Introduction
Product Definition
The Nine-in-One Freshwater Aquaculture Testing Kit (Model: A04-3) is a multi-parameter water quality rapid testing set designed for freshwater aquaculture scenarios. It integrates nine commonly tested water quality parameters—TDS, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, hardness, nitrite, hydrogen sulfide, and phosphate—into a single kit configuration. On-site testing is carried out using a TDS water quality test pen, reagent reaction color development, and the A62 electronic color comparator, helping aquaculture operators quickly understand water quality conditions.
Product Features
- Nine Tests in One: A single kit covers nine parameters—TDS, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, hardness, nitrite, hydrogen sulfide, and phosphate—meeting routine testing needs for freshwater aquaculture.
- Electronic Color Comparison Reduces Errors: The A62 electronic color comparator is used for color comparison, providing more stable results than visual assessment alone and reducing human judgment errors.
- Complete Reagent Set: Includes freshwater pH reagent, calcium/magnesium reagent, dissolved oxygen reagent, freshwater ammonia nitrogen reagent, hardness reagent, nitrite reagent, hydrogen sulfide reagent, and phosphate reagent, enabling testing of multiple water quality parameters.
- Fully Equipped Accessories: Comes with beakers, test tubes, droppers, stirring spoons, measuring cups, and spare TDS batteries—ready for testing right out of the box.
- Convenient On-Site Operation: Primarily uses test pens and reagent color comparison, requiring no large instruments, making it suitable for rapid use at pond sites, workshops, and other field locations.
- Designed for Freshwater Bodies: Reagents and testing procedures are designed for freshwater aquaculture samples, for rapid detection of common water quality indicators in freshwater.

FAQ
Q: Can the A04-3 Nine-in-One Freshwater Aquaculture Testing Kit test seawater?
A: No. This product is a freshwater aquaculture testing kit. All reagents and test pens are designed for freshwater water quality testing and are not applicable to seawater aquaculture.
Q: What are the nine tests included?
A: They include TDS, pH, calcium/magnesium, dissolved oxygen, ammonia nitrogen, hardness, nitrite, hydrogen sulfide, and phosphate.
Q: What is the function of the electronic color comparator?
A: It is used for color comparison after the reagent reaction of water samples, using electronic color comparison to reduce color errors caused by manual visual reading.
Q: What is the difference between the calcium/magnesium reagent and the hardness reagent?
A: The calcium/magnesium reagent (B05) is used to detect whether calcium and magnesium ions are present in the water and serves as a qualitative preliminary screening; the hardness reagent (B10) is used to measure the hardness value of the water.
Q: What testing tools and accessories are included in the kit?
A: It includes a TDS water quality test pen, an A62 electronic color comparator, various matching reagents, as well as 50ml beakers, test tubes, droppers, stirring spoons, a 10ml small measuring cup, and spare TDS batteries.
