The Witt Gas Controls Oxybaby mobile gas analyzer requires a small amount of sample gas, around two millimeters for determining the oxygen or carbon dioxide content. The handheld unit uses dual pressure sensors for an accurate flow-rate control and to indicate the gas pressure in the packaging. The sensory needle is inserted in the packaging via a small sealing plate, and the measurement is ouput automatically in just a few seconds. With a measuring range between 0-100 percent and a display accuracy of 0.1 percent, all measured values are saved. The LED display has a white illuminated background, and the unit is supplied in a protective case that includes batteries, spare parts, consumable material and accessories.
