optek Turbidity Measurement
Turbidity is an optical characteristic of a liquid or transparent solid sample, which in general describes the clarity or haziness of the sample. In the past human eyes “measured” the turbidity in comparison to visual turbidity scales or by “experience”. Today’s industrial measurement of clarity or haze is automated and reproducible wherever the measurement is performed – eliminating any human influence.

Turbidity Low Range
TF16-N Turbidity Meter
High Performance Dual Channel Turbidity Meter
The TF16-N is a high precision turbidity meter for installation into pipelines measuring scattered and unscattered light at two independent angles in various liquid process streams. The ratio of scattered to un-scattered light can then be correlated.
Used For
- Precise control of turbidity
- Turbidity scales
- CU (concentration units)
- ppm (DE)
- FTU (ISO)
- FAU
- EBC
- Lauter tun / mash filter control
- Turbidity measurement angle 0°, 11°
TF56-N Turbidity Sensor
Dual Channel Turbidity Sensor
The TF56-N sensor is an inline real-time device designed to measure light absorbance at 11° caused by interaction with process turbidity. As an NIR light beam is passed through a dynamic process stream, the sensor simultaneously measures the amount of light scattered at 11° and the remaining amount of un-scattered light at 0°.
Used For
- Turbidity scales:
- ppm (DE)
- FTU (ISO)
- EBC
- Turbidity monitoring
- in filter control
- of condensate
- for separator control (food & beverage)
- Lauter tun / mash filter control
- Turbidity measurement angle 0°, 11°
