H2S/CG-10000 — high-span electrochemical biogas cell — technical model review
Source-specific manufacturer specifications, test conditions and practical engineering distinctions. The stated model/range is not a blanket safety approval or a guarantee that related part codes perform identically.
| Parameter | OEM documentation | Engineering interpretation |
|---|---|---|
| Working principle | Three-electrode electrochemical H₂S sensor, compact gas-tight housing | Requires an appropriate potentiostat/analog amplifier; no built-in Modbus or ppm screen. |
| Nominal span | 0–10,000 ppm H₂S | Distinct from common 0–10 or 0–100 ppm personal H₂S alarm cartridges. |
| Maximum overload | 20,000 ppm H₂S | An overload survival statement is not a calibrated 20,000-ppm measurement range. |
| Current sensitivity | 15 ±5 nA per ppm H₂S | Host electronics and calibration determine the usable reading. |
| Resolution / response | Less than 3 ppm electronics dependent; T90 less than 35 seconds | Resolution alone makes it unsuitable to infer dependable sub-ppm safety thresholds. |
| Baseline | −60 to +60 ppm equivalent in clean air at 20 °C | Check offset and zero compensation for lower-concentration applications. |
| Working conditions | −40 to +50 °C; 15–90%RH noncondensing; atmospheric pressure ±10% | Biogas condensation/pressure and sample conditioning must stay within limits. |
| Life / storage | Expected 2 years in air; 6 months storage in container; 10–33 Ω suggested load | Plan calibration/spares rather than asserting long-term drift-free use. |
Installation, electronics and calibration
The model is valuable for discontinuous sampling or biogas analyzer duty because its 10,000-ppm span tolerates concentrations well above normal occupational monitoring ranges. Include sample-line drying/condensate control, a suitable material seal and offset compensation. Membrapor’s own sheet makes performance claims at 20–25 °C, 30–50%RH and 900–1100 mbar and states that the specified resolution depends on the electronics. A bare sensor does not satisfy worker alarm certification merely because the leaflet includes safety/process use cases. Review cross-sensitivity tables before calibrating with blended biogas.
