GAO’s environmental colorimeters typically have the following functions:

• Color measurement - The primary function of our environmental colorimeters is to measure the color of environmental samples, such as water or soil. This allows researchers and analysts to determine the presence or concentration of specific substances in the sample that may affect its color.
• Detection of contaminants - Changes in color can be indicative of the presence of contaminants or pollutants in the sample. GAO’s environmental colorimeters can help to detect these changes and identify the specific substances that may be present.
• Monitoring of water quality - Water quality is often assessed based on a range of factors, including color. Our environmental colorimeters can be used to monitor changes in water quality over time and identify potential sources of pollution or contamination.
• Research and analysis – Our environmental colorimeters are used in environmental research and analysis to help us understand the effects of pollutants and contaminants on natural ecosystems. By measuring changes in color, researchers can gain valuable insights into the health and function of these ecosystems.
• Regulatory compliance - GAO’s environmental colorimeters are used in regulatory compliance testing to ensure compliance with local, state, or federal regulations.

GAO’s environmental colorimeters are rugged, portable, versatile and precision measurement instruments. They comply with applicable industry standards such as ASTM D1209 standard test method for color of clear liquids (platinum-cobalt scale), EPA method 180.1, ISO 7887, AOAC official method 969.33, USP general chapter <851> spectrophotometry and light scattering.

Our environmental colorimeters help our clients in complying with relevant U.S. government regulations such as:

• Environmental Protection Agency (EPA) regulations
• Occupational Safety and Health Administration (OSHA) regulations
• Food and Drug Administration (FDA) regulations
• National Institute of Standards and Technology (NIST) regulations
• United States Pharmacopeia (USP) regulations

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

• Canadian Environmental Protection Act, 1999
• Safe Drinking Water Act (SDWA)
• Canadian Food and Drug Regulations
• Occupational Health and Safety Regulations
• Canadian General Standards Board (CGSB)

GAO’s environmental colorimeters have the following applications:

• Water quality monitoring - Our environmental colorimeters are used to monitor the color of water samples, as changes in color can indicate the presence of pollutants, contaminants, or other substances that may affect the quality of the water.
• Soil analysis – GAO’s environmental colorimeters can be used to measure the color of soil samples, which can help to identify the presence of specific minerals, organic matter, or contaminants that may affect the health of plants or other organisms.
• Environmental research – Our environmental colorimeters are used in research projects to help us understand the effects of pollutants, contaminants, or other substances on natural ecosystems.
• Regulatory compliance testing - GAO's environmental colorimeters are used to monitor compliance with environmental regulations, such as those governing the quality of drinking water or wastewater discharge.
• Industrial and manufacturing processes - Our environmental colorimeters can be used in industrial and manufacturing processes to monitor the color of raw materials or finished products and ensure that they meet specific quality standards.
• Food and beverage production- GAO’s environmental colorimeters can be used to measure the color of food and beverage products, which can affect their visual appeal, quality, and safety.

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