The LTDK-190 headspace gas analyzer adopts a new handheld design and is equipped with imported sensors, which can accurately and conveniently determine the O2 content in sealed packaging bags, bottles, cans and other hollow packaging containers; the CO2 content can be tested by the optional sensor. Allows you to quickly and effectively test modified atmosphere packaging, which is a necessary condition for mass brand manufacturing. The operator can see at a glance whether the gas composition is within the required level. It also has the traceability you need: the basic data of each package can be stored in the device itself or transferred to the LTDK-190 software or third-party software.
