Hach DR300 Pocket Colorimeter

Overview

The Hach DR300 Pocket Colorimeter is a compact instrument for on-the-go water-quality testing. Each model is dedicated to a single, specific parameter and comes with pre-programmed Hach methods, delivering accurate, reliable results without complex setup. Its small size makes it ideal for spot checks in the field or at the point of use.

An LED light source and silicon photodiode detector give dependable colorimetric readings, while a backlit LCD keeps results clear in low light. The DR300 is IP67 waterproof — protected at 1 m for 30 minutes — stores the last 50 measurements, and runs for roughly 5000 tests on four AAA batteries.
