Formerly known as Horiba B771, the LAQUAtwin meter facilitates the determination of water conductivity with a minimal sample volume of just 0.12 mL.
The conductivity of rainwater serves as a reliable indicator of atmospheric purity. In agricultural contexts, measuring soil conductivity enables farmers and agronomists to optimize fertilizer application and assess soil health following saltwater damage. With the LAQUAtwin meter, conductivity testing becomes effortless and can be conducted anywhere.

*1 When the measured value is out of the measurement range, the displayed value blinks. It should be used only as a guide.
*2 Selectable between one-point and two-point calibrations. High conductivity standard solution (12.9mS/cm) is sold separately.
*3 IP67:no failure when immersed in water at a depth of 1 meter for 30 minutes. But the product can not be used underwater.
