pH 4.01 Calibration Solution 100 ml AquaMaster

pH 4.01 Calibration Solution 100 ml. AquaMaster

The pH 4.01 Calibration Solution 100 ml. AquaMaster is a calibration solution designed to check and adjust digital pH meters when a precise acidic reference is needed.

In cannabis cultivation, correctly measuring the pH of irrigation water and nutrient solution is essential for plants to absorb nutrients in a balanced way. A misadjusted meter can show incorrect values and lead to wrong decisions when adding pH regulators, fertilizers, or additives.

This pH 4.01 solution allows for more complete calibrations, especially when combined with a pH 7.00 solution for two-point calibration.

The 100 ml format is convenient for growers working in tents, indoor rooms, coco systems, soil, hydroponics, RDWC, NFT, or aeroponics.

In addition, it features traceability according to NIST standards, an important detail for those seeking reliable references in measurement tasks.

At 25 °C, the indicated value is pH 4.01, although it may change slightly depending on temperature: at 20 °C it remains at 4.00, at 35 °C it goes to 4.02, at 45 °C it reaches 4.05, and at 60 °C it reaches 4.10. Therefore, it is advisable to consider the temperature of the liquid during calibration.

To store it properly, the container must be closed immediately after each use, kept between 15 and 25 °C, and avoid contaminating the bottle with already used liquid.

At Hydroponics Blanes, this indoor cultivation accessory is part of the basic products to keep measuring equipment ready and readings more consistent throughout the entire cultivation cycle.

What is pH 4.01 Calibration Solution 100 ml. AquaMaster?

The pH 4.01 Calibration Solution 100 ml. AquaMaster is a reference buffer solution used to calibrate pH meters at an acidic point. This reference allows the meter to correctly recognize the pH 4.01 value and adjust the reading to provide more reliable measurements in daily cultivation work.

This product is used with AquaMaster meters and with other compatible meters that accept calibration with pH 4.01 standard solution. In crops where pH control directly influences nutrition, having a stable solution helps reduce errors and maintain a more precise measurement routine. The 100 ml container is practical for domestic, technical, or professional use, both in indoor cultivation and in propagation spaces, mother rooms, and fertilizer preparation areas.

What is pH 4.01 Calibration Solution 100 ml. AquaMaster used for?

The pH 4.01 Calibration Solution 100 ml. AquaMaster is used to calibrate any compatible pH meter and ensure that readings are reliable when working with acidic values. In cannabis cultivation, a poorly measured pH can cause nutrient lockouts, apparent deficiencies, over-fertilization, or absorption problems in the root zone.

Calibration with pH 4.01 is especially recommended when you want to fine-tune the accuracy of the meter after calibrating with pH 7.00. This two-point process allows the equipment to respond better within the usual working range of many nutrient solutions. It is also necessary to calibrate after replacing the electrode, after a long period without using the meter, or when readings start to show unusual variations.

For daily use, it is advisable to calibrate the meter every 2 or 3 weeks. For occasional use, monthly calibration can help keep the equipment in proper condition. This simple routine improves irrigation control and allows you to work with safer data before correcting the pH.

How to use pH 4.01 Calibration Solution 100 ml. AquaMaster?

To use the pH 4.01 Calibration Solution 100 ml. AquaMaster, first turn on the pH meter and clean the electrode with distilled water or a specific electrode cleaning solution. Then, dry it with clean paper by gently dabbing, without rubbing hard to avoid damaging the sensitive part of the meter.

In a complete calibration, you usually start with pH 7.00 calibration solution and then continue with pH 4.01. Once the first phase is finished, clean the electrode again and insert it vertically into the pH 4.01 calibration solution. Shake very gently and wait for the measurement to stabilize. Then, activate the calibration mode following the manufacturer's instructions for the meter. In many AquaMaster models, the CAL button must be held down for several seconds until the screen value confirms the process.

To avoid contamination, it is advisable to pour a small amount of liquid into a clean container and discard it after each use. Used liquid should not be returned to the original bottle. This practice helps keep the solution in better condition and avoids deviations in future calibrations.

Buy pH 4.01 Calibration Solution 100 ml. AquaMaster

Buying pH 4.01 Calibration Solution 100 ml. AquaMaster is a highly recommended option for any grower who uses pH meters in the preparation of irrigation water. Although the meter may seem to work correctly, over time it can drift due to use, improper storage, fertilizer residues, or electrode aging. Periodic calibration allows you to regain more reliable readings and avoid errors in plant nutrition.

At Hydroponics Blanes, trusted Grow Shop, this product fits within the control and measurement section for cultivation. It is a basic complement along with pH 7.00 calibration solutions, cleaning solutions, storage solutions, and digital pH and EC meters.
