- Patented DD (double detector) catalytic bead sensor – fast response times, low drift, long life, low cross-sensitivity, best resistance to poisoning
- Catalytic DD sensor available as either 0-100% LEL of 0-10 % LEL for low detection limits
- Single and dual beam IR (infrared) sensors can measure hydrocarbons or carbon dioxide in either % LEL or ppm
- Dual beam IR sensors have a 5 year warranty, are water proof, and only need an annual reference check (no calibration requirement)
