screen or readout.
  • Determine water quality: pH is an important indicator of water quality, as it can affect the solubility and toxicity of various chemicals and metals in water. By measuring the pH of water with GAO water pH meters, we can help determine whether water is suitable for various uses, such as drinking, irrigation, or industrial processes.
  • Monitor water treatment: Our water pH meters are used to monitor the pH of water during water treatment processes, such as chlorination, coagulation, and sedimentation. By monitoring the pH of water, operators can ensure that the treatment process is effective and that the water is safe for its intended use.
  • Maintain equipment: pH can affect the performance and lifespan of various equipment and machinery that use water. By monitoring the pH of water with our water pH meters, operators can prevent corrosion, scaling, and other issues that can damage equipment and decrease efficiency.

GAO’s water pH meters are rugged, portable, versatile and precision measurement instruments. They comply with applicable industry standards such as ISO 9001, ASTM E70, good laboratory practice/good manufacturing practice (GLP/GMP), food and drug administration (FDA) regulations, and CE certification.

Our water pH meters help our clients in complying with relevant U.S. government regulations such as:

  • Clean Water Act
  • Safe Drinking Water Act
  • Occupational Safety and Health Administration (OSHA) regulations
  • Environmental Protection Agency (EPA) regulations
  • Food and Drug Administration (FDA) regulations

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

  • Canadian Environmental Protection Act
  • Canadian Drinking Water Guidelines
  • Canadian Environmental Quality Guidelines
  • Occupational Health and Safety Regulations

GAO’s water pH meters have the following applications:

  • Water treatment: GAO pH meters are used to monitor the pH levels in water treatment plants to ensure that the water is safe for consumption.
  • Aquaculture: Our pH meters are used to monitor the pH levels in fish tanks, ponds, and other aquatic systems to ensure that the water conditions are suitable for fish and other aquatic organisms.
  • Agriculture: Our pH meters are used to measure the pH levels of soil and irrigation water in agriculture to optimize crop growth.
  • Environmental monitoring: GAO pH meters are used to monitor the pH levels of natural bodies of water, such as lakes, rivers, and oceans, to detect and prevent water pollution.2
  • Scientific research: Our pH meters are used in scientific research to measure the pH of various solutions in chemistry, biochemistry, and other scientific fields.
  • Food and beverage industry: Our pH meters are used to monitor the pH levels in food and beverage production processes to ensure product quality and safety.

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