The DR300 by Hach is a robust, portable single parameter colorimeter. It is the follow on from the Pocket colorimeter II which has been discontinued for most parameters – offering improved waterproofing, a large display and ergonomic design combined with optional Bluetooth and system integration. This unit is available in two formats – a single wavelength (either 500, 528, 600, 655nm) or pre-programmed with a single parameter test. You can view our range here.
