by offering better drift and temperature
compensation, in addition to a redesigned
enclosure built to enhance airflow and an
improved backlit display (optional).

Installation, connection and use of the 90DM4 are
virtually identical to the 90DM3A. With the same
state-of-the-art microprocessor controlled CO2
monitoring coupled with refined performance,
the 90DM4 is the top choice for monitoring CO2
levels in schools, offices, or any other commercial
application.

Mounting Made Unique and Easy

To provide maximum versatility, the 90DM4 is
available with two different housing configurations,
making it ideally suited to virtually any commercial or
industrial gas detection application. Both enclosures
are made of ABS plastic, offering maximum
durability.

Designed to accurately detect the presence of CO2
in air-handling systems, the DT Model represents
a radical innovation in housing design. Unlike other
units on the market today, the enclosure is totally
airtight, more compact, and extremely lightweight,
with a convenient mounting bracket to improve
installation. All in all, its superior operational and
cost efficiency make the DT Model the only choice
for larger-scale CO2 detection applications.

The SM Model is a wall-mounted unit with a
compact and an aesthetically pleasing design
which blends perfectly and discretely with any
room decor. Easily installed directly onto drywall or
other surfaces, the SM Model ensures superior gas
detection.
