DR900 Multiparameter Portable Colorimeter

Description

The Hach DR 900 is a handheld colorimeter that uses an LED light source. The device operates at wavelengths 420, 520, 560 and 610 nm and is used to measure various quality parameters of drinking water, waste water and industrial water. The instrument comes with a full set of stored programs (pre-installed and programmed methods), as well as provides the ability to store user programs and select favorites.

The device has one compartment for 25 mm round cuvettes, into which an adapter for 16 mm cuvettes can be installed.

The portable colorimeter provides quick and easy access to the most commonly used test methods in less than four clicks. The DR900 also simplifies basic analyzes by offering over 50 of the most common test parameters.

The instrument is equipped with an intuitive user interface, data storage for up to 500 tests and a built-in USB port for easy data transfer to a PC for further work with the results obtained. The improved user interface allows you to quickly select the analysis of the desired parameter.

The colorimeter is waterproof, dustproof, shockproof and drop tested for greater quality assurance. By combining all of these features with a push-button display and backlight for low-light use, you have a portable colorimeter that's ready to go and makes it easy to analyze water samples in any working condition.
