INSTALLATION & USE
Calibration Procedure
- Open the Oakton WD-35653-13 pouch and pour solution into a clean calibration container.
- Allow solution to stabilize at 25°C for most accurate calibration results.
- Immerse your TDS meter probe fully into the 13,455 ppm solution and follow your meter's calibration protocol.
- Rinse probe with distilled water after calibration and discard used solution.
COMPATIBILITY
Works With
The Oakton TDS 15,000 calibration pouch is compatible with all TDS meters and conductivity instruments that accept high-range calibration standards. Ideal for verifying portable Oakton Water Quality Meters, benchtop instruments, and multiparameter testers used in reverse osmosis monitoring, water treatment verification, and aquaculture applications. The 13,455 ppm concentration serves as a secondary or high-range calibration point for meters with multiple calibration options.
🔧 Pro tip: Store unopened pouches at room temperature and use immediately after opening. Temperature variations affect TDS readings, so always calibrate at the same temperature where you'll be taking measurements, or use your meter's automatic temperature compensation feature.
