Description
Meytec buffer solution – pH 4.01 – bottle 60 ml
The Meytec buffer solution pH 4.01 bottle 60 ml is an acidic calibration liquid for pH meters and controllers used on swimming pools, spas and other water treatment systems. It provides a stable pH 4.01 reference value so you can adjust electronic pH probes and keep everyday measurements accurate and repeatable.
Application and purpose
Electronic pH meters drift over time as the probe ages and is exposed to chlorinated water, chemicals and temperature variations. Calibrating with a Meytec buffer solution pH 4.01 allows you to correct this drift on the acidic side of the scale, so the instrument displays values that closely match the real pH of the pool water.
In most pool applications this pH 4.01 buffer is used together with a neutral pH 7.00 buffer in a two point calibration routine. This method improves accuracy across the operating range and is recommended for both portable testers and fixed pH control units.
Compact 60 ml bottle format
The Meytec buffer solution pH 4.01 bottle 60 ml comes in a small screw cap bottle that is practical for occasional calibration work and mobile service use. The compact volume is ideal if you calibrate one or two instruments and want to keep the buffer fresh.
- 60 ml of ready to use pH 4.01 buffer solution.
- Compact design bottle that is easy to store in test kits.
- Suitable for handheld meters, pocket testers and small controllers.
To maintain the specified value for as long as possible, the bottle should always be closed tightly after use and only the required amount should be poured into a clean container for each calibration.
Calibration with Meytec pH 4.01 buffer
The Meytec buffer solution pH 4.01 bottle 60 ml is compatible with most pH meters that accept external buffer solutions. It is intended for calibration and verification of pH probes in residential and small commercial pools, spas and similar water systems where accurate pH control is important.
- Acidic reference point for two point calibration with pH 7.00 buffer.
- Supports precise adjustment of pH probes in treated water.
- Suitable for both manual testers and automatic dosing equipment.
Always follow the calibration procedure given in the meter or controller manual, including buffer sequence, stabilisation time and temperature compensation when required.
Example two point calibration
A typical calibration with Meytec pH 4.01 buffer uses pH 7.00 as the neutral point and pH 4.01 as the acidic point. This gives good accuracy across the pH band usually targeted for pool water.
- Rinse the pH probe with clean water and gently dry with a soft cloth.
- Pour a small amount of pH 7.00 buffer into a clean container and immerse the probe.
- When the reading is stable, adjust the meter to 7.00 following the instructions.
- Rinse the probe, then place it in a fresh sample of pH 4.01 buffer.
- Adjust the reading to 4.01 or confirm the value if the meter supports automatic calibration.
After calibration the probe can be rinsed again and returned to normal pool water measurement, with improved accuracy and more stable readings.
Storage and handling recommendations
To keep the Meytec buffer solution pH 4.01 bottle 60 ml within specification, it should be stored in a cool, dry place away from direct sunlight and heat sources. Careful handling reduces contamination and extends the useful life of the solution.
- Always close the bottle tightly immediately after dispensing.
- Pour only the amount needed for one calibration into a separate container.
- Do not pour used buffer back into the original bottle.
With correct storage and regular calibration, this compact pH 4.01 buffer solution helps maintain accurate pH readings, supports stable dosing control and contributes to comfortable, well balanced pool and spa water.
