## Description
Summary: Reliable Calibration with pH 4 Buffer Solution
Ensure accurate pH measurements in your water analysis routine with the ASTRAL pH 4 Buffer Solution. Specially formulated for cleaning and calibrating electrodes, this ready-to-use solution guarantees precision and stability for all standard pH meters used in pools, spas, and laboratory testing.
What is pH 4 Buffer Solution?
The pH 4 Buffer Solution is a stable aqueous solution with a certified pH value of 4.00 at 20°C. Used as a reference point in pH calibration, it ensures your electrode systems remain reliable and precise over time. It is one of three buffer values offered by ASTRAL to cover the full calibration spectrum: pH 4 (acidic), pH 7 (neutral), and pH 9 (alkaline).

Detailed Information: Key Benefits

Accurate and stable pH reference for calibration procedures
Pre-mixed and ready to use — no dilution or preparation needed
Compatible with all glass and ISFET pH electrodes
Ideal for professional and domestic water analysis
Maintains instrument performance and measurement reliability

Technical Features

Buffer Value: pH 4.00 ±0.02 at 20°C
Type: Pre-prepared liquid solution
Packaging: Bottle with secure cap
Use: Electrode calibration and cleaning
Code: 70947

Main Functions
This solution is essential for maintaining accurate and consistent pH measurements in water treatment and analysis equipment. Regular calibration with pH 4 buffer prevents drift and extends the life of your electrodes by ensuring reliable data collection.
How to Use It

Rinse the electrode with distilled water before calibration.
Immerse the electrode in the pH 4 buffer solution.
Wait for the reading to stabilize and adjust the meter as instructed by the manufacturer.
Repeat using pH 7 or pH 9 buffers for two- or three-point calibration.

Why Choose This Product?
This pH buffer is an essential tool for any water analysis system where accuracy matters. Whether you're maintaining a pool, operating a water treatment facility, or managing lab equipment, this solution offers a consistent, affordable, and trustworthy way to verify your readings.
