Introduction
Carbon Monoxide Meter
Instruction Sheet
The Carbon Monoxide Meter detects the presence
of
carbon monoxide
(CO) and measures concentrations between 1-1000 parts per million (PPM).
The Meter indicates the presence
of
carbon monoxide
in
two ways:
•
Bya
reading on the LCD
in
PPM.
•
Bya
beeper tone.
Safety Information-Read First
• Do not use the Meter as a personal safety monitor.
• Learn and recognize the effects
of
CO poisoning.
0-1
PPM
Normal background levels.
9PPM
ASHRAE Standard 62-1989 for living areas.
50 PPM OSHA enclosed space 8-hour average level.*
100 PPM OSHA exposure limit.*
200 PPM
Mild headache, fatigue, nausea and dizziness.
800 PPM Dizziness, nausea and convulsions.
Death within 2 to 3 hours.
*U.S. Department
of
Labor, Occupational Safety & Health Administration
(OSHA) Regulation 1917.24: The CO content
in
any enclosed space shall be
maintained at not more than 50 PPM (0.005%). Remove employees from
enclosed space if the
CO
concentration exceeds 100 PPM(0.01
o/~)
.
What the Meter Does
The Meter indicates the presence
of
CO by a reading on the LCD and a beeper tone.
The beeper functions much like clicking
of
a Geiger counter:
• Above 200 PPM, the beeper sounds continuously with the concentration
of
CO.
• From 35 PPM to 200 PPM, the beeper sounds discontinuously with the
concentration
of
CO.
