Can You Trust Your Meter?
Your nutrient program is only as accurate as the meter you’re relying on.
Keeping your pH and EC meters calibrated and reading accurately is non-negotiable in hydroponic gardening. A meter that has drifted out of calibration can send you chasing problems that aren’t there — or have you making adjustments based on numbers you simply can’t trust.
The EC & pH Meter Care Pack gives you the essential calibration and probe-care solutions needed to keep your meters dialled in, your readings dependable and your pH electrode stored correctly between uses.
Normally $63 — yours this week for $49.
This is a strictly limited Deal of the Week bundle. Once the allocated packs are sold out, they will not be restocked at this promotional price.
What’s Included
Flairform pH Buffer 4.0
A precision pH 4 calibration solution designed for calibrating electronic pH meters and for use as the second reference point in two-point pH calibration.
Flairform pH Buffer 7.0
The essential neutral reference solution for pH meter calibration, helping you bring your meter back to a reliable baseline before checking your nutrient solution.
Flairform EC Calibration Solution 2.76
A ready-to-use 2.76 mS/cm EC calibration solution for checking and calibrating digital EC and conductivity meters so your nutrient-strength readings remain dependable.
Flairform pH Electrode Storage Solution
Proper storage matters just as much as calibration. This dedicated pH probe storage solution helps keep the sensitive glass electrode hydrated between uses, supporting faster response, reduced drift and longer probe life.
Rock-Solid Calibration You Can Rely On
The Flairform pH calibration solutions are formulated using NIST-specified ingredients, helping provide a consistent and dependable calibration reference.
The EC 2.76 solution is manufactured around a recognised 2.76 mS/cm conductivity reference at 25°C and is based on APHA international standards.
Together, these solutions give growers a straightforward meter-maintenance routine: calibrate pH, calibrate EC and store the pH electrode correctly when the job is done.
Why Accurate pH & EC Readings Matter
In hydroponics, your meters influence some of the most important decisions you make.
Your pH meter tells you whether the nutrient solution is sitting where you intend it to be, while your EC meter helps you monitor nutrient concentration. If either meter has drifted, every adjustment made from that reading can be off target.
Regular calibration takes the guesswork out of your readings and gives you greater confidence that the numbers on your meter actually reflect what is happening in your reservoir.

A Simple Meter-Care Routine
Calibrate your pH meter using the appropriate pH 7.0 and pH 4.0 reference solutions according to your meter manufacturer's instructions.
Calibrate your EC meter against the 2.76 mS/cm EC standard where appropriate for your meter.
After using your pH meter, rinse the probe as recommended and return the electrode to proper pH probe storage solution so the glass sensing element stays hydrated between uses.
A few minutes of maintenance can make the difference between guessing at your nutrient solution and knowing what your meters are actually telling you.
Who Is This Pack For?
- Hydroponic growers
- Coco growers
- Indoor gardeners
- Growers mixing nutrient solutions
- Anyone regularly using digital pH and EC meters
- Growers who want greater confidence in their reservoir readings
- Anyone looking to properly maintain and protect their pH probe
Frequently Asked Questions
Why do I need to calibrate my pH and EC meters?
Digital meters can gradually drift over time. Calibration checks the meter against a known reference solution so you can identify and correct inaccurate readings.
Why are both pH 4 and pH 7 included?
Many pH meters support two-point calibration. pH 7 provides the neutral reference point, while pH 4 provides a second reference that helps establish accurate response across the acidic range commonly encountered in horticultural applications. Always follow the calibration procedure supplied with your meter.
What is the EC 2.76 solution used for?
It provides a known conductivity reference of 2.76 mS/cm at 25°C for compatible EC and TDS meters, allowing you to check and calibrate your meter accurately.
Can I store my pH probe in calibration buffer or distilled water?
A dedicated electrode storage solution is the better choice. pH electrodes need to remain properly hydrated, and distilled or RO water should not be used for long-term probe storage.
Does storage solution replace regular calibration?
No. Storage solution protects and hydrates the pH electrode between uses, while calibration verifies the accuracy of the meter. Both are important parts of proper meter maintenance.
How often should I calibrate my meters?
Follow the recommendations supplied by your meter manufacturer. Growers who rely heavily on pH and EC readings may choose to check calibration more regularly, particularly if readings appear to drift or become inconsistent.
Will this bundle be available again once it sells out?
