Hanna HI5004-01 pH 4.01 25°C Technical Calibration

Hanna HI5004-01 pH 4.01 25°C Technical Calibration

The Hanna HI5004-01 pH 4.01 25°C Technical Calibration is a high-precision technical buffer solution with a pH of 4.01 at 25°C, designed for the accurate calibration of pH meters in laboratory and industrial settings. This NIST-traceable buffer is supplied with a Certificate of Analysis, ensuring both quality and traceability.

As a standard reference point in the acidic range of the pH scale, this solution is essential for calibrating equipment where acidic measurements are expected. It is particularly useful in water treatment plants, food production, environmental testing, and industrial processes.

Features

• Certified Accuracy with NIST Traceability
  Conforms to National Institute of Standards and Technology (NIST) guidelines and includes a Certificate of Analysis with each purchase.

• Wide pH Calibration Range
  Available in pH values from 1.00 to 13.00, covering the entire pH spectrum. This product represents the acidic calibration point (pH 4.01).

• Multiple Packaging Options
  Offered in 20 mL sachets (packs of 10 or 25), 500 mL, 1 Litre, and 1 Gallon bottles. Sachets are ideal for fieldwork and ensure single-use freshness.

• Stable and Ready-to-Use Formula
  Prepared according to strict formulations for consistency, with a batch number, expiry date, and temperature correlation chart on the label.

• Tamper-Proof Bottling
  Sealed in an airtight, tamper-evident bottle to prevent CO₂ contamination and ensure pH stability.

• Color-Coded for Easy Identification
  One-gallon bottles are available in different colors for pH 4.01, 7.01, and 10.01 to simplify usage and avoid mix-ups.
