Sarvesh supplies ACCURRA-S 6030, 3015, built in Pune, with sampling matched to the stream. - ISO 9001:2015, certified by TÜV - Designed and built in Pune since 2002 - Supplied to Reliance, Tata Steel, Indian Oil, Linde and ISRO Quick answer Use ACCURRA-S 6030 (CO2 up to 100 %), 3015. Beverage and dry-ice CO2 is sold on purity; trace oxygen is a typical limit. Sample must be dry and free of oil; add conditioning for process streams. Updated 2 November 2026 · Figures from Sarvesh datasheets ## The measurement and why it matters Beverage and dry-ice CO2 is sold on purity; trace oxygen is a typical limit. This application matches the catalogue specification directly. Industrial gas producers, distributors and users all buy and sell on a purity figure. A reading taken continuously, at the point where gas changes hands or enters a process, lets a plant release a batch with confidence instead of waiting for a laboratory result. Most gas-handling streams are clean, dry and pressurised, which suits the ACCURRA-S sample specification. The points to settle are usually the sample path (vaporised, regulated and vented safely) and whether the stream is a binary mixture, which is the condition for ACCURRA-TCD. Typical buyers in India: CO2 gas producers, dry-ice makers, beverage fillers. Where this matches your plant, send us the gas, range, pressure and temperature at the tapping point and we will confirm the analyser and sample path. ## Models and ranges | Model | Measures | Range | Sensor and notes | |---|---|---|---| | 6030 | Carbon dioxide | 0 to 20 % or 0 to 100 % | NDIR | | 3015 | Trace oxygen | 0 to 1000 ppm (min range 0 to 100 ppm) | Electrochemical; no internal pump, no auto-calibration | ## Process notes ### What the analyser reads here Gases of interest: CO2, O2 ppm. Analyser fit: ACCURRA-S 6030 (CO2 up to 100 %), 3015. The table above lists each model with its range; where a row says to confirm the range, we check it against the datasheet for your application before quoting. ### What to settle before ordering Sample must be dry and free of oil; add conditioning for process streams. We would rather confirm these points at the start than discover them at commissioning, so please include them with your process details. ## Sampling and installation - Every ACCURRA-S has an internal fine filter and rotameter. Regulate sample pressure and flow externally; the catalogue recommends about 1 LPM and a sample pressure of 2 to 10 psig. - Models 3015, M015, 3130 and 3190 are supplied without an internal sample pump. Tell us the sample pressure and we will confirm the sample path or add a pump. - Models 3015 and M015 have no auto-calibration, so plan a calibration routine with the right reference gas. - Keep sample lines short, clean and dry, and vent the sample somewhere safe. ACCURRA-S sample specification: non-corrosive, non-toxic, non-flammable, non-condensing and dry, free from entrained oil; sample pressure 2 to 10 psig, regulated externally; flow about 1 LPM; dust below 3 micron. Where your sample differs, we design conditioning around it. ## Send us your process data **What the data sheet asks for** Send what you have and we will ask for the rest. - The gases to measure, the range, and the accuracy you need - Background gases and their typical composition - Sample temperature, pressure and dew point at the tapping point - Dust level, and whether the gas carries tar, oil or condensable vapour - Process connection and, for ducts, the duct diameter - Where the sample vents to, and at what pressure - Area classification of the tapping point and of the analyser location, and the IP protection needed - Distance between the tapping point and the analyser - Outputs you need: 4-20 mA, dual range, relays, Modbus RTU - Calibration approach, calibration gas available, and whether blowback is required - Utilities at site: power supply, instrument air, nitrogen, steam and cooling water, and the ambient temperature range - Gases and ranges: CO2, O2 ppm - The point to confirm: Sample must be dry and free of oil; add conditioning for process streams. ## Recommended Sarvesh products [ ### ACCURRA-S Trace, percent and purity analysis of O2, CO, CO2, CH4 and dew point.
