CarbonMonoxideMeter
Instruction Manual
Version: 8805-EN-OO
I. Introduction
Purecarbonmonoxide(CO) is colorless, odorless,
and non-irritant gas: molecular weight: 28.01; density:
1. 250g/l;freezing point: -207°C ; boiling point: -190°C.
Its solubility in water is quite Iow, butit dissolvesinstantly
in ammonia water. Air mixed explosion limit is between
12. 5%and 74%. Afterenteringhuman body, carbon
monoxide will combinewithhemoglobin in blood, making
the hemoglobin not able to combine with oxygen,which
causesoxygendeficit to organismorganization,leading to
death from suffocation. Therefore, carbonmonoxide is
toxic, andis colorless, odorless, and tasteless, which is
easy tobe ignoredand thuscausingpoisoning.
Gas perniciousness:carbonmonoxide can härm human
health, and seriouscarbonmonoxide would causedeath.
Therefore,people should pay attention to safe gas using,
and peopleworking in factoryshould pay attention to
carbonmonoxideconcentration.
Carbonmonoxidedetector can detectcarbonmonoxide
concentration,observingconcentration value allthe time.
It hasquite clear large LCD screen and voice and light
alarm indication, making sure that itcan detect dangerous
gas and informoperators of precautionsunderadverse
Situation. Itis widelyused in petroleum,chemistry, coal
mine, metallurgy,papermaking, fire-fighting, municipal
administration,telecommunication,food,textile and other
industries.
Carbon monoxidedetectorfunctions:
»•Large-screen digital and characterdisplay,instantvalue and
maximumvaluedisplay.
»-Safety indication:regulärlightflashing and voiceindication.
Whencarbonmonoxideconcentrationincreases,buzzing
voice frequencywouldalso be increased.
»-Excellent audible alarm.
»•Low maintenancecost.
»•Support carbonmonoxidedetection.
»•Solid shell and robust electriccharacters.
••Carbon monoxideconcentration of0-1 OOOppm canbe
displayed onthe large LCD screen.
»•Bright back-light lightening; itcan clearlyindicatecarbon
monoxidedetectorunderdarkenvironment.
»•Automatically shut offifitisnot operated for 10 minutes, to
extendbatteryservice life.
»•Convenientto replacebattery.
»-Special sensor for stableelectronicchemistrycarbon
monoxide.
»•Sensor of over three-year service life and battery of 100-
houralkalineservicelife(typical value).

US Department of Laborregulates in Article 24ofthe 1917
OSHA that:carbonmonoxideconcentration inany closed
space should benot higherthan50PPM(0.005%). If
carbon monoxideconcentrationexceeds100PPM(0.01%),
it is necessary for workers to transfertheirsites.

V. OperationInstructions
LStartup
Press the powerswitch " (l) " to start up.
2. Carbonmonoxideconcentrationvalueindication
After startup, LCD panel willdisplay inthe füll screen, and
display carbonmonoxideconcentrationvalue and
temperature valueundercurrentenvironmentaftercounting
backwards for 10 seconds.
Longpress"SCAN" to switchtemperatureunitbetween
centigrade and fahrenheit, andin casethatcarbonmonoxide
concentrationvalue is0 äs displayed onthe screen, it
indicatesthat there isno carbonmonoxideunder the current
environment.
3. Buzzing
In casethatcarbonmonoxideconcentration is between
50ppm and 100ppm,buzzing will beon discontinuously;
in casethat the carbonmonoxideconcentration is above
100ppm,buzzing will beon continuously.lt can change
buzzing alarm limit by settingmaximum and minimum
concentrationvalue.
4. Check the maximum and minimumcarbonmonoxide
concentrationvalue
Press"SET",the screen displays"HI.",and the default
maximumcarbonmonoxideconcentrationvalue is 100ppm;
press the "SET" again, the screen displays" Lo", andthe
defaultminimumcarbonmonoxideconcentrationvalue is
SOppm. Pressdown"SET", the Instrument will display the
maximum and minimumcarbonmonoxideoncentration
valuesrepeatedly.
5.Setthe maximum and minimumcarbonmonoxide
concentrationvalues
Long press the"SET",and"HI."or"Lo"will flash. Press
"SET",and the instrumentwill display"HI."or"Lo"repeatedly.
Longpress "SCAN"or powerswitch "([)" to increase or
decreasecarbonmonoxideconcentrationvalues and
increase or decreaseaction canbe rapidlyobtained by
long press the key. For example, during "Hl."flashing,
press "SCAN"for once, and 100ppmwillchange into
101ppm;presspower switch"(j)"again, and 101ppm will
changeinto100ppm, andsoon.It will automaticallyexit
the setting Status ifitisnot operated for10 seconds. Or
long press"SET"again,"HI."or"Lo"will stopflashing, andit
can alsoexit the setting Status by pressing"SCAN".
6. Maximumvalue,averagevalue and datahold
(1)Press"SCAN", andthe screenwilldisplayMAX, andat
thistime the screen will display the maximumreading.
(2)Press"SCAN"again, the screen will displayAVG, andat
this time the screenwilldisplay the averagereading.
(3)Press"SCAN"again, the screenwilldisplayHOLD, andthe
currentdatawill be locked up.
(4)Press"SCAN"again andthe screenwilldisplaySCAN.
(5)Press"SCAN",and the instrumentwilldisplay the recorded
maximumaveragevaluereading andthe currentlocked
value.
7.LCD backlight
Press the powerswitch" (|) "understarting Status, the
backlight will beon,andthe backlight will be automatically
off ifnot pressing the power switch"(l) "again for10
seconds.
8. Shutdown
Manualshutdown:pleaselongpresspowerswitch "(•)" until
"OFF"appears to shutdown.
Automatic shutdown:it is regarded äs defaultthat the machine
will automaticallyshutdown ifitisnot operated for 10
minutes.
9. Batteryreplacement
When the batterypower isnot sufficient, LCD would displays
" ^ " whichmeansthat the batterypower is not sufficient and
it is necessary to replace new battery. Ifthe instrument has
not beenused for long time,pleasetake outthe battery to
preventelectricityleakagewhich may damage the instrument.
