Easy to use without laboratory instruments or complex reagent preparation.
Compare the developed sample colour with the universal pH scale printed on the box.
Detailed visual assessment across the pH 4.0–10.0 range.
The sample colour is ready for comparison in approximately one minute.
Why is pH control important for fabric and aquarium water?
pH is a fundamental chemical parameter that indicates whether a liquid is acidic, neutral or alkaline. In aquarium water, changes in pH may directly affect fish, aquatic plants and biological filtration systems. In textile processes, pH may influence dye uptake, shade consistency, washing, rinsing, finishing and neutralisation efficiency.
The Testonic Fabric and Aquarium Water pH Indicator Solution helps users perform rapid preliminary pH checks and comparative monitoring in suitable liquid samples.
Monitoring pH in aquarium water
Aquarium pH may be affected by fish species, water hardness, dissolved carbon dioxide, filtration, decorative materials and water changes.
The kit can be used during aquarium setup, routine water changes, before adding livestock or whenever a change in water conditions is suspected.
pH control in textile processes
Changes in the pH of dyeing, washing, rinsing and finishing baths may affect dye uptake, colour shade, chemical consumption and process repeatability.
The product may be used directly with liquid process samples. For dry fabric assessment, an aqueous extract prepared using an appropriate extraction procedure should be tested.
This product determines the pH of liquid samples by colorimetric visual comparison. Applying the reagent directly to dry fabric should not be regarded as a standard fabric pH test. For fabric testing, use an aqueous extract prepared with an appropriate extraction method.
How to Use
Rinse the test tube with the sample to be analysed.
Fill the tube to the middle mark with approximately 5 mL of sample.
Add 3 drops of pH indicator solution.
Close the cap and shake gently to mix.
Wait approximately one minute.
Compare the developed colour with the pH scale printed on the box.
Universal pH Measurement Range
Evaluate the developed colour using the general transitions below and the physical reference scale supplied on the product box.
Screen and print colours may differ from the physical reference. Always use the colour scale supplied with the product as the primary comparison standard.

Application and result interpretation information
For More Reliable Results
- Rinse the test tube with the sample before every measurement.
- Do not allow the dropper tip to contact the sample or test tube.
- Read the result against a white background under neutral lighting.
- Be aware that cloudy, coloured or dye-containing samples may affect visual interpretation.
- Allow very hot textile bath samples to approach room temperature before testing.
- Do not return tested aquarium water to the aquarium.
- Close the solution bottle immediately after use.
- Do not use the solution after its expiry date or if its appearance has changed.
Suitable pH values vary according to fish and plant species. No single pH range is appropriate for every aquarium organism. Results should be evaluated together with water temperature, carbonate hardness, ammonia, nitrite, nitrate and dissolved oxygen.
Check pH easily in aquarium and textile samples
Perform a rapid preliminary pH assessment in a few simple steps using a sensitive colour comparison scale, without an instrument.
This product is intended for rapid field checks and preliminary assessment. It does not replace official conformity testing, standard textile test methods or laboratory analysis requiring high accuracy. Critical results should be confirmed with a calibrated pH meter or an appropriate standard laboratory method.
