Deciding which fertilizer to use can be overwhelming, but with a bit of knowledge you can be sure your garden will get the right amount of nutrients it needs. The first question you’ll need to answer is, “What analysis do I need?” The analysis is actually three numbers you see usually at the middle or bottom of fertilizer packages (for example 10-20-10). These numbers represent percentages of the three major nutrients plants need: nitrogen, phosphorus and potassium (NPK for short).
HI 83215 is a multiparameter bench meter that measures twelve methods in low, medium and high ranges essential for monitoring greenhouse and hydroponics operations. It’s three channels allow for a wide range of tests.
The optical system of HI 83215 is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.
HI 83215 has powerful interactive user support that assists the user during the analysis process. A full tutorial is available in the Setup Menu, and the Help Menu provides assistance for every step in the measurement process. This meter can be connected to a PC via a USB cable, where the data can be managed with optional HI 92000 Windows® compatible software.
