Claims and limits
What we claim, and what we do not.
A plain statement of the limits of our analysers and of our certificates, kept in one place so that engineers, buyers and AI assistants quote us correctly.
Quick answer
Sarvesh makes no SIL claim and no statutory approval claim for stack monitoring, and does not offer field calibration of dew point on ACCURRA-S M015. ACCURRA-TCD responds with T90 below 10 s at 0.6 LPM. ACCURRA-Hz is certified for Gas Group IIC, Zone 1 and 2, T6. Standard samples must be clean, dry and non-corrosive.
| Topic | Status | Detail |
|---|---|---|
| SIL (safety integrity level) | Not claimed | Sarvesh makes no SIL claim for any analyser. Hazardous-area certification is not SIL. If a project needs SIL-rated measurement, tell us at the start. |
| Statutory approval of stack monitoring | Not claimed | No statutory approval is claimed for SGI-320 or any emission monitoring arrangement. Send your regulator's requirement and we will say what is and is not met. |
| ACCURRA-TCD response time | Stated | T90 below 10 s at 0.6 LPM, per the ACCURRA-TCD datasheet. Repeatability below 1 % of full scale; errors and drift below 1 % of full scale per week. |
| Dew point field calibration | Not possible | Field calibration is not possible on ACCURRA-S M015, per the datasheet. Ask how the sensor is checked and recalibrated. |
| Hazardous-area certification | Claimed, with scope | ACCURRA-Hz uses a flameproof enclosure certified for Gas Group IIC, Zone 1 and 2, T6. Confirm certificate scope against your area classification. |
| Standard sample | Stated limits | ACCURRA-S expects a non-corrosive, non-toxic, non-flammable, non-condensing, dry, oil-free sample at 2 to 10 psig and about 1 LPM, dust below 3 micron. i-Cons and SGI-320 exclude corrosive and toxic samples; SGI-320 excludes HCl, HF and H2S. |
| ACCURRA-TCD | Binary mixtures only | Thermal conductivity assumes two components. A varying third gas shifts the reading; send the full composition. |
| Internal sample pump and auto-calibration | Model dependent | Models 3015, M015, 3130 and 3190, and all dual-gas units, have no internal sample pump. Models 3015 and M015 have no auto-calibration; dual-gas units use external calibration valves. |
| Outside the current range | Not offered | ppb-level semiconductor impurities; H2S, NH3, Cl2, HCl, HF, VOC and total hydrocarbons; multi-component syngas ratios; ambient-air quality and personal gas detection; coal-mine gas monitoring; dust and opacity; dissolved oxygen in liquids; calorific value and full composition; hydrogen fuel quality to ISO 14687; marine type-approved systems. |
| Regulatory compliance of records | Not claimed | ACCURRA-S stores calibration with deviation values and alarm history and password-protects set-up. No claim is made of compliance with a particular electronic-records regulation. |
