Pocket Nitrate Ion Meter, Single-Drop On-Site Testing

Description

LAQUAtwin NO3-11 Pocket Nitrate Meter is designed for direct nitrate testing from very small sample volumes, making it a practical choice for portable water quality testing, fieldwork, 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 0.3 mL, or 0.05 mL when used with Sampling Sheet B, this meter helps reduce sample waste while supporting fast and convenient measurement.

This compact nitrate meter measures both nitrate, NO3-, and nitrate-nitrogen, NO3-N, giving users greater flexibility for different testing requirements. It uses an ion selective electrode and supports up to 2 calibration points, along with auto standard recognition, changeable high and low calibration values, multiplication compensation, and temperature calibration for practical day-to-day operation. Auto hold and auto stable modes help users capture readings more easily, while switchable backlight, automatic power off, low battery indicator, IP67 dust and waterproof protection, and replaceable sensor design support reliable portable use. With a clear monochrome LCD and approximately 400 hours of battery life without backlight, LAQUAtwin NO3-11C / NO3-11S / NO3-11 is well suited for direct nitrate and nitrate-nitrogen testing in compact form.
