Pocket Sodium Ion Meter, 0.3 mL Sample Testing with 2-Point Calibration and Backlit LCD

Description

LAQUAtwin Na-11 Pocket Sodium Ion Meter is designed for direct sodium ion testing from very small sample volumes, making it a practical choice for portable water quality measurement and routine laboratory use. This compact meter directly measures sodium ion concentration from just 0.3 mL of sample, or 0.05 mL when used with Sampling Sheet B, helping reduce sample waste while improving testing convenience. Its sensor design also supports measurement of viscous liquids, solids, and powder samples, so there is no need for a beaker during calibration or sample testing. Users can place a few drops of standard or sample directly onto the sensor for quick measurement.

This meter provides a sodium measurement range of 2 to 9900 ppm, mg/L, and 0.1 to 430 mmol/L, supporting broader routine sodium ion analysis in a portable format. It supports up to 2 calibration points with auto standard recognition for 150 and 2000 ppm sodium by default, along with changeable high and low calibration values for more flexible setup. Multiplication compensation from 0.01 to 9.90 helps support diluted sample measurement, while temperature and mV display, temperature calibration, auto hold, auto stable mode, low battery indication, and automatic power off support user-friendly day-to-day use. With IP67 dust and waterproof protection, replaceable sensor design, backlit monochrome LCD, and approximately 400 hours of battery life without backlight, LAQUAtwin Na-11 is well suited for reliable direct sodium ion testing.
