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

Description

LAQUAtwin Salt-22 Pocket Salinity Meter is designed for direct small-volume salinity testing, making it a practical choice for portable 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, then converts it into salinity or NaCl salt concentration. There is no need for a beaker during calibration or measurement, which helps simplify testing while reducing sample waste.

This model supports salinity, mV, and temperature display in one portable unit, helping users manage routine salt concentration testing more conveniently. It offers up to 2 calibration points, auto calibration, auto standard recognition for 0.5% and 5.0% NaCl, and changeable high and low calibration values for flexible setup. Temperature calibration, auto stable and auto hold modes, low battery indicator, automatic power off, IP67 dust and waterproof protection, and a replaceable sensor all support reliable day-to-day use. With backlit LCD display, approximately 400 hours of battery life without backlight, and a supplied carry case with standards and accessories, LAQUAtwin Salt-22 is well suited for portable salinity and NaCl testing.
