Disposable type aluminium calibration gas cylinders are available in 4 different cylinder sizes, which are 10 liter, 34 liter, 58 liter and 110 liter. To get gas out of the gas bottle or to regulate the outflow of the gas from the bottle, the right regulator is required. There are different types of regulators, and it may seem challenging to find out which regulator is needed. Choosing the right regulator depends on two things: (1) the type of gas detector (2) the size of the gas cylinder.

"Exposure of personnel to CO2 is a problem when producing soft drinks, producing beer and in the catering industry. Even a low concentration of CO2 such as 0.5% (= 5000 ppm) may be sufficient to become unwell. A CO2 concentration of 5% is deadly within 5 minutes."

hat are gas detector tubes, and how do you use them

"With a gas detector tube, you can detect the presence of a specific gas in the atmosphere. Gas detector tubes can be used to detect flammable gases, toxic gases and oxygen. The detector tubes consist of a sealed glass tube containing reactive chemicals coated onto inert support particles. Many gas sampling pumps contain a tube tip cutter. The tube tip cutter is provided on the gas sampling pump to break off both ends of the gas detector tube before you inserted the tube into the gas sampling pump."
