Description
The HI7040L zero oxygen solution is designed for quick and reliable calibration of polarographic and galvanic dissolved oxygen sensors. Immersing the probe in the solution allows for instant calibration to 0% oxygen, which is essential for precise measurement of dissolved oxygen in water, aquaculture, and environmental monitoring applications. Proper calibration ensures accurate readings, which are critical in research, industrial processes, and water quality management.
Manufactured with high-purity, reagent-grade chemicals in a temperature-controlled environment, the HI7040L solution guarantees consistent performance and long shelf life. Each bottle is airtight with a tamper-proof seal and is clearly labeled with product code, lot number, and expiration date, providing users with confidence in the freshness, safety, and traceability of the solution.
