The HI2640 Benchtop Meter for dissolved oxygen combines Hanna Instruments' years of expertise with advanced digital technology. The meter is the result of visionary design and world-class research and development, packaged in a streamlined housing that fits seamlessly into any modern laboratory.
Key features of the HI2640 Benchtop Meter for dissolved oxygen:
- DO measurements (ppm and % saturation) in basic mode
- Accuracy ±1.5% of the measurement or ±1 decimal place
- Automatic digital electrode recognition
- HI764080 dissolved oxygen electrode with wide range (0.00 to 45.00 mg/L (ppm); 0.0 to 300.0% saturation). With unique serial number for full traceability.
- Compensation for air pressure (from -500 to 4000 meters) and salinity (from 0 - 40 g/L)
- Integrated temperature measurement
- Automatic temperature compensation (from 0 to 50 °C)
- GLP data with date, time, calibration standards, air pressure, salinity
- Large 5.5-inch LCD screen with wide viewing angle
- Compact, space-saving design
While the HI2640 Benchtop Meter for dissolved oxygen offers a reliable solution for DO measurements in basic mode, the HI2641 Benchtop Meter for dissolved oxygen with data logging goes a step further with extensive data logging, a choice of two operating modes, and salinity measurements.
Intuitive interface
Both meters feature a large 5.5-inch LCD screen that is clearly readable from a distance of more than 5 meters. The capacitive buttons allow you to navigate menus and screens accurately, even while wearing gloves. Because the buttons are part of the screen, they can never become clogged with sample material. The basic mode offers simplified operation, displaying only the most important functions. This makes the HI2640 Benchtop Meter for dissolved oxygen ideal for routine measurements in laboratories, educational institutions, and quality control.
Compact without compromise
Weighing only 850 grams and featuring a compact design, you save valuable space on your workbench. This is achieved without compromising on advanced features: the sensor stores GLP data from the most recent calibration, including the date, time, and buffers used. The meter operates with automatic sensor recognition, ensuring electrodes are recognized as soon as they are connected via the 3.5 mm connector. Calibration data, sensor type, and serial number are displayed immediately. Integrated temperature measurement and direct signal processing ensure stable and noise-free measurement results.
