ATI’s Model Q46/76 Turbidity Monitor is designed to meet the needs of both municipal drinking water systems and industrial water treatment for reliable, low-range turbidity measurement.Using either white light or an infrared energy source in this 90 degree scatter measurement, the system provides high sensitivity measurement with unmatched zero stability. Turbidity measurements down to 0.001 NTU or as high as 400 NTU can be measured with the same monitor, eliminating the need for separate high and low range instruments.
