Sensor-specific Calibration Notes
The following notes apply to specific sensor types during calibration. Follow standard calibration procedures unless otherwise indicated.
| Sensor Type | Calibration Notes |
|---|---|
| IR | Standard calibration procedure. No special handling required. |
| Electrochemical |
Standard calibration procedure. For COSH (CO+H₂S) sensors, calibrate CO and H₂S independently. Oxygen sensors (O₂) are typically calibrated using 18% Oxygen instead of bottled span gas. |
| PID | Calibrate PID sensor using Isobutylene from a separate gas cylinder |
| MPS | Factory calibrated at production. Manual calibration is not required and will impact measurement accuracy. |
