Our environmental testers have the following functions:

  • Air Quality Testers: Our environmental testers measure and monitor the quality of indoor and outdoor air, detecting pollutants such as particulate matter (PM), volatile organic compounds (VOCs), carbon monoxide (CO), and nitrogen dioxide (NO2). They help assess air pollution levels and provide information for improving air quality.
  • Water Quality Testers: GAO’s environmental testers analyze the quality and safety of water sources, including drinking water, lakes, rivers, and swimming pools. They measure parameters like pH, turbidity, dissolved oxygen, chlorine levels, and the presence of contaminants such as heavy metals, bacteria, and pesticides.
  • Soil Testers: Our environmental testers measure parameters like pH, nutrient levels (nitrogen, phosphorus, and potassium), moisture content, and organic matter content. Some testers can also identify soil contaminants.
  • Radiation Detectors: GAO Tek’s environmental testers measure and monitor radiation levels in the environment. They are used in fields such as nuclear power plants, healthcare, research, and emergency response. Radiation detectors help ensure safety and compliance with radiation protection standards.
  • Noise Meters: Our environmental testers are used to assess and monitor noise pollution levels in various settings, such as workplaces, construction sites, and residential areas. This information helps identify potential health risks and supports noise control measures.

Gao Tek’s environmental testers are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as ISO 17025, ISO 9001, ISO 14644, ASTM D5116, IEC 62471, IEC 61646, IEC 61730, and NIOSH 0600.

Our environmental testers help our customers comply with relevant U.S. government regulations such as:

  • Occupational Safety and Health Administration (OSHA) regulations
  • Environmental Protection Agency (EPA) regulations
  • National Institute for Occupational Safety and Health (NIOSH) regulations
  • Food and Drug Administration (FDA) regulations
  • Federal Communications Commission (FCC) regulations

Our environmental testers help our clients in complying with relevant Canadian government regulations such as:

  • Canadian Environmental Protection Act (CEPA)
  • Hazardous Products Act (HPA)
  • Workplace Hazardous Materials Information System (WHMIS)
  • Canadian Standards Association (CSA) standards
  • Health Canada regulations

Our environmental testers have the following applications:

  • Environmental Monitoring: Our environmental testers enable us to monitor and assess various environmental parameters such as UV radiation levels, temperature fluctuations, and particle concentrations in the air. This data helps in evaluating air quality, ensuring compliance with safety standards, and identifying potential hazards or pollution sources.
  • Industrial Quality Control: GAO’s environmental testers are used in industrial settings, allowing us to measure and control environmental factors that can impact product quality and production processes. For instance, our thermocouple thermometers ensure precise temperature monitoring for quality control in manufacturing or laboratory environments.
  • Agriculture and Horticulture: Our environmental testers, such as pH meters and conductivity meters, find applications in agriculture and horticulture for monitoring soil pH levels and measuring the nutrient concentration in irrigation solutions. This enables farmers and gardeners to optimize crop growth and ensure proper plant nutrition.
  • Research and Development: GAO’s environmental testers are valuable tools for researchers and scientists. They assist us in collecting accurate data related to UV radiation, temperature, and particle counts, aiding in the development of new technologies, understanding environmental phenomena, and conducting scientific experiments.

Our environmental testers can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
