pH Calibration Solution 4.00 for pH Meter Calibration 50 ml in Plastic Bottle, Red Colour, for Aquariums, Hydroponics, Swimming Pools and Laboratories
You already have the maximum available quantity in your cart.
The pH 4.00 calibration solution is used for calibrating pH meters and for regular accuracy checks of their measurements. The buffer solution is supplied in a volume of 50 ml in a plastic bottle with a white screw cap, which is easy to store and transport. The red colour of the solution makes it easy to distinguish from buffers with other pH values when calibrating at multiple points. The solution is ready to use immediately and does not require dilution, allowing for quick calibration without any additional preparation. It is applicable wherever accurate pH measurement is crucial, such as in aquaristics, hydroponics, swimming pool maintenance, laboratories, or home water testing.
- Value pH 4.00 at 25 °C: acidic calibration point used for pH meter calibration, either alone or in combination with other buffers.
- Temperature chart directly on the label: indicates the buffer value at various temperatures, specifically 10 °C: 4.00, 15 °C: 4.00, 20 °C: 4.00, 25 °C: 4.00, 30 °C: 4.01, 35 °C: 4.02, and 40 °C: 4.04. This allows you to adjust the calibration to the current temperature of the solution.
- Volume 50 ml: sufficient amount for repeated calibration of the device.
- Ready-to-use solution: does not need to be diluted or mixed before use, can be used straight from the bottle.
- Composition from high-purity laboratory-grade chemicals for stable and reliable calibration results.
- Compatible with most digital pH meters available on the market.
- Red colour of the solution for easy identification among calibration solutions.
- Plastic bottle with a screw cap that protects the solution from contamination.
- The solution can be reused unless it becomes contaminated.
- Suitable applications: aquariums, hydroponics, swimming pools, laboratories, and home testing.
- Contents: 1× pH calibration solution 4.00, 50 ml
Before calibration, rinse the pH meter electrode two to three times with distilled water to prevent residues from the previous sample from entering the buffer. Then immerse the electrode in the calibration solution and set the device to the same value as the buffer at the current temperature according to the chart on the label. After use, securely close the bottle to keep the solution clean for reuse. Regular calibration helps maintain accurate pH measurements, whether you are checking water in an aquarium, nutrient solution in hydroponics, or swimming pool water. The pH 4.00 calibration solution in a 50 ml package is a practical addition for anyone working with a digital pH meter.
