The C165 has a dilution pump which helps to protect the CO sensor from high concentration that otherwise might damage the sensor and is designed
specifically for higher altitude applications and use .
The C165 Combustion Analyzer measures carbon dioxide (CO
2
), carbon monoxide (CO), differential temperature and differential pressure . The direct
measurement of CO
2
is achieved using an infrared sensing system . Below 1% CO
2
the readings of CO
2
are displayed to two decimal places .
CO
2
is set to zero in fresh air automatically after the initial countdown . The countdown varies between 90 and 60 seconds dependent on ambient
temperature .
If “RESET GAS ZERO” is indicated ensure that the unit is in outside fresh air before pressing the button with an “Enter” symbol .
It is important that re-zeroing is done in outside fresh air as indoor CO
2
levels are affected by human breath .
It calculates oxygen (O
2
), CO/CO
2
ratio, losses, combustion efficiency (Gross, Gross Condensing, Net or Net Condensing) .
The C165 Combustion Analyzer can also measure CO levels in ambient air - useful when a CO Alarm is triggered . It can also perform a Room CO Test
for up to 30 minutes duration .
A structured Commissioning Test has been included for the installation of boilers .
The analyzer has a protective rubber cover with a magnet for “hands–free” operation and is supplied with a flue probe with integral temperature
sensor .
A low flow detection system warns of low flow and switches the pump off . This also helps to prevent water ingress from overfilled water traps .
Its LCD display is protected with a toughened screen .
The large display shows 6 readings at a time and all data can be printed via an optional infrared printer . The printed data can be 'live' data or ‘stored’
data .
The memory can store up to:
60 combustion tests
20 AUX tests
20 heat exchange tests
20 temperature & pressure tests
20 room CO tests
20 commissioning Tests
Two lines of 20 characters can be added to the header of printouts . Printouts can be made on the optional UEi printers with ‘fast print’ capability .
Alternatively, the analyzer can be equipped with optional wireless communications to either Android
™
or Apple
®
devices .
The analyzer is controlled using 4 function buttons and a rotary dial .
The four buttons (from left to right) switch on and off the analyzer, switch on and off the worklight, switch on and off the pump and send data to a
printer or to the memory . The buttons with “UP”, “DOWN” and “ENTER” arrows also change settings such as date, time, fuel, etc . when in “MENU”
mode .
