Overview
The carbon dioxide Dioxcare detector detects
the carbon dioxide gas of the onsite environment
through absorption principle of infrared light sources.
The product has the characteristics of
temperature, humidity and CO2 tendency chart,
999 groups of data record, 3.2″TFT full color
display, alarm setting, data record of time interval
measurement, real-time date and time, chargeable
lithium battery or separate external USB charging.
The application eld of carbon
dioxide detector:
1. Public site
The densely populated place such as meeting
room, classroom, exhibition hall, hospitals,
department stores, bars, hotel, airport, railway
station and entertainment hall, etc. the carbon
dioxide detector may be used for ventilation
control and environment quality monitoring So,
it is used to guarantee body health.
2. Agriculture
The carbon dioxide may be used for plant
photosynthesis. Therefore, it is widely used
for agriculture. The air fertilizer with proper
concentration may improve output of agricultural
crops. When the concentration of carbon dioxide is
not sucient, air fertilizer may be used. It will give
great help for whether the vegetable growth or
improvement of vegetable.
3. Animal husbandry
The air quality concerns healthy growth of
animals. If the air is turbid for a long time and
the concentration of carbon dioxide is high and
ventilation is not provided, the animal will get ill
or epidemic disease may burst out. Therefore,
installation of carbon dioxide detector at livestock
farm may prevent occurrence of animal epidemics.
ENGLISH
4. Industry
The carbon dioxide detector is widely used in
the Industry such as wastewater treatment,
factory building, workshop, temperature,
cleaning room, production safety and all types
of Industries. Especially, it is very necessary to
monitor the carbon dioxide in borehole operation.
The carbon dioxide detector is used generally in
metal processing, paper pulp and paper making,
cleaning and solvent extraction as well as lower
temperature cleaning and carbon dioxide
relevant Industry.
Safety and maintenance
1. It is recommended to do a manual calibration
before starting to use the CO2 meter so that it
will perform the measurements correctly.
2 .Please do not use the meter under a dusty or
corrosive gas environment so as not to result in
shorter service life or damage.
3. When the battery icon on the display screen is
blank or red, please charge the battery in a timely
manner. When it lies idle for long, it is required to
take out the battery.
4. Please do not store or use the meter under
a high temperature, high humidity, ammable,
explosive and strong electromagnetic eld.
5. During the care of it, please use soft cloth and
neutral cleaning agents to clean the housing.
Never use abrasives or solution so as not to cause
corrosion to the housing and damage to the meter.

Warning: Device has been calibrated at the factory, however it is highly recommended to do a
manual calibration before starting to use it. The user can calibrate it periodically if desired. The rst
time the CO2 Sensor can take up to 10 days to fully balance and present accurate data. Calibration
must be carried out in an outdoor environment.

Carbon dioxide concentration level
400-450PPM (excellent) usual outdoor air level.
450-700PPM (Good) The typical value of living
space with good ventilation. 700-1000PPM
(Minor pollution) The living environment with poor
ventilation.
1000-2000PPM (middle level pollution)
insucient oxygen makes people sleepy and
the air that may cause complaint.
2000-5000PPM (serious pollution) The stagnant,
old and muggy air. The phenomenon of headache,
drowsiness with distraction, declination of
attention, tachycardia and slight nausea.
Above 5000PPM (serious pollution) may cause
serious anoxia or lead to perpetual cerebral injury,
coma or even death when exposing in air.
Above
5000 PPM
ENGLISH
Analysis of commonly seen troubles
1. The carbon dioxide concentration data
in the air is not accurate.
Analysis 1: The concentration content of the
environment is not stable. At the time of measurement,
place the device in the same place
for a period of time.
Analysis 2: There are sundries, dirt at the sampling
window of carbon dioxide sensor. The air ow
ventilation window is blocked.
Analysis 3: the carbon dioxide sensor has deviation. It
needs to calibrate the equipment again.
2. Incorrect temperature and humidity
Analysis 1: Analysis of existence of impurities or dirt
or lth at the sampling window of the temperature and
humidity sensor.
Analysis 2: The ventilation window has been blocked
by something.
3. Date and time is not accurate
Analysis 1: caused by too low button battery level
inside the equipment.
4. Failure in power on
Analysis 1: The battery has no power or is damaged.
Use the USB socket for power supply. If power can be on,
and if there is change any change in the power check, it
indicates that there is no power in the battery. If there
is no change, the OK icon is displayed only indicating the
battery has been damaged.
Analysis 2: Battery +/- polarity is mounted reversely. It
is required to note that the non-protruding contact at
one end of the battery must be “-” polarity, and that the
protruding contact at one end must be “+” polarity. The
following gure can be referenced.
