HANNA HI-2600 Series Dissolved Oxygen Bench Meter

HI-2640 Dissolved Oxygen (DO) Benchtop Meter

The HI-2640 Dissolved Oxygen Benchtop Meter provides fast, accurate measurements of dissolved oxygen (DO) and temperature using the Hanna Instruments HI-764080 digital DO electrode/probe. Each digital probe features a unique serial number, allowing the meter to automatically recognize the parameter being measured, simplifying setup and reducing errors.

The HI-2640 measures dissolved oxygen in ppm and % saturation, making it ideal for laboratories, research facilities, educational environments, and industrial applications. Its intuitive design streamlines configuration, calibration, and measurement, ensuring reliable and repeatable results.

Featuring a large 5.5” (14 cm) LCD display with capacitive touch keys and a 130° wide viewing angle, the HI-2640 offers clear visibility and user-friendly operation, even in busy laboratory environments.
