Turbidity MonitorTurbidity Monitor Q46T


ATI’s Model Q46T Turbidity Monitor is designed to meet the needs of both municipal drinking water systems and industrial water treatment for reliable, low-range turbidity measurement.

Turbidity is a general indicator of the optical clarity of water, and is defined as the amount of light scattered from particles in solution. In practice, a light beam is directed into a water sample and a photo detector measures the light scattered at 90-degrees to the incident light beam. While other scatter angles are possible, the 90-degree measurement angle has become the standard for turbidity measurement in most water systems. It is used as a relative indicator of the amount of suspended solids in solution, and is measured in virtually all drinking water systems. It is also used in industrial water treatment systems as an indicator of product water quality.  

Features and Benefits:

  • Power options include universal 100-240 VAC +/- 10%, or 12-24 VDC.
  • Expansion board to add a third 4-20 mA analog output or to add three additional non-isolated low power relays.
  • Wide range capability, with selectable ranges of 0-2.000, 0-20.00, 0-200.0 and 2000 NTU provide maximum application flexibility.
  • Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for turbidity and temperature.
  • Standard PID control function assignable to one analog output.
  • Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
  • Back-lit large LCD display provides clear visibility in any lighting condition. A scrolling second line on the display provides additional information and programming prompts.
  • System automatically checks for sensor fouling, “dry cell”, and external light interference.
  • NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
