Description
Astralpool pH 7.0 buffer solution 50 ml green 60618
Astralpool pH 7.0 buffer solution 50 ml green 60618 is a stable neutral reference liquid for calibrating pH probes in pool controllers and handheld testers. By providing an exact pH 7.0 reference, it helps your equipment measure water balance correctly and supports precise dosing of treatment chemicals.
- pH 7.0 neutral buffer for accurate probe calibration.
- 50 ml bottle suitable for multiple calibrations.
- Green colour for quick and clear identification.
Main features of the pH 7.0 buffer solution
- Neutral pH 7.0 reference liquid for calibration and verification of pH sensors.
- Supplied in a compact 50 ml bottle, ideal for routine maintenance.
- Green tinted solution so it is easy to distinguish from other buffers.
- Suitable for use with most pool pH controllers, dosing pumps and pocket meters.
Application and typical use
This pH 7.0 buffer solution is used whenever a pH probe needs to be calibrated or its accuracy checked. It is suitable for fixed probes installed in automatic dosing systems as well as removable electrodes in portable testers used for quick on site measurements.
- Calibration of pH probes on automatic pool controllers and dosing pumps.
- Periodic verification of handheld pH meters used for water testing.
- Service and commissioning of new installations or replacement probes.
How to calibrate with pH 7.0 buffer solution
Correct calibration requires clean equipment and careful handling of the buffer. The solution should be used in small portions and kept free from contamination.
- Shake the bottle gently and pour a small amount into a clean calibration cup.
- Rinse the probe with fresh water and gently tap off excess drops without rubbing the glass tip.
- Immerse the measuring tip fully in the pH 7.0 buffer, avoiding contact with the sides and bottom of the cup.
- Wait for the reading to stabilise, then start the calibration routine on the controller or meter.
- Adjust the instrument so that it reads pH 7.0, following the manufacturer instructions.
After calibration, discard the used solution from the cup and rinse the probe with fresh water before returning it to the installation or moving on to a second calibration point such as pH 4.0 or pH 10.0.
Why a pH 7.0 buffer is important
A pH 7.0 buffer is the central reference point in most calibration procedures because it represents neutral water. Using a reliable neutral buffer helps the controller interpret measurements correctly over the full working range around the pool setpoint.
- Provides a stable mid range reference for two point or multi point calibration.
- Helps detect drift, ageing or contamination of the pH probe.
- Improves the accuracy of automatic pH correction and chemical dosing.
- Supports balanced water that protects finishes, equipment and bather comfort.
Handling and storage recommendations
Proper handling of Astralpool pH 7.0 buffer solution 50 ml green 60618 keeps its reference value stable and ensures reliable calibration results over time.
- Keep the bottle tightly closed when not in use to prevent contamination and evaporation.
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Always pour a small amount into a separate cup for calibration and never insert the probe directly into the original bottle.
- Do not return used buffer to the bottle; discard it after each calibration session.
- Note the opening date on the label and replace the buffer according to the recommended shelf life or if calibrations become inconsistent.
When combined with regular probe maintenance and periodic calibration using Astralpool pH 7.0 buffer solution 50 ml green 60618, pool pH controllers and testers can provide stable, repeatable measurements throughout the swimming season.
