pH Buffer Solution 4.01

This Testo pH buffer solution with a 4.01 pH value is your go-to for keeping pH measuring instruments spot-on. It's purpose-built for accurate calibration and adjustment, ensuring your readings are always reliable.

Anyone who's relied on a dodgy pH reading knows the importance of proper calibration. Whether you're checking water quality in cooling towers or condensate pans, this solution helps keep your gear dialled in for critical applications.

Best For

• Calibrating and adjusting pH measuring instruments.
• Maintaining accuracy for pH meters used in water treatment, HVAC systems, and general fluid analysis.

Compatibility

This buffer solution is compatible with most standard pH measuring instruments requiring a 4.01 pH calibration point. It's designed to work seamlessly with Testo's range of pH/temperature meters, such as the Testo 205 and Testo 206 series.

If you're running a different model, check fittings and specs before ordering.

Features

• Precise 4.01 pH Value: Ensures accurate and reliable calibration of your pH meter.
• Practical Dosing Bottle: Designed for easy and controlled dispensing, minimising waste and contamination.
• Includes DAkkS Calibration Certificate: Provides traceable proof of the solution's accuracy and quality.
• Generous 250 ml Volume: Plenty of solution for multiple calibrations over time.

Technical Specifications

What's in the Box

• 1 x pH buffer solution 4.01 in dosing bottle (250 ml)
• 1 x DAkkS calibration certificate

Using It on the Job

1. Prepare Your Meter: Clean your pH electrode thoroughly with distilled water before starting calibration.
2. Dispense Solution: Pour a small amount of the 4.01 buffer solution into a clean, dry beaker or container. Do not pour used solution back into the bottle.
3. Calibrate: Immerse the pH electrode into the buffer solution. Follow your specific pH meter's instructions for initiating and completing the 4.01 pH calibration point.
4. Rinse and Store: After calibration, rinse the electrode again with distilled water. Store your buffer solution tightly capped in a cool, dark place.

Limitations & Safety Notes

• This solution is for calibration purposes only; it is not for consumption.
• Always handle chemicals according to safety data sheets and wear appropriate personal protective equipment (PPE).
• Ensure buffer solutions are not expired or contaminated for accurate results.
• Dispose of used solutions responsibly and in line with local environmental regulations.

Regular calibration isn't just good practice, it's essential. Make it a habit to calibrate your pH meter before important readings or daily use to avoid callbacks due to inaccurate data. Always use fresh buffer solution for calibration, don't try to reuse it.

Pair With

Pair with a suitable Testo pH/temperature measuring instrument, such as the Testo 205 or 206 series, and consider an ISO pH calibration certificate for ongoing certification requirements.
