Introduction; Key Features - General VOC08 Hardware Manual

INTRODUCTION

Thank you for purchasing General Tools & Instruments'
VOC08 Data Logging VOC Meter. Please read this user's
manual carefully and thoroughly before using the product.
The VOC08 is an easy-to-use handheld instrument for making
ballpark measurements of mixed-gas volatile organic
compound (VOC) levels as part of an indoor air quality (IAQ)
maintenance program. Examples of VOCs include cigarette
smoke, ammonia, ethanol, and the low levels of toluene
produced during wood finishing and construction products.
Why does the VOC08 lack a VOC accuracy specification?
Because it can only measure the total concentration of VOCs
contributed by multiple gases, rather than the concentration
of a single gas. VOC meters that use photo-ionization
detection (PID) technology and ultraviolet lamps to break
down single-gas VOCs into ions are faster and more accurate
than the VOC08, but they cost at least 10 times more. The
VOC08 is therefore a much more suitable solution for home
inspectors and facilities managers who only need to spot-
check concentrations of mixed-gas VOCs.

KEY FEATURES

• Metal-oxide semiconductor sensor within vented ball
housing detects ammonia, toluene, ethanol, hydrogen
sulfide (H 2 S) and cigarette smoke
• Makes ballpark measurements of total VOC concentration
as well as accurate measurements of ambient temperature,
relative humidity (RH), dew point and wet bulb
temperatures
