Key Features:
- Choice of sensor ranges to match application: ultra-low → low → extended
- Very low detection limits (down to 0.001 ppm / 1 ppb) for ambient monitoring
- Fast, stable response (typical T90 ≈ 60 s) with automatic baseline correction
- Interchangeable heads — swap sensors quickly with no re-configuration
- Active fan sampling for robust field performance (outdoor & indoor)
- Field and factory calibration options; recommended annual recalibration
- Compatible with Series 200 / 300 / 500 monitor bases (data logging, analog outputs, alarms)
- Lightweight, battery powered (up to ~8 hours), rugged for site surveys
