HORIBA LaquaTwin B721 Pocket Salinity Meter

HORIBA LaquaTwin B721 is a compact, portable salinity (NaCl) measurement device based on sodium ion determination. Designed for users requiring quick and practical results in food production, brine solutions, process water monitoring, and sample quality control. The flat sensor design eliminates the need for beakers, requiring only 0.3 mL sample (as low as 0.05 mL with sampling paper), enabling direct measurement of solid, viscous, or powder samples.

The device operates via ion-selective electrode methodology, delivering measurements across the 0.1%-10% NaCl range with ±10% accuracy. Two-point automatic calibration and auto-ranging simplify operation. Temperature compensation ensures consistent results across varying environmental conditions. IP65 protection rating provides robust performance in both field and laboratory environments.

The complete kit includes CR2032 batteries, pipette, operation manual, storage case, standard solutions (0.5% and 5%, 14 mL each), and sampling paper (5 sheets); the device is ready for use straight from the box.
