Made in India by Sarvesh Analytics. updated: 2026-11-03 source: html --- Industry # Gas analysers for fruit stores, food packaging and fermentation Shelf life is decided by the gas around the product. Fruit stores hold oxygen and CO2 at set levels, packers flush with nitrogen, and breweries blanket tanks with CO2. Sarvesh supplies the ACCURRA-S oxygen, trace oxygen and CO2 analysers for these jobs, built in Pune. Quick answer Sarvesh supplies ACCURRA-S oxygen, trace oxygen and CO2 analysers for controlled-atmosphere fruit stores, ripening rooms, food packaging gas and brewery tanks. They are gas-phase analysers; dissolved oxygen in liquids is not covered. Updated 3 November 2026 ยท Figures from Sarvesh datasheets What matters here ## What food, agriculture and cold chain plants need from gas analysis - Oxygen and CO2 for controlled-atmosphere and ripening rooms - Nitrogen purity as residual oxygen for packaging lines - Oxygen and CO2 checks on modified-atmosphere gas mixers - CO2 and trace oxygen for tank blanketing Food and cold-chain gas streams are usually clean, dry-enough and close to atmospheric pressure, which is a friendly condition for an extractive analyser. The decisions are about range and resolution: an ultra-low-oxygen store needs fine resolution near the bottom of the scale, while a packaging line mostly needs a trustworthy trace-oxygen reading on the nitrogen supply. Several ACCURRA-S models are supplied without an internal sample pump, so where the sample comes from a room or a tank at ambient pressure we confirm the sample path and add a pump where needed. Dissolved oxygen in liquids and oxygen left inside finished packs are different measurements and are not covered by these analysers. Applications ## Major applications in Food, agriculture and cold chain These are the applications we are asked about most, not the full list. We add more regularly, and we engineer for bespoke applications too. If yours is not here, contact us.

Ultra-low oxygen control needs fine resolution, so confirm the range and accuracy for your store, and allow for a sample pump on ambient sampling. **Can your analysers measure dissolved oxygen in beer or wine?** No. They are gas-phase analysers. They can check the CO2 or nitrogen blanket gas above the liquid.
