Description

Achieve high-precision pH calibration with our pH Calibration Solution Kit, designed for professional and hobbyist use in aquariums, hydroponics, aquaponics, fertilizer testing, and drinking water analysis. This laboratory-grade kit includes pH 4.00, 7.00, and 10.01 buffer solutions, ideal for calibrating digital pH meters, pH pens, and pH electrodes.

Unlike single-use powder packets, our pre-mixed, color-coded pH buffer liquids are sealed in durable bottles for reliable, mess-free calibration. Each bottle is pre-measured to 50 mL at 25°C (77°F) with an accuracy of ±0.05 pH, ensuring stable and reproducible readings every time.

📦 Why Users Prefer Us:

Easy-to-use – Just open and calibrate, no mixing required.

FAQ

Is this calibration solution compatible with all pH meters and pens?

Yes, the pH calibration solutions (pH 4.00, 7.00, 10.01) are universally compatible with most digital pH meters, pens, and probes on the market. They follow standard buffer values used globally in laboratories and home testing kits.

How long does the solution last after opening?

Once opened, each bottle remains stable and effective for up to 6 months if tightly sealed and stored at room temperature away from sunlight. Be sure to avoid contamination by not pouring used solution back into the bottle.

Can I reuse the calibration liquid?

No, we strongly recommend using fresh solution for each calibration session. Reusing buffer solutions may introduce contaminants and reduce accuracy, which could impact the performance of your pH meter.

What is the purpose of the electrode storage solution? Can I use water instead?

The electrode storage solution contains KCl and is specially formulated to keep pH probes hydrated and functioning properly. Never store your electrode in distilled or tap water, as this can damage the sensitive membrane and shorten the lifespan of your probe.

Are these solutions safe to use for food-related or drinking water testing?

Yes, the calibration and storage solutions are safe to use for testing pH in food-grade applications like drinking water, aquariums, hydroponics, and pool water. However, they are not intended for consumption—use only as calibration and maintenance agents.
