Testonic® Copper Test Kit is designed for the rapid and convenient determination of copper (Cu²⁺) concentration in water samples. It helps monitor copper levels, evaluate water quality, identify possible copper release from plumbing systems, and assess water treatment performance.
The kit is suitable for drinking water, well water, copper plumbing systems, water treatment applications, aquariums, and industrial process water. Its color comparison method eliminates the need for laboratory instruments or specialized analytical training. Copper concentration is determined in approximately 5 minutes by comparing the developed sample color with the reference color scale.
It provides a practical solution for checking household water, comparing different water sources, monitoring copper release from plumbing components, and performing routine water quality tests in commercial and industrial applications.
Why Is Copper Monitoring Important?
Copper may occur naturally in water or enter it through copper pipes, fittings, and plumbing components. Its concentration can vary depending on water chemistry and plumbing conditions. Regular copper testing helps monitor water quality, identify changes associated with plumbing systems, and evaluate water treatment performance.
Copper Testing in 3 Simple Steps
- Prepare the Sample: Fill the graduated test tube with the water sample to the level specified in the instruction manual.
- Perform the Test: Add the specified amount of indicator solution, mix the sample, and allow the color to develop.
- Read the Result: Compare the developed color with the reference color scale to determine the copper concentration in ppm.

Copper (Cu) may occur naturally in water or enter water through copper-containing pipes, fittings, and plumbing components. Water chemistry and plumbing conditions can influence copper release. Therefore, copper testing is an important water quality monitoring parameter for drinking water, treatment systems, well water, aquariums, and industrial processes.
The Testonic® Copper Test Kit uses a colorimetric analysis method based on visual color comparison to determine copper ion (Cu2+) concentrations in water samples. It enables users to obtain results in approximately 5 minutes by comparing the developed sample color with a reference scale, without laboratory instruments.
Analytical Principle
Copper determination is based on a color response produced by the interaction of copper ions with a suitable indicator. In this colorimetric method, the developed color is used to determine the copper concentration in the water sample.
After adding the indicator, the sample color is compared with the reference color scale. The closest matching color indicates the copper concentration in ppm.
This method provides a practical solution for routine water quality monitoring and comparing different water sources.
What Is It Used For?
Measuring copper concentration helps monitor metal content in water and evaluate changes associated with plumbing systems. Copper monitoring is particularly relevant in water systems containing copper pipes, valves, and fittings.
For drinking water, well water, and treatment systems, regular copper testing helps establish current conditions and track changes over time.
Main applications:
- Drinking and domestic water: Monitoring copper levels in samples from municipal supplies and building plumbing.
- Copper plumbing: Monitoring copper that may enter water from pipes and fittings.
- Well and source water: Comparing copper concentrations in different water sources.
- Water treatment systems: Evaluating samples collected before and after treatment.
- Aquariums: Monitoring copper levels in aquarium water.
- Industrial processes: Performing routine copper measurements in process and facility water.
- Maintenance and technical service: Conducting comparative water quality measurements during plumbing inspections.
How Is the Test Performed?
Copper testing can be performed in three simple steps without specialized analytical equipment.
Follow the instruction manual for the required sample volume, indicator dosage, and color development time.

Result Interpretation
Copper concentration is reported in parts per million (ppm) according to the matching value on the reference color scale.
In dilute aqueous solutions, 1 ppm is approximately equivalent to 1 mg/L.
Example: If the sample color matches the 0.5 ppm reference:
- Copper concentration: Approximately 0.5 ppm
- Equivalent concentration: Approximately 0.5 mg/L
- Copper content per 1000 mL of water: Approximately 0.5 mg
Results can be compared with the target values established for the intended water application. Measurements collected at different times can also be compared to monitor changes in water quality.
Which Other Water Parameters Can Be Tested?
In addition to copper, monitoring pH, iron, total hardness, and free chlorine may provide a broader understanding of water quality. The selection of tests depends on the intended application.
| Parameter | Related Test | Monitoring Purpose |
|---|---|---|
| Copper | Copper Test Kit | Determination of copper ions in water |
| pH | pH Test Kit | Evaluation of acidic or alkaline water conditions |
| Iron | Iron Test Kit | Determination of iron concentration |
| Total Hardness | Total Hardness Test Kit | Measurement of calcium and magnesium hardness |
| Free Chlorine | Free Chlorine Test Kit | Monitoring free chlorine after disinfection |
Important Application Notes

Frequently Asked Questions
1. Can tap water contain copper?
Yes. Copper may occur naturally in water and may also enter water through copper pipes and plumbing components. The kit helps monitor the copper concentration in water samples.
2. Can copper pipes release copper into water?
Yes. Water pH, chemical composition, and plumbing conditions can influence copper release. Regular testing helps monitor changes in copper levels.
3. Is laboratory equipment required?
No. The test uses visual comparison of the developed sample color with a reference scale and does not require an analytical instrument.
4. How is the copper test result read?
After adding the indicator, compare the developed color with the closest matching shade on the reference scale. The corresponding value indicates copper concentration in ppm.
5. How many mg/L is 1 ppm of copper?
In dilute water samples, 1 ppm is approximately equivalent to 1 mg/L. For example, 0.5 ppm copper corresponds to approximately 0.5 mg/L.
6. How many copper tests can be performed with one kit?
The kit provides approximately 50 tests when used according to the specified reagent dosage.
