Left to right: weighing 100 mg of NaCl; 100 mL of NaCl solution; measuring concentration using TDS-3 meter As you can see in the picture, TDS-3 measures 955 ppm. The conductivity of this solution should be 1000 ppm / 500 = 2 mS/cm (NaCl or 500 scale). Measuring the resis...
The concentration is all the same whether we use the %LEL scale, the percent scale or the ppm scale. 100% LEL = 5% methane = 50,000 ppm methane 10% LEL = 0.5% methane = 5000 ppm methane 1% LEL = 0.05% methane = 500 ppm methane So here we have three numbers ...
