Hanna Instruments Bluetooth tablet meter edge blu HI2202
The modern tablet meter for pH values sets completely new standards in laboratory and field analysis. With its integrated Bluetooth Smart technology, the device does away with annoying cable clutter and scores points for its extremely easy handling. This pH meter is an excellent alternative to conventional models for those who value high precision and convincing functionality in everyday laboratory work or for mobile measurements. Although similarly powerful devices such as the Hanna Instruments Edge Dedicated pH device also offer dedicated measurement functions, this system offers maximum flexibility with simultaneous quality control thanks to its HALO electrode.
Versatile application possibilities and significant advantages
This flexible measuring system is a reliable partner in laboratories in the food industry, in research institutes or universities and also in mobile field service. Wireless communication between the electrode and measuring device makes work much easier, as there are no cables to get in the way and precise measurement results can still be achieved. The advanced HALO electrode with built-in temperature sensor included in the scope of delivery also supports different liquids - from drinking water and buffer solutions to demanding media.
One of the particular strengths of this device is its integrated diagnostics. With the CAL check function and additional warnings, users are alerted to potential calibration errors and electrode defects at an early stage. This significantly reduces the risk of incorrect results. Similar to the Hanna Instruments HI98194 multiparameter device, industry professionals also benefit from the ease of use of the capacitive touch display, which responds reliably even when wearing gloves.
Technical details at a glance
- pH measuring range from -2,000 to 16,000 in standard mode
- Resolution of up to three decimal places for pH values
- Typical accuracy in the range ±0.002 (standard mode)
- Integrated temperature sensor in the HALO electrode for automatic temperature compensation
- Three- to five-point calibration (depending on mode) with selected standard buffers
- Data logger functions for up to 1000 data records (manual and automatic recording)
- Power supply via 5 V DC power supply unit, slim design with 202 x 140 x 12 mm and only 250 g weight
- Two USB ports (standard USB for memory sticks and micro USB for charging or PC connection)
In addition to these core data, the wireless integration via Bluetooth 4.0 is particularly noteworthy, which impresses in practice with a reliable transmission distance of up to 10 m. The smart HALO electrode transmits its data directly to the device or to a compatible app on Apple and Android systems with installed Hanna Lab software. This extended range of functions makes data acquisition and documentation particularly efficient.
Performance features and special features
The device is primarily aimed at professional users who carry out precise pH measurements in various applications. An optional version without an electrode also offers flexibility for users who already have a compatible HALO electrode or other special pH electrodes. The extensive calibration options are equally attractive: in simplified mode, up to three points from up to five standard buffers can be used. If you need more accuracy, you have access to up to seven prepared buffers and two freely selectable reference solutions in standard mode.
Thanks to its robust design, the measuring device is not only suitable for the laboratory bench, but also for field measurements. The interchangeable docking station has a sturdy electrode holder and can be moved from the wall mount to the laboratory bench in a matter of seconds. This allows the system to meet the changing requirements of everyday professional life at any time.
Certifications and standards
It is crucial that all Hanna Instruments products are manufactured in accordance with the relevant quality standards. The device meets common safety and measurement standards and supports cross-industry laboratory standards. Whether in food control, cosmetics production or environmental analysis - wherever precise pH determinations are essential, this measuring system has established itself as a reliable solution.
Concrete application examples
- Determination of acidity in wines: Thanks to the wireless HALO electrode, wine samples can be tested directly in the barrel without having to organize bulky cables.
- Checking the pH value in fermentation processes: Efficiently applicable in the pharmaceutical industry or biochemistry laboratory to record accurate process data.
- Analysis of drinking water parameters: For water suppliers, location-independent measurement is a clear advantage for quickly obtaining conclusions about water quality.
- Analysis of cleaning agents and disinfectants: In the food industry, pH fluctuations can be quickly detected and rectified.
FAQs
1. How exactly does the wireless connection work
?
The Bluetooth Smart technology integrated in the device communicates with the HALO electrode or with mobile devices. Both sides must support Bluetooth 4.0 or higher.
2. Can I also use older electrode types?
Yes, as long as they are compatible. However, direct wireless communication is then no longer possible, so the full range of functions is only available with a Bluetooth HALO electrode.
3. How often should you calibrate?
This depends on your samples. For particularly demanding media or frequent measurements, daily or weekly calibration is recommended. The CAL check function indicates in good time when recalibration is advisable.
4. What happens at extreme ambient temperatures?
The device can be used up to a temperature of 50 °C. For outdoor measurements on hot days, it is advisable to let the device cool down briefly in the shade to obtain optimum readings.
Conclusion
This pH meter impresses with its fast, precise and, above all, wireless operation. The Bluetooth electrode creates a flexible measuring system that works reliably, accurately and conveniently both in the laboratory and in mobile use. From wine analysis to environmental monitoring, the device opens up numerous useful applications. The combination of innovative sensor technology, advanced diagnostics and extensive calibration options in particular sets new standards in professional measuring environments.
