UNPACKING METER CONTENTS 

 
Before unpacking the meter and its contents, ensure that the working conditions meet the following conditions: 
 
1. Relative humidity is less than 80%. 
2. Ambient temperature is greater than °C and less than 60°C 
3. No potential electromagnetic interference. 
 

INCLUDED ACCESSORIES 

 
The KS-TB-100 portable turbidity meter includes; 
 
1. Glass sample vials  
2. Calibration standards 0, 10, 200 and 1000 NTU  
3.  Lint-free cloth  
4. 9V battery 
 

OPERATING PRINCIPLES 
 

The KS-TB-100 portable turbidity meter 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
