LaMotte SMART® 3 Portable Colorimeter for Field Water Testing (Chlorine, pH, Nutrients)

LaMotte SMART® 3 Colorimeter for on-site water analyses — Field and lab water analysis

This balance is made for water-treatment operators, pool technicians, and environmental users who need a portable instrument for checking chlorine or other water-quality parameters during routine testing, troubleshooting, or compliance work.

Intro: Fast, Accurate Water Analysis Anywhere

The compact SMART 3 Colorimeter delivers precise water testing results both in the lab and in the field. Its intuitive software allows analysts to choose from over 75 pre-set LaMotte reagent tests. The multi-LED optical system automatically selects the optimal wavelength for consistent readings, displayed on the large, backlit screen.

Flexible Measurement Options

Results are displayed directly in concentration units, as well as Absorbance and %T, with support for seven languages. Users can add up to 25 custom calibrations for unique reagent systems. Test factors can be arranged in any sequence, and the built-in data logger stores up to 500 date-stamped readings. A USB connection enables real-time data transfer to a computer.

The Smart R‑3 Colorimeter is used by water quality technicians, beverage producers, environmental laboratories, and pool maintenance professionals to measure the concentration of dissolved chemicals and color intensity in liquids. Colorimeters determine absorbance of specific wavelengths of light to quantify analyte levels, a technique frequently applied in drinking water testing, beverage color control, and environmental analysis, as described in industry resources on colorimetric water testing methods.

Professionals value the Smart R‑3 Colorimeter for its easy operation, rapid results, and reliable measurement repeatability that support routine quality control checks. Compared with manual or visual color comparison methods, digital colorimeters provide quantifiable data that improve accuracy and traceability in water chemistry analysis, beverage formulation, and environmental monitoring workflows.

QUICK TIP :

Tubes and colorimetry chamber Keep tubes clean and free of lint, fingerprints, dried spills, and scratches, especially in the central area. Scratched or heavily used tubes should be replaced. Always wash tubes inside and out with mild detergent and air dry inverted to prevent contamination. For more information, please see Instruction Manual / Quick Start Guide
