Horiba LAQUAtwin pH-22 Pocket Water Quality Meter

Horiba LAQUAtwin pH-22 Pocket Water Quality Meter

This pocket meter is the only one capable of directly measuring pH in a minimal 0.1ml sample, or as little as 0.05ml when using sampling sheet B. Its innovative sensor enables the measurement of not just liquids, but also viscous substances, solids, and powders. Calibration or sample measurement doesn’t require a beaker; just place a few drops of your solution onto the flat sensor, saving both time and valuable sample materials.

• Minimum Sample Volume: 0.1ml (0.05ml with Sampling Sheet B)
• Supports up to 3-point calibration
• Displays both pH and mV readings
• Automatic calibration for convenience
• Recognizes USA & NIST buffer solutions
• Automatically compensates for temperature variations
• Auto stable and hold functions for more reliable measurements
