TES ELECTRICAL ELECTRONIC CORP.
I. SAFETY INFORMATION
Safety
When using the meter to check for CO
2
values, make certain
that you can safely raise and hold the instrument while making
measurements. Be especially careful when working on a ladder.
Observe all necessary precautions so that the unit does not become
caught in moving machinery or touch any exposed electrical wiring.
Ventilation systems should be designed to bring in enough
outside air to keep the ambient air below 1,000 PPM CO
2
. CO
2
comes from people exhaling CO
2
in the concentration of
approximately 40,000 PPM. The more people in a room or
building, the more CO
2
is present.
Unlike CO (carbon monoxide), people can sense CO
2
. As CO
2
levels go up, people can become unproductive, irritable,
uncomfortable and tired.
The way to bring CO
2
levels down is to bring in more outside air.
ASHRAE Standard 62-1989 contains guidelines to determine
ventilation rate by measuring CO
2
content of air. If CO
2
is higher
than 1,000PPM, ventilation system modifications may be
necessary to insure IAQ conditions are met as established by
ASHRAE.
Danger
Use with corrosive or other dangerous or explosive gas
mixtures is not recommended.
