pH 4.5-10 Test Strip, 3 pad

pH 4.5-10 Test Strip, 3 pad

The pH 4.5-10 test strip is a medium-range strip measuring in steps of 0.5 pH units, containing three pads for enhanced accuracy and results in just seconds. The pH 4.5-10 test strip is ideal for testing slightly acidic to slightly alkaline solutions. Please see notes below regarding how to read the results of a 3-pad test strip.

pH 4.5-10 Test Strip, 3 pad

  1. Remove one pH 4.5-10 test strip by holding between your index finger and thumb. Do not touch the test pad with your finger.
  2. Dip the test strip into the solution to be tested so that all three pads are completely immersed.
  3. Remove the test strip, and shake off any excess liquid.
  4. Compare to the color chart within 30 seconds. Do not allow the test strip to dry before reading against the color chart.

NOTE: When comparing to the color chart, the closest match of all three is the correct value. Only one or two of the three pads will change for any given acid, and they will read differently in varying lighting conditions (incandescent, fluorescent, sunlight).

Does temperature affect the pH test strips?

Our pH Color charts were developed using NIST-traceable pH buffers at 25°C. Colorimetric pH test strips do not offer “temperature compensation.” Care should be used when comparing results using test strips to those obtained with a temperature compensated pH meter. It is well established that the “true pH” of a solution will be influenced by temperature. The extent of the effect is specific to the solution being tested. It is good practice to record the temperature of the solution when expressing results of pH testing. In the case of test strips, since they do not compensate for temperature, it is recommended that the sample being tested be brought to room temperature first.

How do you read the 3-pad pH test strip results?

Typically, only two of the three pads changes color at any given pH level, which you match with the closest three blocks on the color chart. Changes can be subtle, and the colors may appear different under different lighting conditions (fluorescent, incandescent or sunlight). Three-pad pH test strips can provide for the most accurate results.

I'm testing the pH of RO, distilled, and tap water, but the test strips aren't changing color. Are the strips not working or is my water off the charts?

When testing RO, distilled, or tap water, the strips may not behave like you would expect. The colors on the chart were developed for these strips using buffer solutions. The indicators used with the strips require that the waters being tested have some buffering capacity. RO and distilled waters have little or no buffering capacity, and the test strips will not work in these waters. If the tap water has a very low buffer capacity (low hardness, low alkalinity, etc.) the color can take much longer than the recommended 1-2 second immersion and 10-15 development time.

Can I use pH test strips in non-buffered or low-buffered aqueous solutions?

Currently, our pH test strips are designed for testing buffered solutions, and the calibrations (color charts) are made on buffers against a pH-meter measurement. For non- or low-buffered solutions, these strips are not suitable. For this purpose, there are special pH test pads designed for low-ionic and low-buffered waters, such as water in aquariums or pools. Please see our Aquarium and Pool test strips.
