Coulometric Karl Fischer Titrator


The revolutionary Cou-Lo Select is a compact, portable and easy to use coulometric Karl Fischer titrator.

  • Truly portable ,

  • Simple operation,

  • 3 power options,

  • Low drift cell,

  • ACE Control System

  • Unparalleled support



A revolution in water content determination

The Cou-Lo Select has been specifically designed for the needs of the crude oil and petrochemical industries. It is preprogrammed so it can deliver the results you need with minimal training costs. The operator can access a range of sample volumes, densities and weights by means of intuitive arrow cursor controls. Hard copies of results are provided by a built in printer

Specifically designed for outdoor use
The Cou-Lo Select has been specifically designed for easy operation outdoors, possible thanks to its low drift cell. These compact instruments come with a ruggedised carry case and can be transported with reagents already in the titration cell, ready for use immediately on arrival.
Mobility is further enhanced by some flexible power options, the Cou-Lo Select can be powered from the mains, by its own internal battery or by means of its car adapter.
The correct result, every time

At the heart of the Cou-Lo Select is GR Scientific's state of the art ACE Control System. The patent pending ACE Control System (Automatically Compensated Errors) guarantees that the electrolysis current produced and the count rate displayed are always correctly synchronized, regardless of changes to the electrolysis cell resistance.

Unparalleled support

At GR Scientific we pride ourselves on the quality of our support and we offer a selection of comprehensive support and service options. Every Cou-Lo Select comes with a two year guarantee and a full calibration certificate.
