GENERAL DESCRIPTION:
The model GVU-VOC diesel smoke full spectrum sensor is designed
to interface with Toxalert International’s GVU series control units.
The GVU-VOC is a microprocessor-based air quality sensor utilizing
metal-oxide semi conductor technology. This is a full spectrum sensor
sensitive to a wide variety of air pollutants such as smoke,
hydrocarbons, gasoline fumes, acetone, toluene, etc. (see Table 3).
The GVU-VOC indicates its status with indicators for auto-power
on and processor normal, ok, low, mid or high for level of
contaminant detected.
BACKGROUND:
The diesel engine exhausts a great percentage of smoke (soot) as
well as, many hydrocarbons (e.g., ethylene, formaldehyde, methane,
benzene, and polynuclear aromatic hydrocarbons) and toxic gases
(e.g., nitric oxide, nitrogen dioxide and oxides of sulfur). The smoke
is particularly evident at the beginning of a work shift, when all
the buses or tracks are started in a maintenance/storage facility.
Even though, the exhaust smoke is not classified as a toxic, it is considered a carcinogen (reference:
carcinogenic effects of exposure to diesel exhaust - NIOSH Publication No. 88-116). Therefore many facility
owners are monitoring the smoke/hydrocarbons (VOC) as well as, the toxic oxides of nitrogen.
