Turbidity Measurement
An internal turbidity/color measurement unit measures sample turbidity using transmitted and
scattered lights.
Light of 635 nm is irradiated on the sample in the cylindrical cell and turbidity is calculated using
the formula below.
T: Turbidity
Ss: Scattered light of sample
Ts: Transmitted light of sample
Sw: Scattered light of washing solution
Tw: Transmitted light of washing solution
K: Factory-set instrument coefficient
Turbidity is determined by the obtained T value.
T range Turbidity Output
T < (Level 1)

(Level 1) ≤ T < (Level 2) Turbid 1+
(Level 2) ≤ T Densely turbid 2+
* (Level 1) and (Level 2) are constants.
