FC7-H2-1000 — different hydrogen scale
FC7-H2-1000 should be evaluated as its own electrochemical hydrogen-sensor model, separate from the FC4-H2-20000 line. Those part-number suffixes should not be taken as verified measuring ranges unless the current Shenzhen ProSense data sheet explicitly defines them. Confirm sensitivity, measurement range, interfering gases, analog conditioning and calibration. Sensor-electrode lifetime and the housing’s environmental compatibility are relevant to industrial pipe-gallery leak monitoring; the bare cell is not a certified complete alarm.
FC7-H2-1000 — specific electrochemical hydrogen cell
| Measurement | Hydrogen (H₂) 0–1,000 ppm; maximum overload 2,000 ppm. |
|---|---|
| Sensing and sensitivity | Micro fuel cell, 0.4 ±0.2 nA/ppm nominal; this is a bare current-output component, not a 4–20 mA or digital transmitter. |
| Response and stability | T90 under 60 seconds; ±10 ppm baseline at 20°C; ±20 ppm zero drift over −20…+40°C; repeatability 2%; manufacturer claims less than 3% signal drift per year. |
| Operating environment | −40…+70°C, 90–110 kPa, 10–90% RH. |
| Lifetime and construction | 5-year service life, 24-month warranty, approximate sensor weight 12 g. |
Integration caution: Do not infer that the model suffix defines instrument safety certification. Bare FC7-H2-1000 requires a calibrated analog readout and an approved complete gas detector design. The FC-H2-1000 is another model with different sensitivity/lifetime; values are not interchangeable.
