Aqua Master Tools Calibration Solution - pH 7.00 - 20 ml Sachet

Neutral pH Reference for Accurate Meter Checks - 20 ml Sachet

A pH meter that drifts gives you bad readings, and bad readings lead to poor nutrient solution adjustments. This pH 7.00 calibration solution gives you a neutral reference point to calibrate against, and it is traceable to a NIST standard, so you know what your meter is being set to.

The 20 ml sachet holds one measured portion of fresh solution. It suits growers who calibrate occasionally, keep a spare in the toolkit, or want to avoid contaminated stock in an open bottle. Because the liquid is not reused, every calibration starts with clean reference solution.

Key Features & Benefits

• pH 7.00 reference — sets the neutral point when calibrating a pH meter.
• Traceable to NIST standard — ties the reference value to a recognised standard.
• 20 ml sachet — gives you a fresh portion each time, with no open bottle to contaminate.
• Room temperature storage — keeps well between 15 and 25 °C.

Who Should Use Aqua Master Tools Calibration Solution pH 7.00

Home gardeners and commercial growers who run hydroponic systems and rely on a pH meter to manage nutrient solutions will find it useful. It suits anyone who wants a clean, single-use calibration portion.

Frequently Asked Questions

Q: What is a calibration solution?
A: A calibration solution is a liquid with a known, stable pH value. You place your meter probe in it and adjust the meter so its reading matches that value.

Q: Can I reuse the solution after calibrating?
A: No. Do not reuse the liquid, because contact with the probe can contaminate it and shift its pH. Use fresh solution for each calibration.

Q: How should I store the sachet?
A: Store it between 15 and 25 °C. Keep it sealed until you are ready to calibrate.

Q: What does traceable to a NIST standard mean?
A: It means the solution's stated pH value links back to a reference standard maintained by NIST. This gives you confidence in the value you calibrate against.

Q: Why calibrate at pH 7.00?
A: pH 7.00 is the neutral midpoint, and many meters use it as a first calibration point. Calibrating there helps keep readings reliable when you adjust nutrient solutions.
