The vens multi-gas meters offer 4- or 5-gas monitoring of toxic gases, oxygen (O2), combustibles (LEL), carbon dioxide (CO2) and volatile organic compounds (VOCs). The vens VOC is an advanced model with built-in pump that allows a full selection of sensors for a wide range of applications, including Confined Space Entry, while
the vens voc is a basic, 4-gas diffusion detector for worker safety at hazardous locations. Smart sensors carry
calibration and ID information with them for quick exchange in the field during Hazmat response. Specific sensors
include electrochemical (EC) for carbon monoxide (CO), hydrogen sulfide (H2S), ammonia (NH3), hydrogen cya-
nide (HCN), hydrogen chloride (HCl), chlorine (Cl2), chlorine dioxide (ClO2), nitric oxide (NO), nitrogen dioxide
(NO2), sulfur dioxide (SO2), ethylene oxide, methyl mercaptan, and others. Also available are pellistor for LEL level
combustibles, non-dispersive infrared (NDIR) for Vol% level CO2 or methane, and photo-ionization detector (PID)
for ppm level VOCs. Use of combination CO/H2S or SO2/H2S sensors allow up to 5 gas measurements in a single
instrument. The voc has rugged construction and easy-to-learn 2-button operation. The unique Man-
Down alarm feature notifies team workers wirelessly if a user becomes incapacitated.
