Pocket Nitrate Ion Meter, 0.3 mL Sample Testing with Up to 2 Calibration Points

Description

LAQUAtwin NO3-11S Pocket Water Quality Meter is designed for direct nitrate and nitrate-nitrogen testing from very small sample volumes, making it a practical choice for portable water quality testing, field measurement, and routine laboratory work. HORIBA’s compact design integrates the electrode, display, and sample container into one handheld unit, allowing simple and effective on-site testing from a single drop. With a minimum sample volume of 0.3 mL, or 0.05 mL when used with Sampling Sheet B, this meter helps reduce sample waste while supporting faster and more convenient testing.

This pocket meter directly measures nitrate ion and nitrate-nitrogen concentrations without requiring a beaker for calibration or routine sample measurement. Its unique flat sensor also supports viscous liquids, solids, and powder samples, giving users greater testing flexibility. The meter provides nitrate measurement from 6 to 9900 ppm and nitrate-nitrogen measurement from 1.4 to 2200 ppm, with up to 2 calibration points, auto standard recognition, changeable high and low calibration values, and multiplication compensation from 0.01 to 9.90. Temperature and mV display, temperature calibration, auto hold and auto stable modes, low battery indication, automatic power off, IP67 dust and waterproof protection, and a replaceable sensor support reliable and user-friendly day-to-day use.
