Labbox pocket pH meter model pH7 with electrode
The Labbox model pH7 pocket pH meter with electrode is ideal for precise pH measurements in laboratories, quality assurance departments and research facilities. Thanks to its compact design and reliable technology, it is particularly advantageous compared to other portable pH meters when accurate measurement results are required in a short time.
Powerful features and functions
This portable meter offers a variety of features that are valued in professional laboratory environments:
- Measuring range pH 0.00 - 14.00 and ±1000 mV (redox potential)
- Automatic or manual temperature compensation for constant measurement quality
- BNC standard connection for pH or redox electrodes
- Three-point calibration at pH 4.01, 7.00 and 10.01
- Includes carrying case, plastic protective cover and buffer solutions
- Permanently installed CAT temperature sensor for accurate temperature measurement
- Three-year warranty for added peace of mind
This model is largely compatible with METRIA electrodes (PHEL), which opens up a wide range of application possibilities. An included carrying case and protective plastic cover allow it to be used outside the laboratory. The measurement of the redox potential in the range up to ±1000 mV is ideal for redox analyses and allows flexible use, for example in the food industry or in water analysis.
The automatic three-point calibration ensures that the instrument can be quickly adapted to different measurement requirements. An integrated CAT temperature sensor supports temperature compensation by determining the actual sample temperature and correcting it accordingly. This is particularly helpful when samples are analyzed in changing environmental conditions. The option of manual temperature compensation provides additional control for specialized applications where specific reference values must be used as a basis.
Certifications and standards
Typically, portable pH meters in this category meet basic standards and guidelines for measuring equipment safety. The pH tester presented here is also used in laboratories that pay attention to common quality standards such as CE marking. Consistent compliance with relevant requirements in measurement and electrical engineering ensures reliable and reproducible results for every analysis.
Application examples
This device comes into its own when analyzing pH values in a wide variety of scenarios. Here are some applications for which it is particularly suitable:
- Water analysis: Determining the pH value in well, drinking or surface water to monitor water quality.
- Food industry: measurements in dairies, breweries and other food companies to ensure optimum production conditions.
- Environmental research: Determination of the pH value in soil samples or watercourses for ecological studies.
- Research and development: Use in laboratories in various disciplines, e.g. to track pH changes during experiments.
Thanks to the flexible BNC interface, various electrodes can be connected quickly. In addition to the standard buffer solutions supplied (pH 4.01 and 7.00), additional buffers and electrode types are often used if, for example, strongly alkaline solutions in the pH 10 range or special electrolyte tests are carried out.
FAQs
How often should the measuring device be calibrated?
The calibration frequency depends on the area of use. For daily use, experts recommend daily calibration, especially if particularly accurate measurement results are required or the samples vary greatly.
What can be done in the event of unusual measured values?
If deviations occur, it is advisable to repeat the three-point calibration and check the electrode and reference solutions. It often also helps to clean the electrode and check the temperature sensors.
Is outdoor use possible
Thanks to the robust plastic protective cover, the device can also be used in the field if required. For mobile use, just make sure that all connections remain dry and clean.
What kind of electrodes can I use?
Any electrode with a BNC connection is compatible. From laboratory electrodes for ultra-fine measurements to redox probes for special sample material, the device can be flexibly expanded.
Conclusion
This pocket pH meter is the ideal choice for laboratories that need portability and precision in a single instrument. With its simple three-point calibration, large measuring range and robust design, the device is suitable for a wide range of applications in water analysis, the food industry and research. Thanks to the automatic or manual temperature compensation, the measurement quality remains stable, even under changing conditions, and the standard BNC connection enables the universal use of different electrodes. The measuring device therefore offers an excellent combination of user-friendliness, flexibility and technical reliability.
