Summary
Product Identification
Aeroqual VOC Sensor Head
Technology
Uses gas sensitive semiconductor technology.
Key Features
- Rapid response
- High sensitivity
- Excellent accuracy
- Long-term stability
- Low drift
- Excellent temperature and humidity stability
- Minimal maintenance
- On-board "sensor failure" diagnostics
- Custom calibrations and cross-sensitivity tuning available upon request
Sensor Head Lifecycle
- Warranty: 6 months
- Expected life: > 5 years
- Recommended calibration period: 12 months
- Shelf life: Can be stored for > 5 years in a clean, dry environment between 0 to 50°C.
VOC Detection
- Responds to a wide variety of volatile organic compounds.
- Particular sensitivity towards oxygenated hydrocarbon compounds.
- The standard VOC Sensor Head is pre-calibrated to isobutylene.
- Correction factors are available to quantify a range of other gases.
- Default concentration reading is in ppm of Isobutylene.
- To convert to ppm of another gas, multiply the reading by the gas's correction factor (CF). Example: 10 ppm Isobutylene x 1.7 (Heptane CF) = 17 ppm Heptane. Accuracy of correction factors is < ± 30%.
- Can be used to qualitatively indicate total VOC level in ppm Isobutylene equivalent.
