The potassium hydroxide concentration Hydrometer adopts anti-corrosion liquid density test accessories, which is suitable for measuring the density, Baume degree and concentration of corrosive and non corrosive liquid with fluidity. It is commonly used to detect the density, Baume degree or concentration of PCB circuit board waste liquid, petroleum, gasoline, diesel, urea, potassium hydroxide, urine, ethanol, sucrose, essence, perfume, cosmetics, makeup remover and other liquids.
Calculation formula of potassium hydroxide density
The measuring principle of the potassium hydroxide concentration meter is the Archimedes buoyancy method, also known as the liquid immersion method. The instrument automatically passes through a known density ρ The mass m1 of the specific gravity hammer in the air and its floating weight m2 immersed in the liquid to be measured are calculated by combining the density calculation formula with the buoyancy calculation formula to obtain the density calculation formula of the liquid to be measured: ρ= (m1 m2) ρ 1/m1; The built-in software of the potassium hydroxide concentration detector has integrated the calculation formula of density, Baume degree and potassium hydroxide concentration, which can achieve the function of obtaining the density, Baume degree and concentration value of the sample in a single measurement.
During the measurement process, there is no need for manual calculation. At the end of the test, the instrument automatically displays the density value of the sample. Press Mode to switch to the Baume degree and concentration of the sample. The measurement of Baume degree and concentration of liquid by potassium hydroxide densimeter is based on the measurement of liquid density. Baume degree is divided into light Baume and heavy Baume, and is linearly related to density.
The linear relationship can be simply understood as y=ax+b, where the values of a and b are known. The built-in program of the electronic densitometer will independently choose the formula of light or heavy wave based on the obtained density specific gravity value for calculation. To measure liquid concentration, it is necessary to first determine whether the density and concentration of the liquid to be measured can satisfy a linear relationship, and to know the corresponding calculation formula.
The relationship between the concentration and density of potassium hydroxide is y=100.1x-98.942, where a=100.1, corresponding to E2 in the software; B=-98.942, corresponding to E1 in the software
Usage of potassium hydroxide concentration meter
After simply installing the support plate and measuring bracket, hang the stainless steel hook on the measuring bracket and reset it to zero; Under the condition of 0.000g of the instrument, hang the Teflon specific gravity hammer on the hook, take a cup of liquid to be measured about 50ml and place it on the support plate, then move the cup containing the liquid to be measured, immerse the specific gravity hammer in the liquid to be measured, after the weighing value is stable, press the Enter key, the instrument will automatically calculate and display the density value of the sample, and press the Mode key to switch the Baume degree and concentration value of potassium hydroxide solution.
