All about my business

The system for colorimetric water analysis
With its accessories, the Lovibond® Comparator system 2000 is an extremely versatile, modular system for testing water. It is simple to use yet is uncompromising in terms of precision and reproducibility of results. It is compact and portable. The integrated prism brings the glass standards of the test discs and the coloured sample into the same field of view.

Test discs
The required accuracy of results is only ensured if stable, fade-free colour standards are used. Glass colour standards are fade-free, resistant to chemicals and scratchproof. Lovibond® standards are made from coloured glass filters. They comply with international standards, e.g. ISO 7393/2.

Lighting unit
We recommend the use of the battery-operated Lovibond® lighting unit in variable lighting conditions. This guarantees uniform lighting conditions, and ensures greater test accuracy
Cells
We manufacture precision plastic and optical glass cells in line with the highest quality standards. The cells ensure high precision and reproducibility of results.

Testpak – Ideal add-on for the Comparator 2000+
For the most popular tests, discs are available in a Lovibond® TESTPAK. The TESTPAK is a simple and cost-effective means of extending the use of an existing Comparator instrument to a new test parameter. Each TESTPAK contains the required test disc, tablet reagents (normally for 100 tests), cells and accessories as well as detailed instructions for the
desired method.

Test Kits – Complete kits for water analysis
Scope of delivery for standard kits Comparator test kits are supplied as a complete system in a sturdy plastic case. Together with the Comparator 2000+ and test discs, each kit includes all the necessary cells, accessories and Lovibond® tablet reagents (for 100 measurements) to achieve reliable results. The table to the right shows a selection of the most popular standard test kits. Customised equipment In addition to supplying standard test kits, we can construct customised kits to suit individual requirements. Based on the desired test parameters and measuring ranges we will draw up a detailed offer to suit your application.

Optional accessory
All test kit versions allow integration of the battery-operated portable lighting unit TK 102 and charger TK 102/ 1.

Operating instructions
The operating instructions provide a step-by-step explanation of how to conduct the water test, ensuring that even “non-chemists” can achieve reliable and accurate measurements in the minimum of time.
