Balanced Cell Photo Colorimeter-511

Balanced Cell Photo Colorimeter â 511 measure the absorbance of any solution in the range of 0-1000 KLETT units 3 ½ digit seven segment red LED display. This scale is proportional to the concentration of the solution under test. It is very easy to operate and trouble-free instrument. Concentration of the sample can be directly measured with reference to standard solution. This instrument is ideally suitable for all soil testing lab, fertilizer plants etc.
