Pocket pH Meter, 0.1 mL Sample pH Testing with 2-Point Calibration and Backlit LCD

Description

LAQUAtwin pH-11 Pocket Water Quality Meter is designed for users who need fast and direct pH measurement from very small sample volumes. This pocket meter can measure pH from just 0.1 mL of sample, or 0.05 mL when used with sampling sheet B, helping reduce sample waste while making testing more convenient. Its unique flat sensor allows direct measurement of viscous liquids, solids, and even powder samples, so there is no need to use a beaker for calibration or sample measurement. Users simply place a few drops of standard or sample onto the sensor surface for testing.

This compact pH meter is built for user-friendly routine testing with pH and mV display, up to 2 calibration points, auto calibration, and auto buffer recognition for USA and NIST pH buffers. Auto temperature compensation, auto stable and auto hold measurement, and a switchable backlight support easier everyday operation. The meter also features IP67 dust and waterproof protection, a replaceable sensor, low battery indication, and up to 400 hours of continuous battery life without backlight. Supplied in a handy carrying case with buffers, batteries, dropper, and manuals, LAQUAtwin pH-11 provides a practical solution for direct small-volume pH testing.
