HI-2640 Dissolved Oxygen Benchtop Meter

HI-2640 Dissolved Oxygen Benchtop Meter

HI-2640 benchtop meter enables fast, accurate measurements utilising the Hanna Instruments digital electrode / probe for HI-764080 dissolved oxygen. Each digital electrode / probe has a unique serial number and the parameter that it measures is automatically identified by the meter.

Once connected, the single sensor or sensors are ready to measure the parameter along with temperature. The HI-2640 measures dissolved oxygen in ppm and % saturation.

The intuitive design simplifies configuration, calibration, measurement.

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

Key Features:

• Automatic parameter recognition
• DO choice of measurement unit: ppm (mg/L), % saturation
• Basic mode for simplified operation
• Dedicated GLP key
• Internal clock and date
• Atmospheric pressure sensor in probe

Digital probe input - simply connect each probe via the 3.5 mm jack, Digital Smart Electrodes are automatically recognised.

Clear, full text readout - The HI-2640 presents clear, detailed text prompts at the bottom section of the screen.

Atmospheric pressure sensor - To make measurements the most accurate, the dissolved oxygen digital probe used with HI-2640 features an atmospheric pressure sensor for automatic pressure compensation.

GLP - The sensor retains data from the most recent calibration, including date, time, and standards utilised.

Capacitive touch keypad - HI-2640 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 - HI-2640 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 130° viewing angle, provides one of the easiest to read LCDs in the industry.
