The common issues operators face using a turbidimeter include instrument maintenance, bubbles in the sample and exposure to chemicals. To find a solution to these challenges, Lovibond® Tintometer® assembled a team of globally recognised turbidity and process instrumentation experts who have created a user-inspired secure system with significantly reduced complexity.

The process of turbidity monitoring is necessary under the Australian Drinking Water Guidelines to ensure that filtration is optimal and produces safe drinking water. Turbidimeters are used to review short-term performance of filtration as well as monitoring their long-term effectiveness over months and years under a full range of challenges.

The turbidimeter has evolved slowly over its life span with the process remaining largely unchanged and complex. Operators encounter the same problems including excessive instrument maintenance to ensure read accuracy, bubbles in the sample compromising the turbidity reading and the handling and exposure of chemicals in the standards.

These issues, if not controlled, can affect the accuracy of the turbidimeter creating false data.

With these issues in mind, the team of experts produced a solution that carefully considers 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.

User-inspired design

Unlike traditional turbidmeters, the PTV Series requires little maintenance. Focused on simplicity, the PTV series eliminates the need to change light sources regularly and has a thoughtful, easy to clean design.

The body has been optimally designed to provide faster response to turbidity spikes due to its low volume flow; the optimal flow rate of the instrument is 40 to 80ml per minute. This uses far less water which, over the lifetime of the instrument, translates to over three million litres of water saved per instrument versus competitive instruments.

The smarter way to control

The PTV 1000 and PTV 2000 allow two ways for operators to interact with the instrument. They have the option to use the integrated touchscreen interface on the unit itself that is able to perform all functions. Or operators can interact with an unlimited number of turbidity sensors using an app installed on a smartphone or tablet.

The AquaLXP app eliminates the need for dedicated controllers for each instrument which allows for maximum flexibility with changing regulatory requirements and operator needs.

A record of every reading, calibration, verification, cleaning or other maintenance performed over the lifetime of the sensor is automatically logged into the instrument history. The AquaLXP app makes it easy to extract and analyse data such as upper and lower control limits and percent compliance over a selected time frame which can be viewed as a table or graph.

For added security, the app is password protected and only operators within a certain physical proximity of the PTV sensor can connect to it assuring data integrity.

With the PTV series ability to easily interface, export and analyse data, getting accurate turbidity readings has never been easier.
