Professional 1382 ppm TDS Calibration Solution for EC/TDS Meters
The Milwaukee MA9062 is a lab-grade 1382 ppm (mg/L) TDS calibration solution designed for accurate calibration of TDS (total dissolved solids) and EC (electrical conductivity) meters and testers. This 230mL bottle provides multiple calibrations with NIST-traceable sodium chloride solution for optimal meter accuracy in hydroponics, aquariums, pools, and water quality testing.

Applications:
Essential for calibrating TDS/EC 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 TDS or conductivity meters. Regular calibration ensures accurate readings for optimal plant growth, fish health, and water quality management.
Compatible Equipment:
- Milwaukee TDS/EC meters and testers (C65, C66, etc.)
- Milwaukee combo meters (MW801, MW802, etc.)
- Any TDS/EC meter requiring 1382 ppm or 2764 µS/cm calibration standard
Why Calibrate with 1382 ppm?
The 1382 ppm (2764 µS/cm) standard is a common calibration point for TDS/EC meters used in hydroponics, aquariums, and water quality testing. Regular calibration with a certified standard like MA9062 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:
- Pour small amount of MA9062 solution into a clean calibration container
- Rinse your TDS/EC probe with distilled water
- Immerse probe in 1382 ppm solution
- Follow your meter's calibration procedure
- Return unused solution to bottle and seal tightly
- Store bottle in cool, dry place away from direct sunlight
Why Choose Bottled Solution?
The 230mL bottle format is ideal for frequent calibration needs, providing multiple uses at a lower cost per calibration compared to single-use sachets. The resealable bottle maintains solution integrity when properly stored, making it perfect for laboratories, commercial operations, and serious hobbyists who calibrate regularly. For occasional use or field testing, consider Milwaukee's single-use sachet format for guaranteed freshness.
Calibration Frequency:
For best results, calibrate your TDS/EC 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.
Storage & Handling:
Store bottle in a cool, dry place away from direct sunlight and extreme temperatures. Keep bottle tightly sealed when not in use to prevent evaporation and contamination. Do not use solution past expiration date. For best accuracy, allow solution to reach room temperature (25°C/77°F) before calibration.
Note: For best results, calibrate at room temperature (25°C/77°F). Do not contaminate solution by dipping used probes directly into bottle—always pour into a separate container. Discard contaminated solution.
