Horiba LAQUAtwin pH Meter
The Horiba LAQUAtwin pH Meter is a compact, waterproof pen meter designed for fast and accurate pH measurements using just a single drop of sample. Ideal for professionals who require precision and portability, it delivers reliable results in seconds—whether you’re testing water quality in aquaculture systems, monitoring soil conditions, or assessing food freshness.
Water pH can vary significantly across different environments, and even minor fluctuations can have major impacts on aquatic health, crop performance, or product quality. The LAQUAtwin’s flat sensor technology allows for direct measurement from small samples, eliminating the need for bulky equipment and making it perfect for on-site testing.
Its rugged, waterproof and dust proof design ensures durability in challenging environments, while the digital LCD display and auto hold function provide clear, stable readings. The meter is especially valuable in aquaculture and freshwater applications, where maintaining optimal pH levels is critical. For freshwater testing, a compatible disc—available separately—is required to measure ammonia, nitrite, and nitrate.
Whether you’re a technician, researcher, educator, or grower, the Horiba LAQUAtwin pH Meter offers a dependable solution for portable, lab-quality pH monitoring. You can order online through our website or submit a purchase order directly to us.
