Handheld Colorimeters

Handheld colorimeters measure the amount of light that passes through a solution compared to the light that would pass through a pure solvent.
Available in both visual and photoelectric options, colorimeters can provide your test sample with clear and accurate results.
Colorimeters have different sample compartments and are available in multiple forms. Some chlorine meters have different cuvette sizes to accommodate varying sample volumes.
Other available colorimeters carry user-friendly interfaces. Some advanced colorimeter options can also store measurement data for later analysis.
Benefit from easy-to-use features, including digital displays and controls for setting parameters such as wavelength and concentration units.

What is a chlorine meter?

A chlorine meter is a device used to measure chlorine concentration in water. Chlorine meters are commonly used in water treatment facilities, pools, laboratories, and environmental testing to monitor chlorine levels for safety and compliance. They provide accurate readings of free chlorine, total chlorine, or both, ensuring that water is safe for human use or consumption. Chlorine meters use various detection methods, such as colorimetry or electrochemical sensors, to deliver quick and reliable measurements, helping maintain appropriate disinfection levels and water quality.
