PH/ Dissolved Oxygen/nitrite/ammonia Nitrogen/toxic Ammonia/temp The Six-in-one Water Quality Detector Is Specially Designed For Aquaculture
KNF-200 is a specialized water quality detector for aquaculture, with multiple detection items to help you better understand the aquaculture environment. It comes standard with a complete set of reagents, an external dissolved oxygen probe, and a water sampler design suitable for various fields such as freshwater/seawater aquaculture, shrimp farming, and experimental research.
Main features:
•Six indicators can be detected: pH/dissolved oxygen/ammonia nitrogen/nitrite temperature/toxic ammonia
•Support for data storage (99 transactions)
•Equipped with compensation function (poster/salinity/temperature compensation)
•4 AAA batteries (continuous use for 3-4 hours)

Application scope:
Aquaculture/Shrimp Factory/Fish Pond Farming/Seawater Farming
Sewage treatment plant
Laboratory testing
River water quality inspection
Agriculture and other fields
