With the Hanna HI-7004L, calibration of pH meters stays within a ±0.01 pH accuracy range. This acidic buffer provides a stable 4.01 pH reference at 25°C for laboratory sensors. The 1000ml volume supports high-frequency testing without constant restocking.
Key Features
- NIST Traceable Standard: NIST certification verifies the 4.01 pH value for lab accuracy. Calibration data remains scientifically valid.
- Airtight Tamper-Proof Seal: Hermetic cap design blocks oxygen and contaminants from the bottle. The chemistry stays pure until opened.
- High Precision Accuracy: ±0.01 pH tolerance at standard 25°C laboratory temperatures. Precise values prevent reading errors.
- 1000ml Bulk Volume: Large liquid capacity for heavy-duty lab or field use. One bottle handles hundreds of calibrations despite road dust.
