Turbidity Calibration Standards

Turbidity Calibration Standards Evaluated from a Different Perspective Formazin was established as the first calibration standard for turbidimeters in the 1950’s. Machine performance and USA Environmental Protection Agency (EPA) approval for turbidimeters was structured around formazin as the calibration standard. The EPA method 180.1 also outlined design parameters for turbidimeters used for testing surface source … Continue reading Turbidity Calibration Standards

Conversion of Nephelometric Turbidity Units

Conversion Relationship between Nephelometric Turbidity Units (NTU) into mg/l for Alberta Transportations’ Turbidity specification Conversion of Nephelometric Turbidity Units (NTU) into mg/l for Alberta Transportations turbidity specification is required since NTU is used as a surrogate for Total Suspended Solids (TSS) because it can be measured immediately in the field. NTU can then be converted … Continue reading Conversion of Nephelometric Turbidity Units
