GAO Tek’s environmental refractometers meters have the following functions:

• Determination of parameters: GAO’s environmental refractometers can help determine various parameters such as salinity in water bodies, the concentration of dissolved solids in soil or plant sap, or quality control of beverages and industrial fluids.
• Portable and rapid analysis: Our environmental refractometers are handheld devices that allow for on-site or field measurements, providing quick and convenient analysis without the need for complex laboratory equipment.
• Quality control and monitoring: GAO’s environmental refractometers are utilized to ensure quality control in various industries, including food and beverage production, agriculture, environmental monitoring, and chemical manufacturing, by monitoring specific parameters and ensuring consistency and compliance.
• Temperature compensation: Our environmental refractometers incorporate temperature compensation mechanisms to account for temperature variations and provide accurate measurements regardless of temperature fluctuations.
• Measurement of refractive index: Our environmental refractometers measure the refractive index of a liquid sample, which provides information about its composition or concentration.

GAO’s environmental refractometers are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as ASTM (American Society for Testing and Materials) E1269-11, USP (United states pharmacopeia) general chapter<781>, AOAC (association of official analytical chemists) official method 934.01, and ISO 5725-1:1994.

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

• Good Manufacturing Practices (GMPs)
• Occupational Safety and Health Administration (OSHA)
• Environmental Protection Agency (EPA)
• National Institute of Standards and Technology (NIST)

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

• Canadian Food Inspection Agency (CFIA)
• Health Canada
• Environment and Climate Change Canada (ECCC)
• Canadian General Standards Board (CGSB)
• Canadian Centre for Occupation Health and Safety (CCHOS)

GAO’s environmental refractometers have the following applications:

• Chemical and Pharmaceutical Industry: GAO’s environmental refractometers are used in the chemical and pharmaceutical industries to determine the purity of substances. The refractive index of a substance is related to its purity, so by measuring the refractive index, the purity of a substance can be assessed. This information is important for quality control purposes and for ensuring that the substance meets specific standards.
• Petroleum Industry: Our environmental refractometers are used in the petroleum industry to determine the quality of fuels and lubricants. The refractive index of a substance is related to its density, which is an important parameter for determining the quality of petroleum products. They can also be used to detect the presence of water or other impurities in petroleum products.
• Gemstone Industry: GAO’s environmental refractometers are used in the gemstone industry to determine the authenticity of gemstones. Each gemstone has a unique refractive index, so by measuring the refractive index, the authenticity of a gemstone can be verified. Refractometers are also used to determine the quality and value of gemstones.
• Veterinary Medicine: Our environmental refractometers are used in veterinary medicine to measure the concentration of various substances in animal body fluids, such as blood and urine. This information is important for diagnosing and monitoring various health conditions in animals.
• Agriculture: Our environmental refractometers are used in agriculture to measure the sugar content in fruits and vegetables. This information is used to determine the optimal time for harvesting crops and for ensuring the quality of the final product.

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