The least count of a chemical dissolved oxygen reflux apparatus is usually determined by the precision of the measuring instrument used to detect changes in the dissolved oxygen levels in the apparatus. This can vary depending on the specific equipment being utilized, but generally, it is around 0.01 mg/L or lower.
When the Hoffman apparatus is used, the decomposition of water produces hydrogen gas at the cathode and oxygen gas at the anode. This process occurs as an electrolysis reaction where an electric current is passed through water to split it into its constituent elements.
The oxygen tank, or portable breathing apparatus, was invented by Emil von Behring in 1904. It was used to provide medical oxygen therapy to patients with respiratory conditions or during surgeries.
In an Orsat apparatus, Carbon Monoxide is absorbed by a solution of potassium hydroxide, Carbon Dioxide is absorbed by a solution of potassium hydroxide and pyrogallol, and Oxygen is absorbed by a solution of alkaline pyrogallol. Hydrogen is typically calculated by the difference in the volume of the sample gas before and after the absorption process. By measuring the volume changes in the different absorption bulbs, you can calculate the percentages of each gas component in the sample of producer gas.
An oxygen sensor is typically used to measure the concentration of oxygen in a gas. These sensors can be found in various devices such as oxygen analyzers, medical equipment, and industrial gas detectors. They work by generating an electrical signal in response to the presence of oxygen molecules.

A pulmonary apparatus refers to the organs and structures involved in respiration, specifically the lungs and associated tissues like bronchi, bronchioles, and alveoli. This apparatus facilitates the exchange of oxygen and carbon dioxide in the body.
In the Hoffman apparatus demonstration, the ratio of hydrogen and oxygen produced indicates the ratio of water's components (H2O). Since water molecule consists of two hydrogen atoms and one oxygen atom, the volume of hydrogen gas produced will be twice that of the oxygen gas when water is electrolyzed.
Back in 1924 oxygen tanks and the apparatus weighed a hefty 28LBS in weight for 3 Cylinders or 20LBS for 2 Cylinders. Today, 2014 1 Cylinder and apparatus weighs around 7/8LBS
