Brand: Erun
Desktop Fish Pond Aquaculture Water Quality Tester
number: ERUN-ST7
Parameters: PH, nitrite, ammonia, dissolved oxygen, etc.
ERUN-SP7, a portable fish pond aquaculture water quality monitor carefully developed and manufactured by Erun ERUN-ST7, a desktop aquaculture water quality tester developed and produced by Erun Environmental Protection Company, has a powerful data storage function, capable of saving up to 10 standard curves and 500 measurement results, and even in the event of a power failure to ensure that the data will not be lost.The instrument utilizes an imported high-performance, long-life light source combined with a highly stable optical system, which significantly improves the repeatability of the measurements.Designed for the aquaculture industry, the ERUN-ST7 is used to accurately measure key water quality parameters in aquaculture water, including pH, salinity, dissolved oxygen content, ammonia nitrogen concentration, nitrite content, and sulfide, to ensure that the water quality complies with established standards and to provide reliable water quality management support for aquaculture.
