Dissolved Oxygen Benchtop Meter with Datalogging – HI2641

HI2641 enables fast, accurate measurements utilizing the Hanna Instruments HI764080 digital dissolved oxygen probe with an integral temperature sensor. The probe has a unique serial number and, once connected, is automatically identified by the meter.

HI2641 measures dissolved oxygen in ppm and % saturation while adding data logging capabilities. The intuitive design simplifies configuration, calibration, measurement, data logging and transfer (to a USB thumb drive or computer).

HI2641 benchtop meter offers a Basic Mode that streamlines measurement configuration and is useful for routine applications. Additionally, HI2641 can be used in Standard Operating Mode, where all features and capabilities are enabled.

Large display with capacitive keys The meter features a 5.5” (14 cm) LCD display. The large display provides a 130° wide viewing angle.

Features in-depth

Digital probe input

Simply connect each probe via the 3.5 mm jack; Digital Smart Electrodes are automatically recognized.

Clear, full text readout

The HI2641 presents clear, detailed text prompts at the bottom section of the screen.

Two operating modes

HI2641 can be used in Standard or Basic Operating Modes. Standard Mode enables all features while Basic Mode displays a simplified screen and features — ideal for routine measurements.

Atmospheric pressure sensor

To make measurements the most accurate, the dissolved oxygen digital probe used with HI2641 features an atmospheric pressure sensor for automatic pressure compensation.

Data logging

HI2641 provides data storage capacity, up to 1000 log records. Each data set comprehensively includes readings, GLP information, as well as date and time stamps.

GLP (Good Laboratory Practice)

The sensor retains data from the most recent calibration, including the date, time, and standards utilized. This information is available in basic and standard modes and is also included with logged data.

Capacitive touch keypad

HI2641 features sensitive capacitive touch buttons for accurate keystrokes for navigating menus and screens. Since they are part of the screen, the buttons can never get clogged with sample residue.

Easy to read LCD

HI2641 features a 5.5” (14 cm) LCD display that you can clearly view from over 5 m (16.4’). The large display, with its wide 150° viewing angle, provides one of the easiest to read LCDs in the industry.

USB-C port for data transfer

The HI2641 features a streamlined USB-C port that facilitates transferring data to your computer.
