AIR QUALITY SENSOR MODEL AIR 3000

TYPICAL APPLICATIONS:

♦ Office Buildings (Commercial, Government,

FEATURES:

GENERAL DESCRIPTION:

The Model Air 3000 is a microprocessor-based air quality monitor utilizing metal-oxide semiconductor
technology. This is a full spectrum sensor sensitive to a wide variety of air pollutants such as Smoke,
Hydrocarbons, Benzene, Alcohols, Hydrogen, Esters, etc. The unit is temperature compensated and
effects from humidity are zeroed out.

This sensor is well suited to measuring overall air quality than a sensor which measures only Carbon
Dioxide. The AIR 3000 yields a true indication of the actual air quality, rather than occupancy. For
example, if a person were to smoke a cigarette in a room, the Carbon Dioxide sensor would be
inadequate for detecting this, even though the air quality has significantly degraded. This same set of
circumstances holds true for many other contaminants such as solvents, fuels, and even Carbon
Monoxide, all of which are much more harmful than Carbon Dioxide.

When measuring air quality, it is not so much the type of contaminant that is of concern, but rather the
presence of contaminants that is of concern. The sensor does not indicate what is contaminating the
air, but rather if and by how much it is being contaminated.

The Toxalert AIR 3000 sensor works by monitoring the signal from the full spectrum sensor, judges
the degree of pollution, and provides a configurable corresponding output signal. Configuration of the
output (analog signal, stepped analog, relay, etc.) can be customized depending on the application. For
the unit to perform efficiently it must work as a sensor/controller, i.e. must be able to act upon level
changes. The output is represented as a single 0 - 10 VDC output which has four user adjustable
settings, corresponding to clean, low, mid, and high levels. This output can be used to directly control
an actuator, or be sent back to a Toxalert controller, a computer, or a direct digital controller.

The AIR 3000 sensor can be configured to run auto or manual mode and has an integral sensitivity
adjustment to provide the user the optimum settings to monitor a specified area. There are internal
LED indicators to show microprocessor status and also a manual override feature to assist in installing
the unit.
