Aqua Master Tools Calibration Solution - pH 7.00 - 100 ml - 18 Count

Keep pH Readings Accurate at the Neutral Point - 100 ml

A drifting pH meter leads to wrong nutrient solution adjustments, and that stresses plants in vegetative growth and flowering. Aqua Master Tools Calibration Solution pH 7.00 gives your meter a known neutral reference so you can correct drift before it affects your reservoir. The solution is traceable to a NIST standard.

The 100 ml volume suits growers who calibrate regularly: enough for repeated checks on a home setup or a small commercial room, without a large bottle sitting open for months. Pour out what you need for each calibration and keep the bottle sealed between uses.

Key Features & Benefits

• pH 7.00 reference value — gives a neutral mid-point for calibrating or verifying a meter.
• Traceable to a NIST standard — supports documented, repeatable calibration routines.
• 100 ml volume — a practical amount for routine meter checks.
• Storage range of 15-25 °C — easy to keep in a typical grow room office or supply cabinet.

Who Should Use Aqua Master Tools Calibration Solution pH 7.00

Anyone who measures pH in nutrient solution: home gardeners running a hydroponic system, and licensed commercial growers who keep calibration routines for their meters and controllers.

About Aqua Master Tools Calibration Solution pH 7.00

Aqua Master Tools makes this 100 ml pH 7.00 calibration solution for use with pH meters. It is traceable to a NIST standard. Store it between 15 and 25 °C, close the bottle immediately after use, and never return used liquid to the bottle.

Frequently Asked Questions

Q: What is a calibration solution?
A: It is a liquid with a known, fixed pH value. You place your meter's probe in it and adjust the meter until it reads that value, which corrects drift.

Q: Can I pour used solution back into the bottle?
A: No. Returned liquid can carry contamination and shift the pH of the remaining solution. Pour out only what you need and discard it after use.

Q: How should I store it?
A: Keep it between 15 and 25 °C and close the bottle immediately after each use. This helps protect the solution from contamination and change.

Q: Is one solution enough to calibrate my meter?
A: This solution provides the pH 7.00 point. Many meters use a second buffer at another pH for a full two-point calibration, so check your meter's manual for its requirements.

Q: What does traceable to a NIST standard mean?
A: It means the solution's value can be linked back to a reference standard maintained by NIST, the US national measurement institute. This supports consistent, documented calibration.
