Introduction

Congratulations on your purchase of the Extech C010 Carbon Monoxide Meter. The
CO10 measures and displays CO concentrations between 0 and 1000 parts per million
(ppm).

Safety Information

Carbon monoxide is life threatening even at relatively low
concentrations; learn and recognize the effects of CO poisoning (see
Table below). Do not use this meter as a personal safety monitoring
device.

Effects of CO poisoning

0-1 PPM Normal background levels

9 PPM Maximum indoor air quality level

50 PPM Maximum 8 hour average exposure level

200 PPM Mild headache, fatigue, nausea and dizziness
