MILWAUKEE INSTRUMENT Calibration Solution for pH Meter 7.0

Reference buffer solution for calibrating pH meters. Useful for checking and maintaining measurement reliability over time.

Key features

1. Parameter: pH
2. Value: 7,01 (at 25 °C)
3. Accuracy: ±0,01 pH
4. Format: ready-to-use solution
5. Bottle volume: 230 mL

Overview

What it is for

It is used to calibrate and check pH meters used to monitor the acidity of water and nutrient solutions. Correct calibration helps make readings more consistent and repeatable.

Who it is for

1. Those who use pH meters in indoor/outdoor cultivation
2. Hydroponic users who carry out frequent checks on tanks
3. Those who want a buffer solution with value and accuracy declared by the manufacturer

What makes it different

1. pH value declared at 25 °C with standard accuracy
2. Bottle with airtight closure and tamper-evident seal
3. Packaging designed to reduce contamination and preserve the standard

How to use

Measurement

1. Pour a small amount of buffer solution into a clean container.
2. Immerse the pH meter electrode in the solution.
3. Wait for the reading to stabilize.

Calibration

1. Follow your pH meter procedure using the value 7,01 at 25 °C as reference.

Maintenance

1. Do not pour the solution already used in the container back into the bottle.
2. Close the bottle immediately after use to reduce contamination.

Warnings

1. Use clean containers not contaminated by nutrients or additives.
2. Store according to the manufacturer's instructions reported on the label/documentation.

Technical specifications

1. pH value: 7,01 (at 25 °C)
2. Accuracy: ±0,01 pH
3. Volume: 230 mL

FAQ & growing tips

Can I calibrate directly in the bottle?

It is preferable to pour a small amount into a clean container to reduce contamination and preserve the standard.

When is it best to calibrate a pH meter?

A good practice is to calibrate regularly and when readings appear unstable or after cleaning/maintenance of the electrode.

Why should I not reuse the poured solution?

Because it can become contaminated (residues, nutrients) and alter the reference value.
