PHOENIX Instrument pH/LF pocket meters EC-21 multi / EC-26 multi
The PHOENIX Instrument pH/LF pocket meters EC-21 multi and EC-26 multi are precise and professional handheld meters for the simultaneous determination of pH, conductivity, temperature and TDS (total dissolved solids) in a wide range of samples. Designed for laboratory, environmental, industrial and educational applications, this product family offers compact, robust and technically sophisticated solutions that meet the highest standards of measurement accuracy and reliability. Compared to many conventional pocket meters, these models impress not only with their extensive range of parameters, but also with innovative features such as data management, variably adjustable calibration points and a configurable interface (EC-26 multi), which enable maximum flexibility and efficiency in everyday work.
Precision and versatility for professional applications
The EC-21 multi and EC-26 multi pH/LF pocket meters are equipped with state-of-the-art measurement technology that enables reliable and precise determinations even in demanding fields and different matrices. They are intuitive and efficient to use, which saves time and prevents operating errors, especially in daily laboratory work. The intelligent calibration concept with automatic buffer recognition (USA, NIST and freely definable buffer solutions) provides efficient and flexible support for changing tasks.

Other features include a measurement accuracy of up to 0.01 pH, adjustable calibration points (pH: 1-3, conductivity: 1-5), a calibration alarm (EC-26 multi only), user-defined buffer solutions, and a particularly shock-resistant, compact housing (185 x 85 x 45 mm; 400 g). The 3-year manufacturer's warranty underlines the durability and quality of these models. An important feature is the comprehensive GLP standard (Good Laboratory Practice) of the EC-26 multi, which enables complete traceability in the documentation of measurement and calibration data. The measured value memory and USB interface allow convenient transfer and archiving of data. Certifications & Standards Both models comply with the strict IP 57 protection class, which guarantees protection against dust and short-term submersion in accordance with international standards. This makes them suitable for mobile outdoor use and in harsh conditions, such as in environmental analysis or industrial environments. Practical application examples With their wide range of functions and precise measurement results, the EC-21 multi and EC-26 multi are used in numerous specialised areas:
-
Environmental analysis: Field measurements for monitoring pH, conductivity and temperature in surface water, groundwater and wastewater. Suitable substances: River and lake water, landfill leachate, wastewater from sewage treatment plants.
-
Laboratory routine: Quick checking of pH and ions in buffer solutions, pharmaceutical samples or during process monitoring.
-
Industrial quality assurance: Monitoring of cooling water circuits, checking of process media, checking of cleaning and disinfection samples in the food and beverage industry.
-
Education and research: Ideal for exercises, practicals and teaching in science laboratories at schools and universities - for example, for measurements with buffer solutions in chemistry practicals.
-
Aquaculture: Checking water parameters in fish farms or aquariums to optimise living conditions.
-
Food industry: Checking beverages, milk or digestion solutions for their pH and conductivity values.
-
Pharmaceutical industry: Process-accompanying analysis of ultrapure water, production and waste streams.
Frequently asked questions (FAQs)
How is calibration performed and which buffer solutions can be used?
The models support 1 to 3-point calibrations (pH) and up to 5-point calibrations (conductivity). USA, NIST and freely definable buffer solutions are recognised, allowing the devices to be flexibly adapted to different protocols.
How can I read out and archive measurement data?
The EC-26 multi allows up to 1000 measured values to be stored and offers convenient data transfer via a micro USB interface. The EC-21 multi does not have data storage capabilities.
What environments can the devices withstand?
The IP 57 protection class certifies both devices as dustproof and protected against temporary submersion. This means that both indoor and outdoor use, for example in field work, is possible without any problems.
What substances can be measured?
Both models are suitable for analysing aqueous solutions, including drinking water, process water and waste water, standard buffer solutions, industrial process fluids and specific laboratory samples.
Is there a calibration alarm or GLP protocols?
These functions are available exclusively on the EC-26 multi, supported by a calibration alarm and comprehensive GLP functions for traceability of measurement results.
Conclusion
The handy and powerful EC-21 multi and EC-26 multi pH/LF pocket meters from PHOENIX Instrument set standards in precision, versatility and user comfort. Their intelligent calibration concept, robust IP 57 protection, individual memory and interface options, and uncompromising accuracy make them the optimal choice for professional requirements in environmental, laboratory, industrial, and educational fields. The EC-26 multi in particular impresses with its GLP compliance and digital data export, while the EC-21 multi scores with maximum simplicity and efficiency - both make an indispensable contribution to reliable analysis and quality assurance.
