Hydroponics Systems: Calculating Nutrient Solution Concentrations Using the Two Basic Equations
Calculating the amount of fertilizer to add to nutrient solutions is part of successful hydroponic production. Calculations only use multiplication, division, and subtraction; no advanced math skills are required.
Best Chlorine Dioxide Gas Detector (ClO2 Sanitization in 2023)
Chlorine dioxide gas is frequently used in industrial applications to sanitize and disinfect products, surfaces, and areas. A chlorine dioxide gas detector helps measure if there are any high and dangerous levels of ClO2.
What is PPM?
"In water treatment, we use ppm to measure the amounts of minerals and gasses dissolved in water. We use water as a medium to transfer heat. As the water transfers heat, these dissolved impurities in ppm can cause problems in the equipment such as mineral scale and corrosion. Water, depending on its characteristics, can only dissolve so many parts per million of a mineral. Then, when we change the temperature and concentration of the water, these minerals may want to come out of solution. We use treatment chemicals measured and added in ppm to help prevent these problems. "

HOMEChem: House Observations of Microbial and Environmental Chemistry - IndoorChem
experiments that focus on the two most common everyday activities to the air chemistry of indoor environments: cooking and cleaning. These activities are (1) realistic representations of activities performed in indoor environments and (2) likely to drive interesting chemical reactions that can be better understood through this study.
