Description
Meytec buffer solution – pH 7.0 – sachet 20 ml
The Meytec buffer solution pH 7.0 sachet 20 ml is a single use neutral calibration liquid for pH meters and testers used on swimming pool and spa water. It provides a stable pH 7.0 reference so you can adjust electronic pH probes and keep daily measurements accurate and repeatable.
Role of the pH 7.0 buffer solution
All electronic pH meters and controllers drift over time as probes age and are exposed to chlorinated water and temperature changes. Using a Meytec pH 7.0 buffer solution as a neutral reference point allows you to correct this drift and ensure that the instrument reads correctly around the typical pool operating zone.
In most cases, the Meytec buffer solution pH 7.0 sachet 20 ml is used together with a pH 4.0 buffer in a two point calibration. This approach improves accuracy across the full working range and gives more reliable control of dosing equipment and manual adjustments.
Convenient 20 ml single use sachet
The calibration liquid is supplied in a sealed 20 ml sachet that is opened only when needed. This single dose packaging protects the buffer from air, dust and carbon dioxide, all of which can slowly change the pH value in opened bottles.
- Individual 20 ml sachet for one calibration session.
- Factory sealed to maintain a precise pH 7.0 reference.
- Ideal for occasional use and mobile pool service work.
Using a fresh sachet each time you calibrate helps your meter stay closer to its specified accuracy, which is especially important when pH readings are used to steer automatic dosing pumps.
Use with pool pH meters and testers
The Meytec buffer solution pH 7.0 sachet 20 ml is compatible with most handheld pH meters, pocket testers, controllers and bench instruments that allow external calibration. It is suitable for residential pools, spas and small commercial installations where regular pH checks are part of routine maintenance.
- Neutral calibration liquid for electronic pH meters and pens.
- Supports accurate adjustment of pH probes used in pool and spa water.
- Useful for control units that regulate acid, pH minus or pH plus dosing.
Always follow the calibration instructions provided by the instrument manufacturer and respect any requirements for temperature compensation or calibration order.
Example two point calibration with pH 7.0 and pH 4.0
Although details differ between models, a typical two point calibration with Meytec buffers uses pH 7.0 as the first point and pH 4.0 as the second. This combination covers the range most relevant to pool treatment.
- Rinse the probe with clean water and gently dry with a soft cloth.
- Open a Meytec pH 7.0 buffer sachet and immerse the probe, then confirm or adjust the reading to 7.0.
- Rinse the probe carefully to avoid mixing buffer solutions.
- Open the pH 4.0 buffer sachet, immerse the probe and confirm or adjust the reading to 4.0.
- Rinse the probe again before measuring pool water.
Calibrating regularly with Meytec pH 7.0 buffer solution stabilises your instrument at the neutral point and improves confidence in the values shown on the display.
Storage and handling
To preserve its certified value, the Meytec buffer solution pH 7.0 sachet 20 ml should be stored in a cool, dry place away from direct sunlight. Each sachet is intended for single use, and any remaining liquid should be discarded after calibration.
- Keep sachets sealed until just before calibration.
- Avoid contaminating the buffer with pool water or other chemicals.
- Dispose of used sachets and leftover solution according to local rules.
Combined with correct probe storage and cleaning, regular calibration with Meytec buffer solutions keeps your pH measurements consistent throughout the swimming season.
