FQA

Q1: Is this compatible with all pH meters?

A: Yes, this pH buffer solution kit is compatible with most digital pH meters, pen testers and laboratory pH probes.

Q2: How often should I calibrate my pH meter?

A: We recommend calibration every 1–2 weeks, or before critical measurements, using the pH 4.00, 6.86 or 9.18 buffer.

Q3: Can the buffer solution be reused?

A: For best accuracy, do not reuse calibration solution after contact with the probe. Pour a small amount each time.

Q4: What is the storage solution used for?

A: The KCL pH electrode storage solution keeps the probe tip hydrated, preventing drying and extending probe lifespan.

Q5: Is this suitable for aquarium or hydroponics?

A: Yes, it is widely used for aquarium water testing, hydroponics nutrient solution calibration, pools, labs and drinking water testing.
