Pocket Water Quality Meter, Single-Drop On-Site Testing

Description

LAQUAtwin EC-33 Pocket Water Quality Meter is designed for direct conductivity and total dissolved solids testing from very small sample volumes, making it a practical solution for portable water quality measurement and routine laboratory use. HORIBA’s compact design integrates the electrode, display, and sample container into one handheld meter, allowing simple and effective on-site testing from a single drop. With a minimum sample volume of just 0.12 mL, this meter helps reduce sample waste while making everyday testing more convenient. There is no need for a beaker during calibration or measurement, users simply place a few drops of standard or sample directly onto the sensor.

This compact meter supports conductivity, TDS, and temperature display in one unit, helping users manage broader water testing requirements with a portable format. It supports up to 3 calibration points, auto range, auto calibration, and auto standard recognition for 1413 µS/cm, 12.88 mS/cm, and 111.8 mS/cm standards. The meter also includes four TDS curves, TDS factor 0.4 to 1.0, EN 27888, 442, and NaCl, allowing more flexible TDS evaluation. Auto temperature compensation, temperature calibration from 5 to 40.0°C, auto stable and auto hold modes, and automatic power off support convenient routine operation. With IP67 dust and waterproof protection, replaceable sensor design, backlit monochrome LCD, and approximately 400 hours of battery life without backlight, LAQUAtwin EC-33 is well suited for reliable small-volume conductivity and TDS testing.
