TURBIDITY TEST SET.
Turbidity is a measurement of undissolved solids suspended in a liquid. A nephelometer emits a light beam into a liquid
sample and measures the amount of light reflected from undissolved solids. This measurement is automatically compared
to a stored measurement, usually taken from a known reference sample, and the difference is displayed by the meter in
Nephelometric Turbidity Units (NTU).
A probe is "zeroed" by immersing in a reference standard solution and activating the meter. The probe is then immersed
into the water being tested. Reading is given in Nephelometric Turbidity Units (NTU) on a digital display.
