ToxiPro Replacement Sensors
ToxiPro Replacement Sensors; fresh Honeywell OEM sensors for your ToxiPro. Carbon monoxide (CO), hydrogen resistant carbon monoxide (CO-H), hydrogen sulfide (H2S) and oxygen (O2) sensors have a 2 year shelf life from date of manufacture; ammonia (NH3), Chlorine (Cl2), hydrogen cyanide (HCN), nitrogen dioxide (NO2), phosphine (PH3), chlorine dioxide (ClO2) and sulfur dioxide (SO2) have a one year shelf life.
Sensors are readily replaced in the field by removing the back cover, removing the expired sensor by lifting sensor straight up. Replace the old sensor with the new sensor and any needed dust filters. Replace the back cover and turn on the ToxiPro, letting it stabilize in “clean air”. The oxygen sensor can be span calibrated in clean air, other challenge gasses require calibration gas of known concentration.
