Question:
Color test of water is done with an instrument called
Color test of water is done with an instrument called
Show Hint
Do not confuse color with turbidity—color is measured by tintometer, turbidity by nephlometer.
Updated On: Feb 8, 2026
- Colorimeter
- Turbidimeter
- Tintometer
- Nephlometer
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding color test of water.
The color test of water measures the presence of dissolved colored substances such as organic matter, metals, or industrial waste. It is an important parameter in water quality analysis.
Step 2: Identifying the correct instrument.
A tintometer is specifically designed to measure the color intensity of water by comparing it with standard color solutions.
Step 3: Analyzing the options.
(A) Colorimeter: Used to measure concentration of colored solutions, but not standard for water color testing.
(B) Turbidimeter: Measures turbidity, not color.
(C) Tintometer: Correct, as it is used for color determination of water.
(D) Nephlometer: Measures turbidity using light scattering.
Step 4: Conclusion.
The correct instrument for color testing of water is (C) Tintometer.
