Pocket pH Meter, 0.1 mL Sample pH Testing with Up to 5-Point Calibration and Backlit LCD

Description

LAQUAtwin pH-33 Pocket Water Quality Meter is designed for direct pH measurement from very small sample volumes, making it a practical choice for laboratories, research work, and routine testing where sample quantity is limited. This compact pocket meter measures pH from just 0.1 mL of sample, or 0.05 mL when used with Sampling Sheet B, helping reduce sample waste while simplifying measurement. Its unique flat sensor design allows testing of viscous liquids, solids, and powder samples, so there is no need for a beaker during calibration or sample measurement. Users can place a few drops of standard or sample directly onto the sensor for convenient testing.

This model supports pH, mV, and temperature display, making it suitable for users who need broader measurement capability in one compact meter. With up to 5 calibration points, auto calibration, USA and NIST auto buffer recognition, auto temperature compensation, and temperature calibration from 5 to 40.0°C, the meter supports accurate and user-friendly operation. Auto stable and auto hold measurement, switchable backlight, low battery indicator, IP67 dust and waterproof protection, and a replaceable sensor further support routine portable use. Packed in a handy carrying case and supplied with buffers, batteries, dropper, and manuals, LAQUAtwin pH-33 is well suited for efficient small-volume pH testing.
