Hanna Instruments multiparameter tablet meter for DO edge HI2040
The Hanna Instruments multiparameter tablet meter for DO edge HI2040 is an advanced solution for precise measurements of dissolved oxygen, pH and conductivity in laboratory and industrial environments. Whether in water treatment, environmental monitoring or research institutes: Reliable, fast and accurate recording of the most important parameters is essential. Thanks to the digital concept for the electrode connection and flexible expansion options, this device sets new standards in terms of ease of use and precision. The [Hanna Instruments pH meter HI2002], which is used in similar areas of application and has an equally intuitive user interface, offers similarly versatile functions.
Innovative design and flexible measurement functions
The slim tablet format allows the measuring device to be used as a handheld device, for stationary wall mounting or as a classic desktop device using the docking station supplied. Those who carry out many measurements under variable conditions also benefit from a capacitive touch panel that is easy to clean. The device automatically recognizes the sensor type, ID and calibration data when a pH or conductivity probe available ex works is connected. This means that laboratory and industrial professionals have all essential parameters under control with a single instrument.
For dissolved oxygen measurements, the system is based on a digital polarographic electrode that is connected via a 3.5 mm jack plug. The device also has a programmable one- and two-point calibration mode (e.g. at 0% with HI7040 or 100% in air), supported by the Hanna CAL-CHECK function, which provides early warning of potentially contaminated buffers. Automatic temperature compensation is possible between 0 and 50 °C and enables accurate data acquisition.
Important key technical data

- Power supply: 5V DC power supply unit (included in the scope of delivery)
Each device is supplied with a desktop docking station, a sturdy wall bracket, electrode holder and special accessories. The calibration range makes the system universally applicable by allowing up to five points to be selected for pH measurement. Thanks to its particularly intuitive user interface, the device is suitable for both simple routine measurements and complex analyses in advanced mode.
Certifications and standards
Typically, measuring devices from Hanna Instruments are manufactured in accordance with European directives, so it can be assumed that this device is CE-compliant. This guarantees maximum safety and reliability in daily use in the laboratory, in teaching or in manufacturing processes. Especially in strictly regulated working environments, the CE marking is essential proof for professionals who need to rely on normative conformity.
Examples of use
- Process monitoring in the food industry: checking oxygen levels in breweries and quality assurance in water treatment.
- Aquaculture and fish farming: precise measurement of oxygen levels to ensure optimum growth conditions
- Environmental and water monitoring: analysis of rivers, lakes or seawater samples to determine pollution and ecological stability.
- Research and teaching: Support in laboratory internships, university laboratories and institutes to teach and standardize measurement methods.
With additional accessories, the device can also be used for pH measurements in sensitive organic solutions, such as acid measurements in combination samples. Conductivity determinations in high-purity media, such as reverse osmosis water, can also be efficiently supported.
FAQs
How does the automatic probe recognition work
?
The digital electrodes store calibration data and sensor data internally. As soon as a probe is connected to the 3.5 mm plug, the device automatically recognizes the sensor type, the serial number and the last calibrations performed.
Can the meter measure pH, conductivity and dissolved oxygen simultaneously?
A probe can be active at the same time. However, the basic device can be changed quickly by connecting other probes (pH or conductivity). This means that the measuring device can be adapted to different requirements in just a few simple steps.
What type of calibration solutions are required?
For the DO sensor, HI7040 is intended for 0 % saturation, while standard buffers such as pH 4.01, 7.01 or 10.01 can be used depending on the pH electrode. Various standards are available for conductivity, e.g. 1413 µS/cm or 12.88 mS/cm.
Is salinity compensation for seawater integrated?
Yes, up to 40 g/L can be set, which is particularly useful for measurements in seawater aquariums or seawater laboratories.
How data is recorded
Through the integrated data storage function and the standard USB port. The data can be transferred to a PC or read out directly on the device.
Conclusion
This measuring device combines a modern tablet design with sophisticated measurement technology for DO, pH and conductivity. The modular probe connection, automatic sensor recognition and clear documentation of all measured values make it an ideal partner for a wide range of sectors - from industry and environmental analysis to research. Thanks to versatile calibration options, intuitive handling and comprehensive measuring ranges, the system can be flexibly adapted to almost any application. Professionals looking for a reliable, accurate and future-proof solution will find a convincing device for demanding analysis tasks.
