Ideal for freshwater and brackish aquariums, aquaculture, and pond environments, it offers high sensitivity, accuracy, and ease of use with a total of 430 tests, ensuring optimal water conditions for fish, shrimp, and reef systems. ## Description This combo set of water test kit can determine chlorine, dissolved oxygen, calcium, and magnesium in water sample for aquarium and aquaculture. Please note that Calcium/Magnesium low salinity test kit is suitable for measuring freshwater and brackish water with the salinity between 0 - 5 ppt. Review: Bought for Calcium and dissolved oxygen - I bought this because the three pack was cheaper than buying the dissolved oxygen and calcium together. They both seem reasonable accurate and are easy to ready and perform. I use them for my aquaponics system to check both the fish tank and the DWC beds to make sure everything has enough oxygen. ## Features - Dissolved oxygen test kit measurable range from 0 – 15 part per million (ppm) with the resolution of dissolved oxygen at 0.5 ppm.(60 tests) - Chlorine test kit me can be detectable at 0.1 part per million (ppm) for very chlorine-sensitive applications, for example in shrimp and fish hatchery. It is specially designed for low chlorine concentration between 0.0 – 2.0 ppm for general purpose and also detectable at high concentration up to 8.0 ppm for disinfection and water treatment application. (250 tests) - Calcium/Magnesium low salinity test kit is suitable for measuring freshwater and brackish water with the salinity between 0 - 5 ppt. Ca range from 0 – 200 part per million (ppm) with the resolution of 20 ppm per drop. Mg range from 0 – 960 ppm with the resolution of 12.15 ppm per drop. (120 Tests) - For freshwater and marine aquarium and aquaculture, pond water, ground water, drinking water - Easy to use, accurate, fast test, economic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6NSLFJ4 | | ASIN | B0B6NSLFJ4 | | Best Sellers Rank | #339,730 in Pet Supplies ( See Top 100 in Pet Supplies ) #463 in Aquarium Test Kits | | Brand Name | Generic | | Customer Reviews | 4.8 4.8 out of 5 stars (5) | | Date First Available | July 15, 2022 | | Date First Available | July 15, 2022 | | Item Package Dimensions L x W x H | 8.11 x 3.98 x 2.8 inches | | Item Weight | 15.8 ounces | | Manufacturer | JB CHEMICAL & PLASTIC Co., Ltd. | | Manufacturer | JB CHEMICAL & PLASTIC Co., Ltd. | | Package Dimensions | 8.11 x 3.98 x 2.8 inches; 15.84 ounces | | Target Audience Keyword | fish, shrimp, reef, water quality | ## Images ![Monitor DISSOLVED Oxygen, Chlorine, Calcium/Magnesium Low Salinity (Salinity 0-5 PPT) Test KIT_Combo Set - Image 1](https://m.media-amazon.com/images/I/61OpU4ALC0S.jpg) ![Monitor DISSOLVED Oxygen, Chlorine, Calcium/Magnesium Low Salinity (Salinity 0-5 PPT) Test KIT_Combo Set - Image 2](https://m.media-amazon.com/images/I/61s3tlq2VpS.jpg) ![Monitor DISSOLVED Oxygen, Chlorine, Calcium/Magnesium Low Salinity (Salinity 0-5 PPT) Test KIT_Combo Set - Image 3](https://m.media-amazon.com/images/I/71Gt0WAyZgL.jpg) ![Monitor DISSOLVED Oxygen, Chlorine, Calcium/Magnesium Low Salinity (Salinity 0-5 PPT) Test KIT_Combo Set - Image 4](https://m.media-amazon.com/images/I/71NRN4UTHlL.jpg) ![Monitor DISSOLVED Oxygen, Chlorine, Calcium/Magnesium Low Salinity (Salinity 0-5 PPT) Test KIT_Combo Set - Image 5](https://m.media-amazon.com/images/I/71p9sFeRvtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bought for Calcium and dissolved oxygen *by G***E on March 12, 2023* I bought this because the three pack was cheaper than buying the dissolved oxygen and calcium together.
