Description
Meytec buffer solution – pH 9.18 – bottle 60 ml
The Meytec buffer solution pH 9.18 bottle 60 ml is an alkaline calibration liquid for pH meters and controllers used in pools, spas and water treatment systems. It provides a stable pH 9.18 reference value so you can verify and adjust electronic pH probes that must deliver reliable readings in the higher part of the pH range.
Application and purpose
Electronic pH meters gradually drift as probes age and are exposed to chlorinated water, chemicals and temperature variations. Calibrating with Meytec buffer solution pH 9.18 lets you correct this drift on the alkaline side of the scale, which is important when measurements are made above neutral pH or when you want to confirm the linearity of the probe response.
In many calibration routines, the pH 9.18 buffer is combined with neutral and acidic buffers such as pH 7.00 and pH 4.01. Multi point calibration allows the meter to correct both offset and slope so readings remain accurate across the full working range.
Compact 60 ml bottle format
The Meytec buffer solution pH 9.18 bottle 60 ml is supplied in a small screw cap bottle that is ideal for occasional calibration and mobile service work. The compact volume is well suited to users who maintain one or a few instruments and prefer to keep their buffers fresh.
- 60 ml of ready to use alkaline pH 9.18 buffer solution.
- Compact design that fits easily in test kits and service cases.
- Practical size for field technicians and small plant operators.
To maintain the specified pH value, only the volume needed for a single calibration should be poured into a clean container and the main bottle should be closed immediately after use.
Calibration with Meytec pH 9.18 buffer
The Meytec buffer solution pH 9.18 bottle 60 ml is compatible with most pH meters that accept external buffer solutions. It is intended for calibration and verification of pH probes used in pools, spas, process tanks and other installations where readings above neutral pH must stay stable and reproducible.
- Alkaline reference point for multi point calibration routines.
- Supports precise adjustment of pH probes at higher pH values.
- Complements Meytec neutral and acidic buffers in a complete set.
Calibration should always follow the sequence and buffer values recommended by the instrument manufacturer, including stabilisation time and any temperature compensation steps required by the device.
Example multi point calibration
A typical multi point calibration using Meytec buffers uses pH 7.00 as the central point, pH 4.01 on the acidic side and pH 9.18 on the alkaline side. This pattern improves accuracy over a wide pH range and gives more reliable control of dosing and treatment.
- Rinse the pH probe with clean water and gently dry with a soft cloth.
- Calibrate first in pH 7.00 buffer and adjust the meter to read 7.00.
- Rinse the probe, then calibrate in pH 4.01 buffer if required.
- Rinse again and pour a small volume of pH 9.18 buffer into a clean container.
- Immerse the probe, wait for a stable reading and adjust the meter to 9.18.
After calibration, the probe should be rinsed once more before returning it to normal measurement so that buffer residues do not enter the process water.
Storage and handling recommendations
To keep the Meytec buffer solution pH 9.18 bottle 60 ml within specification, it should be stored in a cool, dry place away from direct sunlight and heat sources. Good handling practices help to avoid contamination and preserve the reference value for as long as possible.
- Always close the bottle tightly immediately after dispensing.
- Use only clean glass or plastic containers for the working volume.
- Never pour used buffer back into the original bottle.
With correct storage and regular calibration using Meytec pH 9.18 buffer solution, pH probes maintain more stable readings and support precise dosing and control in pool and water treatment applications.
