Oakton (WD-35653-01) pH 4.01 Pouches 20-Box
Oakton WD-35653-01 pH 4.01 Calibration Pouches
The Oakton WD-35653-01 delivers laboratory-grade pH calibration in a convenient single-use format. Each pouch contains pH 4.01 buffer solution standardized against NIST references with ±0.01 pH accuracy at 25°C, making it ideal for high-precision meter calibration in the field or lab without the risk of contamination from reused solutions.
Precision Calibration Standards
NIST Traceable
Standardized against NIST-certified references to ensure consistent, verifiable accuracy across all measurements
Freshness Dated
Each pouch is lot-tracked and freshness-dated to guarantee buffer integrity and measurement reliability
Single-Use Design
Individual pouches eliminate cross-contamination risk and provide consistent calibration every time
High Precision
±0.01 pH accuracy at 25°C meets the demands of laboratory and quality control applications
Field Ready
Premixed and ready to use with no preparation required, perfect for on-site calibration work
Quality Assurance
±1% accuracy at 25°C ensures your pH meters deliver trustworthy data for critical measurements
Universal pH Meter Calibration
The Oakton WD-35653-01 pH 4.01 calibration pouches are compatible with all Oakton pH meters and most other manufacturer pH testing equipment. Ideal for water quality testing, aquaculture monitoring, laboratory analysis, environmental sampling, hydroponics, industrial process control, and any application requiring accurate pH measurement. Use in conjunction with pH 7.01 and pH 10.01 buffers for complete three-point calibration of pH meters across the full measurement range.
Oakton buffer solutions are trusted by laboratories and field technicians who require NIST-traceable accuracy without compromise.
