Det-Tronics 005434-004 (DE5434-004) is the replacement electrochemical sensor cell for hydrogen sulfide (H2S), 0 to 50 ppm range, used in the C7064E detector. The cell uses capillary diffusion barrier technology and is highly specific to H2S, with little cross-sensitivity to common gases.

Installation notes
- The cell is not field repairable; replace it when calibration can no longer be performed
- De-classify the area or remove power before replacing the sensor in a hazardous area
- Keep the cell in its sealed bag in a cool place until commissioning
- Check the hydrophobic filter (004532-002) before replacing the cell
- Calibrate 24 hours after power-up, one week later, then about every 30 days
The other C7064E ranges use 005434-003 (0 to 20 ppm) and 005434-002 (0 to 100 ppm). Scale the 4-20 mA input to match the cell range.
