|4 GAS, CONFINED SPACE ENTRY PORTABLE
Model IQ-200 requires just two sensors for confined space
entry applications, a single solid state sensor for CO, H
2 S, and combustible gases, and an electrochemical sensor
for oxygen. This makes the IQ-200 much more affordable than
space entry portables. Additionally, both the solid state
and oxygen sensors used in the IQ-200 are long-life sensors.
Typical life expectancy is 5 years for the O 2 sensor and
over 10 years for the solid state sensor. This results in
a tremendous savings in long term operating costs associated
with sensor replacement.
IQ-200 has an audible alarm buzzer, and alarm LEDs indicate
low, mid, and high alarm levels for the solid state sensor,
and low and high alarms for the O 2 sensor. The IQ-200 does
not incorporate a sample pump and samples by diffusion only.
It is small and lightweight, weighing just 22 ounces, including
batteries. It operates on 4 size AA alkaline or
nicad batteries, or the AC adapter/charger. Carrying case
