How did we make the best portable colorimeter on the market with the DR300?
We started with the tried-and-true Hach Pocket Colorimeter II – used by hundreds of thousands of water professionals in harsh conditions for almost two decades.
We then made the following key improvements:
• Upgraded waterproofing
• Larger display (with backlight)
• Ergonomic design
Finally, we infused the instrument with the smart capabilities that modern technology has to offer – specifically optional Bluetooth connectivity with automatic data transfer and seamless system integration.
Other Key Benefits:
• Single Parameter go-anywhere portable photometer
• Compact design fits in your pocket
• Battery operation for a maximum of 5000 tests
• Rugged waterproof (IP67) design – withstands drops, extreme temperatures
• Store and recall up to 50 measurements
