0.01–9999.9 nephelometric turbidity units (NTU)
± 5% of reading or ± 0.1 NTU (whichever is greater) from 0.01 to 2000 NTU;
± 10% of reading from 2000 to 9999 NTU
0.01 NTU up to 999.99 NTU; 0.1 NTU from 1000.0 to 9999.9 NTU
Better than ± 1.0% of reading or ± 0.04 NTU, whichever is greater for each range.
Initial response in 45 seconds
1.0 to 2.0 L/min (0.3 to 0.5 gal/min) (15 to 30 gal/hr)
–20 to 80 °C (–4 to 140 °F); 95% relative humidity, non-condensing.
sc100: 0 to 50 °C (32 to 122 °F) for one SS7 sc on an sc100; 0 to 40 °C (32 to 104 ° F) for one

Formazin – user-prepared primary or wet calibration of the instrument
Standardization plates with approximate values of 100 or 1000 NTU. Unique value is assigned
when dry verification is done immediately after calibration and is used with pass/fail criteria for
subsequent verifications.
Mandatory before calibration
Optional before verification
Mandatory upon verification failure
