GENERAL DESCRIPTION
The SENSIT® CO is a hand held carbon monoxide analyzer. The base
model is designed to provide part-per-million (ppm) readings of levels of
CO within a range of 0-2000ppm.
The instrument is available with an optional oxygen sensor which
provides the percent of oxygen in air within a range of 0-25% volume.
Additionally, an Air-Free CO feature is available on the CO/O2 version.
With this optional feature, the instrument will calculate the elevated levels
of CO related to increasing oxygen levels detected in appliance ue gas
emissions. This information is presented in PPM as “CF” on the display.
All model options can be specied at the time of ordering or base models
can be upgraded by the factory or authorized service center with the
required hardware and software additions.
The sensors are electrochemical, which can be eld calibrated. The
sensors have a renewable lter which reduces cross-sensitivity and are
economical to replace. By using the supplied hot air probe the instrument
can evaluate CO and O2 levels from appliance ues or vents.
The SENSIT® CO models can also be used as a personal monitor.
The default factory alarm set point for carbon monoxide is 35ppm. The
optional O2 sensor default factory alarm set points are less than 19.6%
or greater than 23.5%. The display must be in view to determine the
detected CO and O2 levels.

PRODUCT FEATURES
SENSIT® CO instruments are constructed of high impact ABS plastic
to withstand the rigors of eld use. Incorporated in the hand grip area is
the battery compartment.
All SENSIT® CO instruments models operate on “C” type alkaline
batteries or NiMH (nickel metal hydride) batteries. The approved
batteries are, PROCELL MN1400 Alkaline or equivalent and the
PANASONIC HHR300CH NiMH battery or equivalent.
The two line LCD continually updates PPM CO levels for the base
model, percent oxygen level is added for the CO/O2 model and PPM
“CF” is included for the CO/O2/air-free CO model. Regardless of the
model, all instruments display all data simultaneously on the LCD when
in the work display.
All models use a diaphragm pump to draw in the air samples. Flow
block, low battery power and sensor failure alert will appear on the LCD
as needed.
Warning systems for the operator consist of one audible alarm, omitting
a tone from the speaker on the back of the instrument and two visual
indicators on the front. One is a red ashing LED alarm light, the other
is a ashing gas or optional oxygen reading on the LCD when the
instrument detects readings at the alarm set point. All alarms indicate
simultaneously unless the operator chooses to use the audible alarm
mute feature.
An infrared communication window is located on the right side to
permit downloading of calibration data, data saved by the operator
and communication with the Smart-Cal Calibration Station and PCI2s
computer interface.
