Water Quality Testers

GAO’s water quality testers are devices that are used to analyze the physical, chemical, and biological properties of water to determine its quality. These testers measure various parameters such as pH, Dissolved Oxygen, temperature, turbidity, total dissolved solids, and other factors that can affect the quality of water. Our water quality testers are used for ensuring that water is safe for consumption, as well as for environmental monitoring and research. They are used in a wide range of settings, including laboratories, water treatment plants, and field sites. There are many different types of water quality testers, ranging from simple handheld devices to complex laboratory equipment.

GAO’s water quality testers are composed of sensor or probe, display, data storage, power source, and calibration solutions.

The other common names of water quality testers are water quality monitors, water quality analyzers, water quality meters, environmental sensors, water testing devices, hydrometric instruments, water parameter testers, aquatic quality probes, water pollution detectors, liquid quality sensors, water chemistry analyzers, aquatic environment analyzers, water contaminant testers, hydrological instruments, water purity testers, water testing equipment’s, water quality assessment tools, aquatic health monitors, water analysis devices and water quality assessment instruments.

GAO Tek has been focused on servicing the North American markets and has earned praise from many of its customers in the U.S., Canada, and Mexico.

GAO’s water quality testers have the following functions:

  • Measuring water quality parameters: GAO’s water quality testers are used to monitor the quality of drinking water to ensure that it meets the regulatory standards for safe consumption.
  • Monitoring changes in water quality: Our water quality testers can be used to monitor changes in water quality over time. This can help identify trends and patterns in water quality and detect any changes that may indicate pollution or other environmental problems.
  • Ensuring compliance with regulations: They are used by regulatory agencies to ensure that water meets specific quality standards. For example, drinking water treatment plants must test water for a variety of parameters to ensure that it is safe for consumption.
  • Identifying sources of pollution: GAO’s water quality testers can be used to identify sources of pollution in water, such as industrial discharges or agricultural runoff. By identifying these sources, measures can be taken to reduce or eliminate pollution and protect the environment.
  • Research and analysis: Our water quality testers are used in scientific research to study the effects of pollution on water quality, to develop new water treatment technologies, and to improve our understanding of the factors that affect water quality.

GAO’s water quality testers are often rugged, portable, versatile, and precision measurement instruments. They comply with applicable industry and government regulations such as ASTM International, EPA Standards, Safe Drinking Water Act (SDWA), NSF/ANSI 53, NSF/ANSI 58, and NSF/ANSI.
