Hach DR300 Pocket Colorimeter

How do you make the best portable colorimeter on the market? Start with the tried and true Hach Pocket Colorimeter II – one that has been used by hundreds of thousands of water professionals in harsh conditions for almost two decades – and make key mechanical improvements: upgraded waterproofing; larger display; ergonomic design. Then infuse it with the smart capabilities that modern technology has to offer: optional Bluetooth connectivity with automatic data transfer, and seamless system integration*. The result is the Hach DR300 Pocket Colorimeter, the next generation in portable instrumentation. Reduce data collection hassles, eliminate transcription errors, and ensure stronger compliance traceability.

  • Single Parameter go-anywhere portable photometer
  • Battery operation for a maximum of 5000 tests
  • Waterproof instrument IP67 (even better than PCII)
  • Larger, better display
  • Data connectivity. Bluetooth to Claros*

* Bluetooth connectivity currently available only in US, Canada and EU.

DR300 Pocket Colorimeters are NOT sold with chemical reagents. Reagents must be purchased separately.

This instrument connects to Claros, Hach’s innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations. To unlock the full potential of Claros, insist on Claros Enabled instruments.

The DR300 maintains the Pocket Colorimeter legacy of reliability while providing state-of-the-art data transfer capability and connection to Claros*. Reduce data collection hassles, eliminate transcription errors, and ensure stronger compliance traceability.
