Reliable, low-range turbidity
measurement
A new Turbidity Monitor designed to meet the needs of both municipal drinking water systems and industrial water treatment for reliable, low-range turbidity measurement
Analytical Technology introduces the new A15/76 Turbidity Monitor, designed to meet the needs of both municipal drinking water systems and industrial water treatment for reliable, low-range turbidity measurement Turbidity is the general indicator of the optical clarity of water, and can be defined as the amount of light scattered from particles in solution

By using an infrared light source and a 90 degree scatter measurement, the innovative A15/76 provides high sensitivity measurement with unmatched zero stability.
Providing a display of turbidity over a variety of operating ranges, the A15/76 monitor allows turbidity to be measured from as low as 0.001 NTU to as high as 4000 NTU, eliminating the need for separate high and low range instruments,.
The minimum display range of 0-4 NTU provides resolution down to 0.001 NTU and is suitable for almost any final filter monitoring application.
Ranges of 0-40 or 0-400 NTU are available for raw water or clarifier effluent monitoring, and a 0-4000 NTU range can be used for very high turbidity applications such as river water monitoring.
Because air bubbles are often a common problem in many turbidity systems, the ATi turbidity monitor has been designed to operate under pressure, eliminating the sample degassing that often causes air bubble errors.
Sample pressure is not dropped until the sample exits the measuring chamber, resulting in more reliable measurements.
In addition, the new turbidity monitor provides a sensor diagnostic function to warn of conditions that cause inaccurate or invalid readings.
The sensor is continuously monitored for optical fouling and will display an alarm message when the sensor requires cleaning.
Due to the fact that turbidity measurement is often required in waste water effluents, and other applications where sensor fouling can be a major problem, ATi also offers a special turbidity unit, the D15/76 system.
The D15/76 system uses an "air blast" sensor cleaning system that automatically cleans the sensor as often as necessary to maintain reliable measurements.
