Comparator Test Kits
Simple, reliable visual testing for routine water analysis.
Lovibond® CHECKIT® Comparator Test Kits provide a practical solution for water quality monitoring across a wide range of industrial and commercial applications.
Using established visual colour comparison methods, the kits allow users to measure key water quality parameters quickly and easily without the need for electronic instrumentation.
Compact and portable, the range provides a convenient testing solution for on-site analysis, process monitoring and routine water quality checks.
Reliable Visual Testing
CHECKIT® Comparator Test Kits use a visual colour comparison method to determine the concentration of specific parameters within a water sample.
Following the addition of the appropriate reagent, the developed sample colour is compared against integrated colour standards to determine the result.
This established measurement method provides a practical alternative to electronic instrumentation for applications where portability, simplicity and ease of use are important.
A Range of Testing Options
CHECKIT® Comparator Test Kits are available for a wide range of water quality parameters, allowing users to select the testing capability appropriate to their application.
Each kit brings together the comparator, colour standards, reagents and accessories required to carry out the specified analysis in one convenient package.
This provides users with the equipment required to begin testing while keeping the individual components organised and readily available.
Designed for Efficient On-Site Testing
The compact, portable design of CHECKIT® Comparator Test Kits makes them particularly suited to testing directly at the sampling location.
With no electronic measurement system or power supply required, testing can be carried out across different sites and working environments using a simple visual procedure.
Clear test methods support consistent operation, helping users obtain dependable results as part of regular water monitoring programmes.
Practical for Routine Water Monitoring
CHECKIT® Comparator Test Kits are designed for regular use in applications where fast and accessible water testing is required.
Reagents, colour standards and testing accessories are kept together within the kit, making equipment easy to transport, store and access when required.
Replacement reagents are also available, allowing the comparator and colour standards to remain in regular use as part of an ongoing testing programme.
Supporting Effective Water Quality Control
Regular testing helps operators monitor changing water conditions and identify when adjustments to treatment or operating processes may be required.
By combining established visual measurement methods with portable equipment, CHECKIT® Comparator Test Kits provide an accessible way to carry out routine checks without the additional requirements of electronic instrumentation.
This makes the range a practical solution for maintaining regular water quality monitoring across field, industrial and commercial applications.
