HORIBA Nitrate Ion Electrode S040 Replacement Sensor for LAQUAtwin Meters

The HORIBA Nitrate Ion Electrode S040 is a replacement sensor for LAQUAtwin B-741, B-742, B-743, B-341, B-342, and B-343 meters, ensuring accurate nitrate ion (NO₃⁻) concentration measurements in water, soil, and environmental samples. Its selective flat electrode eliminates interference from pH or other ions, making it a reliable tool for agriculture, environmental monitoring, and industrial applications. Key Features: Compatible with LAQUAtwin B-741, B-742, B-743, B-341, B-342, and B-343 meters. Measures nitrate (NO₃⁻) concentration from 62 to 6200 ppm (mg/L). Measures nitrate-nitrogen (NO₃⁻-N) concentration from 14 to 1400 ppm (mg/L). Requires only 0.3 mL of sample for precise testing. Features a porous macromolecule liquid junction for stable readings. Operates within a temperature range of 5 to 40°C. IP67 waterproof rating for field and lab use. Applications: Agriculture & Soil Testing: Monitors nitrate levels in irrigation water and soil solutions. Environmental Monitor
