Principle
Nephelometric (Non Ratio)
Range 0.01 – 1100 NTU
1)
Resolution 0.01 – 9.99 NTU = 0.01 NTU
10.0 – 99.9 NTU = 0.1 NTU
100 – 1100 NTU = 1 NTU
Accuracy ± 2 % of reading, or ± 0.01 NTU, whichever is bigger, in the
range of 0.01 - 500 NTU ;
± 5 % of reading from 500 to 1100 NTU
Repeatability ± 1 % of reading or ± 0.01 NTU which ever is greater
Operation Acid and solvent resistant touch-sensitive keyboard with
integral beeper as acoustic indicator.
