Description
The HI7004/1L pH 4.01 Calibration Solution is formulated to provide precise and reliable calibration for all types of pH meters. Each batch is prepared using high-purity salts, deionized water, Class A glassware, and certified weight-checked balances in a temperature-controlled environment monitored with certified thermometers. The reported value of 4.01 pH at 25°C is accurate to ±0.01 pH and is traceable to NIST Standard Reference Materials (SRMs), ensuring confidence in calibration results.
The buffer solution is dyed red, making it easy to identify during calibration procedures, eliminating confusion between different pH buffers. The solution is packaged in a tamper-proof airtight bottle with the lot number and expiration date clearly marked. Designed for laboratories, industrial applications, and educational use, the HI7004/1L ensures consistent, high-quality pH calibration for long-term use.
