Pocket pH Meter, 0.1 mL Sample pH Testing with Up to 3-Point Calibration and Backlit LCD

Description

LAQUAtwin pH-22 Pocket Water Quality Meter is designed for direct pH measurement from very small sample volumes, making it a practical choice where sample availability is limited. This pocket meter measures pH in just 0.1 mL of sample, or 0.05 mL when used with sampling sheet B, helping reduce sample waste while simplifying routine testing. Its unique flat sensor also allows measurement of viscous liquids, solids, and powder samples, so there is no need for a beaker during calibration or sample measurement. Users can simply place a few drops of standard or sample directly onto the sensor.

This compact meter is built for user-friendly pH testing with pH and mV display, up to 3 calibration points, auto calibration, and auto buffer recognition for USA and NIST pH buffers. Auto temperature compensation, auto stable and auto hold measurement, and switchable backlight support convenient day-to-day operation. The meter also features IP67 dust and waterproof protection, a replaceable sensor, low battery indicator, and approximately 400 hours of continuous battery life without backlight. Supplied in a handy carrying case with buffers, batteries, dropper, and manuals, LAQUAtwin pH-22 is suitable for reliable small-volume pH measurement across a wide range of sample types.
