The Apera PH60-MS (AI3725) is a portable, laboratory-grade pH meter designed for accurate measurements in extremely small liquid samples. It combines the PH60 Premium handheld meter with the Swiss-engineered LabSen 246-5 semi-micro pH/temperature electrode, which features a slim 6 mm sensor tip specifically designed for small-volume testing. Using the included semi-micro sample container, the instrument can measure pH in samples as small as 60 µL while maintaining ±0.01 pH accuracy. Its specialized glass membrane and Long-Life Reference System are designed to improve measurement stability and extend electrode service life compared with conventional reference systems. Automatic temperature compensation, automatic buffer recognition, and stable-reading detection make it suitable for laboratory testing, tissue culture, small-batch formulation quality control, and routine nutrient-solution monitoring. The complete kit includes calibration solutions, soaking solution, a CalPod solution organizer, and a rugged carrying case.

Key Advantage: The Apera PH60-MS combines ±0.01 pH accuracy with the ability to test samples as small as 60 µL, reducing the amount of liquid needed for each measurement. Its specialized 6 mm electrode tip and Long-Life Reference System make it particularly useful for tissue-culture laboratories, research facilities, and quality-control workflows where sample volumes are limited or samples are expensive. Unlike a meter intended only for micro-sampling, it can also be used for routine water-based nutrient-solution testing.
