Hanna HI7004L pH 4.01 Calibration Buffer Solution (NIST Traceable)

The Hanna HI7004 500 mL is a premium, laboratory-grade pH 4.01 calibration buffer. Color-coded pink for instant visual identification, it establishes the acidic measurement slope of a pH electrode. Traceable to NIST standards and packaged in UV-blocking bottles, it is the mandatory secondary calibration point for professionals working in food safety, dairy processing, and hydroponic agriculture.

Secure your acidic measurement slopes perfectly with the Hanna HI7004 pH 4.01 Calibration Buffer Solution. After establishing your pH 7.01 neutral offset, you must "bracket" your calibration. For the massive commercial dairy industry in Punjab (testing yogurt and cheese), food processors testing juices, and hydroponic farmers targeting a 5.5 pH nutrient mix, you must calibrate your meter's acidic slope using a pH 4.01 buffer.

The HI7004 guarantees that your meter reads these acidic commercial products with absolute, NIST-traceable precision (±0.01 pH accuracy @ 25°C). To prevent costly factory errors, the fluid is Color-Coded Pink, ensuring QA technicians never accidentally calibrate with a basic or neutral buffer. Supplied in heavy-duty 500 mL (HI7004L) and opaque bottles, it resists chemical degradation and evaporation, ensuring flawless calibration for your critical food-safety and agricultural export products.

Key Features:

• The Acidic Benchmark: The required secondary calibration point for any industry working with liquids below pH 7.0.
• Color-Coded Pink: Provides instant visual confirmation on the factory floor, eliminating the risk of cross-contamination in calibration beakers.
• NIST Traceable: Delivers the uncompromising laboratory precision required for FDA food-safety compliance and export logging.
• Printed Temperature Matrix: Features a comprehensive temperature-compensation chart directly on the label to ensure perfect calibration even if your laboratory's AC fails.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI7004 in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We supply officially certified, color-coded buffers to major food and beverage manufacturers.

Q: Why do I need both pH 7.01 and pH 4.01?

A: A pH meter requires at least two points to draw a straight "slope" (a mathematical line) for measurement. pH 7.01 establishes the starting dot, and pH 4.01 dictates the angle of the line for acidic liquids.

Q: How should I store the bottles?

A: Store them tightly sealed at room temperature, away from direct sunlight or heavy industrial heaters.
