Hanna HI2004-03 edge dedicated DO – Meter only

Hanna HI2004-03 edge dedicated DO – Meter only

The Hanna HI2004-03 edge dedicated DO – Meter only is a professional-grade dissolved oxygen (DO) meter, offered in a “meter-only” configuration. Designed for flexibility and precision, it is ideal for laboratories, fieldwork, aquaculture, and environmental monitoring applications. Although this model does not include a DO probe, it is fully compatible with Hanna’s HI764080 digital DO probe and related accessories.

Features

Slim and Modern Design

• Ultra-thin body (only 12.7 mm thick) fits comfortably in hand or bench space.

• Large 5.5” LCD screen with a wide 150° viewing angle ensures visibility even from a distance.

Accurate and Adaptable DO Measurements

• Wide measurement range from 0.00 to 45.00 mg/L and 0.0 to 300.0% saturation.

• Automatic calibration at 0% and 100% saturation (using HI-7040L and atmospheric air).

• Temperature, salinity, and altitude compensation ensures reliability in variable conditions.

Efficient Data Logging

• Supports up to 1000 total logs, divided into:

  • Manual log-on-demand (up to 200)

  • Manual log-on-stability (up to 200)

  • Interval logging (up to 600 samples across 100 lots)

Practical Connectivity and Power

• Equipped with both a micro USB port (for charging and PC interface) and a standard USB port (for data storage).

• Features a rechargeable battery with up to 8 hours of continuous use for field flexibility.
