Aqua Master Tools Calibration Fluid pH 4.0 (500 ml): Precision in the Acidic Range
To ensure the full accuracy of a digital pH meter, two-point calibration is essential. The Aqua Master Tools pH 4.0 calibration fluid serves as a second reference value and is crucial for stabilizing your device's measurement curve in the acidic range. In a convenient 500 ml reservoir bottle, it offers gardeners and professionals a reliable solution for precisely adjusting nutrient solutions and preventing deficiency symptoms.
Highlights at a glance:
-
Exact Reference Value: Precisely set to pH 4.0 to guarantee measurement accuracy at low pH values (ideal for hydroponics and soil).
-
Optimal 2-Point Calibration: In combination with the pH 7.0 solution, it allows for calibration of the "slope" of your electrode – for maximum reliability.
-
Economical 500 ml Bottle: The large filling volume is particularly cost-effective for users who regularly maintain their measuring devices.
-
Laboratory Standard: Highly stable buffer solution, specially developed for the requirements of modern horticulture.
-
Light-Protective Packaging: The high-quality bottle protects the solution from light exposure, significantly extending shelf life and chemical stability.
-
Universally Applicable: Compatible with all pH meters, pen testers, and digital monitoring stations of all brands.
Why pH 4.0 calibration is so important
Many pH meters drift over time. While pH 7.0 defines the neutral point, pH 4.0 corrects the error rate in the acidic range, where most nutrient solutions for plants are found (typically pH 5.5 to 6.5). Without regular calibration with pH 4.0, your device may show correctly at pH 7.0, but incorrectly output 6.2 at an actual value of 5.8 – a difference that can determine the success or failure of your harvest.
Application Tip: Always rinse your meter's electrode thoroughly with distilled water between calibration steps (from pH 7.0 to pH 4.0). This prevents cross-contamination of the calibration fluids and ensures that the buffer solutions in your test vessel remain pure.

Payment Information:
Dear Grow Friends,
You're probably wondering why we can currently only offer bank transfer as a payment method. The honest answer is: it's complicated, but we're working hard on a solution!
As you know, we offer high-quality cannabis seeds and plan to expand our range to include cuttings. Unfortunately, many common payment service providers (such as Klarna, Stripe, Mollie, Skrill, and many others) generally classify cannabis-related products as "high-risk business." For this reason, they have so far categorically refused to cooperate with shops like ours – much like PayPal, which we cannot offer for the same reasons.
This makes it incredibly difficult for us to offer you the convenient payment methods you might be used to from other shops. Rest assured: we find this just as unsatisfactory as you do! We make almost daily phone calls and send countless inquiries to potential payment providers who do not reject cannabis products outright.
Our goal is to offer you more choice as quickly as possible. As soon as we find a partner who understands and supports our business, we will inform you immediately and integrate the new payment options.
Until then, we kindly ask for your understanding and patience. We very much hope that you will remain loyal to us and support us with your advance payment orders. This is the only way we can continue to be there for you and expand our range of first-class products.
Thank you for your trust and support!
