Lovibond PTV 1000 online turbidity analyser

Continuous low-level turbidity measurement for drinking water, with configuration advice and practical support from PMA.

Confidence in every reading.

Reliable low-level measurement starts with a representative sample. Stable flow, effective bubble control and an accessible sample path help operators follow changes in drinking-water turbidity while keeping routine checks and cleaning manageable.

Calibration and verification provide a practical way to check instrument performance over time. PMA can help you plan the sample connection, choose the appropriate configuration and establish an installation and maintenance routine that suits your site.

The Lovibond PTV 1000 is an online turbidity analyser for continuous low-level drinking-water measurement. Also called a process turbidimeter or online turbidity meter, it monitors a flowing sample rather than an occasional bottle sample.

A compact flow body, integrated bubble trap and guided interface help operators manage the measurement from installation through to calibration and maintenance.

Find the right configuration.

PMA can help you select the optical configuration and installation approach for your water quality monitoring requirements.

PTV 1000

Small details that support reliable results

Manage bubbles

The integrated, patented bubble trap reduces bubble interference while keeping the flow path accessible for cleaning.

Control stray light

An internal light dump captures stray light to support measurement reproducibility at low turbidity levels.

Respond to changes

The small-volume flow body helps water move through the instrument quickly, supporting a responsive measurement and easier cleaning.

A simpler routine, from standard to result

T-CALplus primary calibration

T-CAL stabilised formazin standards in T-CALplus packaging provide a sealed approach to calibration, reducing direct handling and helping to avoid spills.

  • Sealed packaging for controlled handling
  • Mix and dispense using the squeeze pack
  • Vacuum-sealed packaging helps limit bubbles
  • Interactive guidance through the calibration process

Dry-block verification

Secondary solid verification standards provide a practical way to check instrument performance between calibrations.

The video guide explains how to assign a value to the verification block. The high-level block is demonstrated; the same baseline procedure applies to the low-level block.

“We have installed 3 demonstration units and each installation was a breeze that delivered excellent data. You can immediately tell it is a better measurement than the older technology by the lower reading it provides. The patented light dump does an excellent job of eliminating stray light.”

Lovibond Tintometer

Lovibond Tintometer supplies water analysis equipment for leisure, environmental and industrial applications. Speak to PMA about selecting and supporting the right instrument for your site.

A configuration that matches your method

The PTV 1000 is available with different optics. Specify the actual model and measurement method rather than treating every PTV instrument as interchangeable.

Infrared option

The PTV 1000 IR uses infrared nephelometric measurement associated with ISO 7027 and FNU reporting. Confirm the method required by your site.

White-light option

The PTV 1000 WL uses white-light LED measurement and NTU reporting. The documented US drinking-water method applies to this optical model; it is not a blanket approval for every configuration.

Sample and installation

Assess representative sampling, stable flow, drainage and access for cleaning. Long sample lines, entrained air or deposits can affect the result seen by the instrument.

Communications and support

Select the appropriate power, output and communications arrangement for your control system. Interfaces and app functions depend on the supplied configuration.

Questions about this measurement

Is a turbidity analyser the same as a turbidimeter?

These terms, including the US spelling “turbidity analyzer”, commonly describe instruments that measure turbidity. The PTV 1000 is a continuous online process instrument; a portable meter serves a different sampling workflow.

Where does the PTV 1000 fit in drinking-water treatment?

Its low-level design suits filtered and treated drinking water. A filter-effluent application needs a representative sample and a stable installation as well as the correct instrument. Discuss other water matrices with PMA before selecting a model.

Can NTU and FNU results be assumed to be identical?

The units reflect different optical methods. Instruments may agree on a calibration standard while responding differently to real water samples. Keep the method, optical model and units clear when comparing data.

Does dry-block verification replace calibration?

No. Calibration establishes the instrument response using the specified primary standard. Dry-block verification checks performance against an assigned reference; it does not replace the wet calibration procedure.
