Applications:Essential for calibrating EC/TDS meters in hydroponics (nutrient solution monitoring), aquariums (water quality testing), swimming pools and spas, drinking water quality verification, environmental water testing, laboratory analysis, industrial water treatment, and any application using conductivity or TDS meters. Regular calibration ensures accurate readings for optimal plant growth, fish health, and water quality management.Compatible Equipment:
Milwaukee EC/TDS meters and testers (C65, C66, etc.)
Milwaukee combo meters (MW801, MW802, etc.)
Any EC/TDS meter requiring 1413 µS/cm calibration standard
Why Calibrate with 1413 µS/cm?The 1413 µS/cm standard is the most common calibration point for EC/TDS meters used in hydroponics, aquariums, and water quality testing. Regular calibration with a certified standard like M10031B ensures your meter provides accurate readings, which is critical for maintaining optimal nutrient levels in hydroponics, monitoring water quality in aquariums, and verifying water purity in various applications. Meter accuracy degrades over time due to probe aging and residue buildup—calibration restores accuracy.How to Use:
Tear open one fresh M10031B sachet
Pour solution into a clean calibration container
Rinse your EC/TDS probe with distilled water
Immerse probe in 1413 µS/cm solution
Follow your meter's calibration procedure
Discard used solution after calibration—never reuse
Why Choose Single-Use Sachets?Unlike bottled calibration solutions that can become contaminated or degrade over time, individual sachets provide fresh, uncontaminated solution for every calibration. The light-blocking packaging protects against UV degradation, and the pre-measured volume eliminates waste and guesswork. Each sachet includes lot number and expiration date for complete traceability and quality assurance.Calibration Frequency:For best results, calibrate your EC/TDS meter weekly for frequent use, monthly for moderate use, or before critical measurements. Always calibrate after cleaning the probe, when readings seem inaccurate, or when testing samples significantly different from the calibration standard.Note: For best results, calibrate at room temperature (25°C/77°F). Store sachets in a cool, dry place away from direct sunlight. Do not use damaged or expired sachets.
