- Office buildings, schools, hospitals,
apartment buildings, churches and synagogues, homes, any place
where a large number of people (or animals or plants) are present
can have elevated levels of carbon dioxide (CO2). Headaches,
irritability, fatigue, difficulty in breathing, increase in the
breathing rate and/or pulse rate, sweating, shortness of breath,
and a feeling of "stuffiness" are common symptoms of
breathing air with higher than normal CO2 levels. Our
Model 300 Series Carbon Dioxide detectors are the easiest way
to continuously check CO2 levels and provide data to maintenance
personnel in order to adjust HVAC ventilation rates, make occupants
of buildings more comfortable and supply healthy fresh air. The
300 Series units can be used immediately, right out of the box,
to help you meet OSHA's Indoor Air Quality (IAQ) standards and
American Society of Heating, Refrigerating, and Air Conditioning
Engineer's (ASHRE's) ventilation standards. Occupants and building
management both benefit. Improve the indoor air quality in your
facility with the help of the economical 300 Series Carbon Dioxide
Monitors. Together with one of our Kidde Nighthawk digital readout
carbon monoxide alarms you can economically and accurately monitor
two of the most common indoor air contaminants in your indoor
environments.
-
- Housed in a sleek new case,
our new generation Model 310 is the first choice for building
ventilation system professionals. With an unprecedented 1 year
warranty and only one cal gas required for calibration (rather
than zero and cal gas) the 310 is the user-friendly CO2
monitor you need.
-
- The 310 and the 301A are the
cutting edge of infrared technology: Excellent long-term drift
performance is enhanced by a new, improved, more stable IR source,
a new state-of-the-art lithium tantalate detector, updated digital
electronics and unique auto-zero function. This results in very
stable calibration and longer trouble-free operation in the field.
The new IR source is more rugged, operates at 10X derated power
and has a life expectancy of at least 15 years (and its own five
year warranty). The new lithium tantalate detector enhances stability,
has less ambient temperature sensitivity, and faster response
time.
-
- Fail-safe design means the electronics
cannot be damaged if the power is accidentally hooked to the
wrong terminals. Each unit is electronically isolated so that
multiple units can be connected to the same controller without
electronic interference.
-
- The 300 Series units are extremely
versatile, with digital display, and 115 V. power options available.
The units have both voltage and 4-20mA outputs. The new smaller
size with power consumption as low as 60 mA and .8W make it ideal
for battery-operated portable applications.
-
- Patents are pending.
