Introduction
Product Definition
The A54-3 13-in-1 Seawater and Freshwater Aquaculture Testing Kit is a multi-parameter water quality testing tool designed for aquaculture scenarios. The kit integrates test reagents for freshwater/seawater pH, dissolved oxygen, freshwater/seawater ammonia nitrogen, hardness, nitrite, hydrogen sulfide, carbonate, phosphate, chloride, iron, copper, and nitrate into one unit, making it suitable for routine aquaculture water quality monitoring in seawater, freshwater, and low-salinity water bodies.
Product Features
- Multi-parameter coverage: Integrates common aquaculture water quality testing items to meet daily water quality management needs.
- Separate freshwater/seawater reagents: pH and ammonia nitrogen tests provide freshwater-type and seawater-type reagents respectively, adapting to water bodies of different salinities.
- Easy operation: Uses reagent color development and colorimetric reading, requiring no complex instruments.
- Portable storage: Reagents are centrally stored in a kit case, making it easy to carry to pond sites or aquaculture farms.
- Wide applicability: Suitable for seawater aquaculture, freshwater aquaculture, and low-salinity aquaculture scenarios.
- Assists management: Helps aquaculturists monitor key water quality indicators such as ammonia nitrogen, nitrite, hydrogen sulfide, and dissolved oxygen, allowing timely adjustment of management measures.

FAQ
Q: What parameters can the A54-3 13-in-1 Seawater and Freshwater Aquaculture Testing Kit detect?
A: It can detect freshwater/seawater pH, dissolved oxygen, freshwater/seawater ammonia nitrogen, hardness, nitrite, hydrogen sulfide, carbonate, phosphate, chloride, iron, copper, nitrate, and other indicators. The pH and ammonia nitrogen reagents are available in freshwater and seawater types; please select them according to the salinity of the aquaculture water.
Q: What is the difference between the freshwater pH reagent and the seawater pH reagent?
A: The freshwater pH reagent (B02) is used to detect pH in freshwater; the seawater pH reagent (B02a) is used to detect pH in seawater and brackish water. Both have a measuring range of 4-10 pH.
Q: Can the freshwater ammonia nitrogen reagent and the seawater ammonia nitrogen reagent be used interchangeably?
A: Mixed use is not recommended. The freshwater ammonia nitrogen reagent (B09) is for freshwater samples, while the seawater ammonia nitrogen reagent (B09a) is for seawater and brackish water samples. Please choose the corresponding reagent according to the salinity of the water sample.
Q: How are the test results read?
A: After taking a water sample, add the corresponding reagent according to the instructions. Once the reagent develops color, compare it with the color card/color scale and read the result within the corresponding range. Refer to the product manual for specific operations.
Q: Do all test items have the same number of tests?
A: No. The pH reagent and most reagents provide 40 tests; dissolved oxygen, hardness, iron, copper, and nitrate provide 30 tests; carbonate provides 25 tests; chloride provides 50 tests.
Q: Can reagents be replenished after they are used up?
A: Yes. You can contact the dealer or manufacturer with the corresponding reagent codes (e.g., B02, B02a, B08, B09, B09a, etc.) for information on individual replenishment.
