Calibration Range
The test kit is supplied with four vials of high-molecular polymer turbidity standard solutions, providing a comprehensive calibration range:
- 0.02 NTU: A low concentration standard for precise calibration at the lower end of the turbidity scale.
- 20.0 NTU: An intermediate concentration standard suitable for mid-range calibration.
- 100 NTU: A higher concentration standard for calibration in the upper range of turbidity measurements.
- 800 NTU: A very high concentration standard for calibrating turbidity sensors at the extreme upper end of the scale.
Key features of these standards include:
- EPA Approved. The standards are approved by the U.S. Environmental Protection Agency (EPA) as primary calibration standards for turbidity sensors used in drinking water analysis.
- Safe and Non-Toxic. The solutions, which are high-molecular polymer turbidities, ensure health and safety standards by being safe and non-toxic.
- Disposable. The standards are disposable, eliminating the need for complex handling and storage procedures.
- NIST Traceable. The standards are NIST (National Institute of Standards and Technology) traceable, providing a reliable reference for particle size/distribution and optical density.
- Inherent Stability. The standards exhibit inherent stability, preventing settling from suspension and maintaining accuracy over time.
- Extended Shelf Life. The one-year shelf life of the standards is guaranteed, allowing flexibility in usage even if a bottle is not recapped tightly after opening.
These high-quality turbidity standards make calibration processes convenient, reliable, and compliant with regulatory standards, making them an essential component of the turbidity test kit.
