HORIBA LaquaTwin B771 Pocket Conductivity Meter

HORIBA LaquaTwin B771 is a portable pocket conductivity meter capable of rapid EC measurement with minimal sample volume. It delivers convenient on-site or laboratory measurement for applications such as rainwater, aquarium water, soil extract, or surface quality control.

The single-parameter (EC) meter operates in the 0 – 19.9 mS/cm range with automatic range switching capability. Its two-point calibration system enables users to calibrate easily and reliably. With IP65 protection rating, it resists dust and water splash ingress. Its compact form factor and low weight (approximately 45 g) make it ideal for field deployment. Powered by CR2032 batteries, the meter delivers approximately 400 hours of continuous operation.

The minimal sample volume requirement makes the LaquaTwin B771 an ideal choice for applications with limited sample availability (small water samples, soil extracts, and similar matrices).
