PTV 2000 with flow indicator and Modbus

Process Turbidity Simplified

  • Optimized for municipal drinking water monitoring 
  • Low maintenance design saves operator's time
  • EPA & ISO options for regulatory compliance
  • Low volume flow body detects changes in turbidity fast

Details Matter. The development of the PTV Series considered every aspect of process turbidity workflow - from installation and setup; daily measurement and control; routine procedures such as calibration, verification and maintenance; to data collection and management. 

The PTV Series is optimized for monitoring filter effluent in a regulatory environment.  By focusing on helping operators manage routine workflows, the instruments deliver an easy to use system with unsurpassed accuracy when monitoring low levels of turbidity.  

Every instrument has an integrated touchscreen display, which makes it easy to see current turbidity values and to assess the status of the instrument.  Outputs and alarm status are always clearly visible, and can alert operators to an issue.   

The flow body is easy to clean - there are no “nooks and crannies” where particles can settle. The body can be easily drained for cleanings or calibrations with quick-connect fixtures and collecting a grab sample for verification does not require the operator to disconnect tubing to access the sample.  The low volume flow body allows changes in turbidity levels to be seen faster than competitive instruments.  

All models feature a solid state light source which means there are no bulbs to change over the life of the instrument.  The optical design has eliminated the chance for condensation and fogging, without the use of desiccants, and there is no risk of fouling the optical system with the presence of iron and manganese.  

The PTV Series also makes it easier than ever to access and analyze data.  Every logged reading, calibration and verification associated with a measurement module over its lifetime is stored locally, ensuring proof of routine data is never deleted or unavailable.  Operators are able to access the information directly from the instrument, so there is no need to locate maintenance logs or pull the data from a SCADA system.

Product information

  • Process Simplified - A New Approach
    Details Matter. The development of the PTV Series considered every aspect of process turbidity workflow - from installation and setup; daily measurement and control; routine procedures such as calibration, verification and maintenance; to data collection and management.
  • Smart User Interface - Rethink the Controller
    We’ve replaced the need for a traditional controller with the familiar interface of a smart device. By utilizing a mobile device app, the user experience is enhanced by allowing quick and easy data viewing, calculation of statistics and access to operator instructions and useful tips.
  • Designed to Save
    Save time, money and water by using the PTV system. These instruments are optimized for drinking water applications with unsurpassed low range accuracy (below 1 NTU). It has a variety of features that help users save.
  • Regulatory Compliant
    The PTV Series has instruments that meet EPA and ISO regulatory requirements.
  • Fluidics Manager
    The Fluidics Manager is an additional accessory that streamlines sample flowing into and out of the instrument. This eliminates the need to install and maintain separate devices to control sample entering and exiting the sensor.  
  • Panel Mounting System
    A Place for Everything - The Panel Mount is an additional accessory that aids in the installation of key instrument components and accessories.
  • Two Ways to Interface
    Touchscreen Interface - All PTV Series instruments are supplied with an integrated touchscreen. All measurement settings and routine functions such as calibration can be managed directly with the touchscreen without the need for additional devices.
    AquaLXP™ Interface - The AquaLXPTM app is an enhanced version of the touchscreen. In addition to being able to perform all of the functions as the touchscreen, users have access to animated instructions of all procedures, advanced data analysis and statistics tools, complete maintenance and repair logs as well as the comfort of using a familiar device.
  • Wet Standards - for Calibration & Verification
    T-CAL Turbidity Standards from Lovibond® Tintometer® are primary standards that are US EPA and ISO compliant.  
    When you combine our T-CAL Turbidity Standards and our T-CALplus™ packaging, turbidity standards have never been easier to use.
