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.

Test principle
The gas in the sample is taken into the sensor, and the instrument calculates the ratio of O2 and CO2 (optional) in the gas by obtaining the signal output by the sensor. After reaching the test end condition, the test stops.
Test application
Packaging bags: Suitable for testing the content of O2 and CO2 (optional) in various non-negative pressure packaging bags such as coffee, cheese, milk tea, milk powder, bread, soy flour, modified atmosphere packaging, instant food, medicine, etc.
Packaging container: Suitable for testing the content of O2, CO2 (optional) in the gas in packaging containers such as canned coffee, canned milk powder, canned food, cheese, canned food, Tetra Pak, beverages, etc.
