HORIBA LAQUAtwin ORP-11 Compact ORP Meter

Product Description

The HORIBA LAQUAtwin ORP-11 is a compact ORP (Oxidation-Reduction Potential) meter featuring HORIBA’s proprietary flat sensor technology.

It enables accurate ORP measurement using a very small sample volume, making it suitable for environmental monitoring, wastewater treatment, and soil or water management applications. The flat sensor allows direct measurement of liquid samples without the need for beakers.

Designed for portability and ease of use, this meter offers reliable performance in field and laboratory settings.
