This turbidometry - 120 D is specially designed for testing the low turbidity levels. Ensuring complete accuracy, this can read either in standard NTU units by calibrating with NTU standard solution as described later, or in PPM units by calibrating with solutions standardized gravimetrically, as per user's choice. The calibration can be adjusted with the CAL Control on the front panel. This auto ranging instrument is available in four ranges such as:

Basic Range	0-1.9999 NTU/PPM Units
Second Range	0-19.999 NTU/PPM Units
Third Range	0-199.99NTU/PPM Units
Final Range	0-1999.9 NTU/PPM Units
