Product Introduction The headspace gas analyzer adopts the destructive puncture detection method and is equipped with high-precision oxygen sensors and carbon dioxide sensors to accurately detect the O2 and CO2 content of hollow packaging containers such as packaging bags, bottles, cans, etc. The analysis of the content of the headspace gas in the packaging can make a reasonable judgment on the product quality, the validity of the shelf life prediction, and the rationality of the packaging design. At the same time, it can also be used as a means of packaging tightness testing. It is a better choice for modified atmosphere preservation (MAP, CAP) packaging, large infusion bottles (bags), residual oxygen in the headspace of prefilled needles, residual oxygen detection in vials, and the results of residual oxygen detection for various food and medicines. Nowadays, the headspace gas analyzer has become an important method to check the quality of packaging design and one of the important methods to verify the product shelf life. Our headspace gas analyzer GB-DK can quickly detect O2 in production lines, warehouses, laboratories and other occasions. And CO2 content to guide production.   Test principle The gas in the sample is drawn into the sensor by a vacuum pump. The sensor outputs the current and voltage signals of the O2 and CO2 (optional) concentration in the gas in the sample in real time. The instrument calculates the content of O2 and CO2 in the gas by obtaining the current and voltage signals output by the sensor. After reaching the end conditions of the experiment, the test stops, and the instrument records the concentration of O2 and CO2 in the measured gas in the sample.   Technical parameter Item Parameter Gas to be Measured O2 (standard configuration) CO2 (optional) Measurement Principle Fluorescence optics infrared absorption Measurement Range 0%～25% (for O2) 0%~100% (for CO2) Measurement Accuracy ±0.2% ±2% Sample Size ≥5 mL (at standard atmospheric pressure) (for O2) ≥20 mL (at standard atmospheric pressure) (for CO2) Dimensions 350 mm (L)×330 mm(W)×200 mm(H) Power Supply 220 VAC±10 % 50Hz/120 VAC±10 % 60 Hz Net Weight 5kg    Features 1.Using high-precision sensors, high accuracy, good stability, long-term operation, long service life.
