QMI 1000
Overview
The
QMI 1000
Combustion Analyser measures carbon dioxide (CO
2
)
,
carbon
monoxide (CO), differential temperature and differential pressure. The direct
measurement of CO
2
is achieved using a
n
infra-red sensing system.
CO
2
is set to zero in fresh air automatically after the initial countdown.
If “RESET CO2 ZERO” is indicated ensure that the unit is in fresh air before
pressing the button with an “Enter” symbol.
It calculates oxygen (O
2
), CO/CO
2
ratio, losses, combustion efficiency (Nett,
Gross or Condensing) & excess air.
The
QMI 1000
Combustion Analyser can also measure CO levels in ambient air
- useful when a CO Alarm is triggered. It can also perform a 15 minute duration
Room CO Test
for BS7967
.
The analyser has a protective rubber cover with a magnet for “hands–free”
operation and is supplied with a flue probe with integral temperature sensor.
The large display shows 4 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:
99 combustion tests
20 pressure tests
20 let-by/tightness tests
20 temperature tests
20 room CO tests
Two lines of 20 characters can be added to the header of printouts.
The analyser is controlled using 4 function buttons and a rotary dial.
The four buttons (from left to right) switch on and off the analyser, switch on
and off the backlight and task light, 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.
