A colorimeter is a light-sensing instrument that measures how light is absorbed and transmitted as it moves through a liquid sample.
Colorimeters follow the principles of the Beer-Lambert Law (Beer’s Law), which is the linear relationship between absorbance and concentration.
To analyze a specific analyte in a liquid sample, color-forming reagents are added. The color reaction is proportional to the concentration of the analyte.
High concentrations will absorb more of the light than a solution with a diluted concentration.
Hach’s easy-to-use, robust, portable colorimeters are built to handle the unique stresses present in testing water quality.
Whether you are looking for a single-parameter testing device, or sophisticated multiparameter handheld colorimeters, Hach has a solution that will support your needs, with quality reagents and simple testing procedures.

Portable analysis can be difficult in the field and requires instruments designed to withstand field conditions. A pocket colorimeter offers reliable, accurate results in a simple, ergonomic design.
The Hach DR300 is a single-parameter colorimeter with several different parameter-specific versions available. Hundreds of thousands of water professionals trust the DR300 pocket colorimeter in harsh conditions in the field.
Multiparameter handheld colorimeters are for water quality professionals who test numerous colorimetric parameters in harsh, demanding environments.
The Hach DR900 portable colorimeter allows for quick and easy access to your most frequently used testing methods in as little as two clicks.
This colorimeter is waterproof, dustproof and shock-resistant, and has been drop tested for greater quality assurance. It offers an intuitive user interface, large data storage and a built-in USB port for the easy transfer of information.
The ultimate suite of field-ready handheld instruments from Hach combines Chemkey colorimetric testing and probe-based analyses into a single, portable instrument.
The SL250 and SL1000 multiparameter water quality meters allow for tests to be conducted in parallel—saving time, reducing variability, and with less hassle than traditional analyses.
