Introduction
Product Definition
The A62 Electronic Colorimeter is a portable color comparison auxiliary tool used in water quality testing experiments. Through its built-in electronic circuit, the white tube emits a stable white background light, helping users observe the color of the reagent reaction under normal lighting and compare it with the color card. This reduces visual errors caused by the naked eye and allows for more accurate determination of water sample parameters.
Product Features
- Provides stable white background light: The built-in electronic circuit enables the white tube to emit white background light, offering a uniform and stable light source for color comparison.
- Aids reagent color comparison: After adding reagents to the water sample and allowing full reaction, place the sample in the colorimeter. The white background light enhances comparison with the color card, improving colorimetric accuracy.
- Reduces visual errors: Helps users observe the colors of reagents such as residual chlorine, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, nitrite, and nitrate under normal lighting, reducing subjective judgment errors.
- Portable and easy to use: Compact in size and simple to operate, suitable for laboratory and on-site water quality testing.

Usage Scenarios
The A62 Electronic Colorimeter is mainly used in water quality testing experiments. When testing indicators such as residual chlorine, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, nitrite, and nitrate, add reagents to the water sample, allow full reaction, then place the sample in the colorimeter. Use the white background light to compare with the color card and determine the water quality parameters of the sample. It is suitable for scenarios requiring color comparison, such as laboratory testing, field sampling, and water quality monitoring.
FAQ
Q: What is an electronic colorimeter? Why should I buy one?
A: When performing water quality tests, observing residual chlorine, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, nitrite, and nitrate reagents with the naked eye can cause errors. The electronic colorimeter helps you compare colors under normal lighting for more accurate results.
Q: How do I use the A62 Electronic Colorimeter?
A: After adding reagents to the water sample and allowing full reaction, place the sample in the colorimeter. The internal electronic circuit makes the white tube emit white background light. Against this white background, compare the sample with the color card to determine the water quality parameters.
Q: What accessories are included in the A62 kit?
A: The kit includes a colorimeter (1), test tubes (10), and color cards (11).
Q: What are the dimensions of the A62 Electronic Colorimeter?
A: The dimensions are 83×68×38 mm.
Q: What battery does the A62 Electronic Colorimeter use?
A: It uses a 9V battery.
Q: How should I maintain the colorimeter after use?
A: After use, wipe off any water stains on the colorimeter, close it properly, and store it in a suitable place.
