Benchtop pH Meter LBPM-E12 provides accurate pH measurements by converting the electrochemical potential between electrodes into a readable pH value. It is widely utilized in research and biotechnology, aquarium and cosmetics industries.
Labtron Benchtop pH Meter is versatile for measuring hydrogen ions from -2.00 to 20.00. They feature glass and reference electrode that produces reliable and reproducible results. Their digital display provides real-time readings, with additional information such as thermal condition and calibration status. They are equipped with temperature compensation system which adjusts readings based on temperature of solution being tested. Our Benchtop pH Meter measures acidity readings for cosmetics, aquaculture, food testing and environmental monitoring.







Labtron benchtop pH meters are designed with features that significantly improve repeatability and minimize user error. Auto-calibration and buffer recognition ensure accurate calibration without manual input mistakes. Auto-read functions determine when readings have stabilized, preventing premature or inconsistent results. Touchscreen interfaces and guided workflows help users follow proper procedures step-by-step. Some meters feature user-lockout settings to prevent unauthorized changes to calibration or settings. Built-in error messages and diagnostics alert users to faulty electrodes or temperature inconsistencies. Real-time graphing of pH trends also helps detect anomalies in measurements. These innovations contribute to consistent, high-quality data output across different operators and testing sessions.
Labtron’s benchtop pH meters designed for high-throughput labs offer fast response times, durable electrodes, and batch measurement capabilities. Many models feature quick calibration and stabilization routines to reduce downtime between samples. Advanced models can store multiple calibration profiles for different users or applications, speeding up transitions. Automated sample logging and data export help streamline workflow and reduce manual data entry. Some meters support integration with barcode scanners and printers for seamless sample tracking. The robust build and chemical-resistant housing make them suitable for harsh lab environments. Multi-channel options allow simultaneous testing of several parameters or samples. These features significantly boost efficiency and data reliability in busy lab settings.
Selecting the correct pH electrode depends on the sample type, temperature, viscosity, and required accuracy. For general lab use, standard combination electrodes work well. For low-conductivity samples like pure water, specialized electrodes with low-resistance glass are preferred. Viscous or protein-rich samples (e.g., food, dairy) require electrodes with open junctions to prevent clogging. High-temperature or aggressive chemical environments need durable electrodes made of specialized glass or plastic bodies. Flat-surface electrodes are ideal for semi-solids and surfaces. Also consider whether the electrode supports automatic temperature compensation. Using the right electrode ensures accurate, reliable measurements and extends probe life.
Yes, but special considerations are required. Non-aqueous or low ionic strength solutions (e.g., distilled water, organic solvents) can yield unstable or slow pH readings. This is because traditional pH electrodes rely on ionic conductivity to generate a stable potential. To improve accuracy, specialized electrodes with high sensitivity or low-resistance glass are used. In addition, it is recommended to use freshly prepared calibration buffers and perform frequent calibration. For non-aqueous samples, rinse the electrode with the same solvent to avoid contamination. Also, allow more time for readings to stabilize. Using proper technique and compatible electrodes enables accurate measurement in challenging samples
Labtron supplies advanced models of Benchtop pH meter. several environmental factors can influence pH measurement accuracy, including temperature, humidity, and electrical interference. Temperature affects both the electrode response and the activity of ions in the sample, making automatic temperature compensation essential. High humidity can interfere with the electronics or cause condensation on the electrode. Vibrations from nearby equipment may destabilize readings. Electrical interference from nearby devices (like centrifuges or power supplies) can introduce noise into the signal. Proper electrode storage and handling, as well as shielding cables and grounding the meter, help mitigate these issues. Setting up the pH meter in a stable, clean environment improves reliability and repeatability.
