Introduction:

High performance portable turbidity meter, 2 to 5 points calibration, selectable 4 turbidity units. The meter is suitable for process control and field use.

Unpacking Before unpacking, ensure that the current work environment meet following conditions.

Relative humidity is less than 80%

Ambient temperature is greater than 0C and less than 60C

No potential electromagnetic and ambient light interference

Operating Principles

 portable turbidimeter operates on the nephelometric principle of turbidity measurement and is designed to meet the criteria specified in ISO 7027.

The following figure shows basic optical system of the meter. It includes a light source and a detector to monitor the light scattered at 90 degree with respect to the incident beam.
