MEASUREMENT UNITS
Many methods were used to measure turbidity over the years. The Jackson Candle Turbidimeter was
used to measure turbidity as Jackson turbidity units (JTU). The Secchi Disk is commonly used to
measure turbidity in lakes and other deep waters (mg/L SiO

). Both methods are visual and are not
considered very accurate. To obtain more accurate readings a formazin based meter should be used
as a turbidity reading instrument.
The HI 98713 turbidimeter reports the measurements only in FTU (Formazin Turbidity Units).
