Portable Turbidity Meter

The Portable Field Kit Model 11520 (battery and AC) has been designed and rigorously tested to meet all EPA standards for turbidimetric water testing. Incorporates a triple photo diode detection system that gives stable, reliable readings down to 0.02 NTU with 0.001 NTU resolution. The precision lamp, with built-in lens, requires no alignment and will operate continuously for more than 5,000 hours — over 7 months at 24 hours a day. Included with the meter: 0.5 NTU secondary standard, 10 NTU secondary standard, 0.5 NTU primary standard (60 ml), 10 NTU primary standard (60 ml), light shield, two optically-selected sample vials, and a rugged carrying case.
