1.2. Main features
•Screen
Backlighted 3.5'' grey scale screen. It allows to display measured parameters in a more comfortable format for the operator.
Thanks to the zoom function (OK key), you can view on the screen the measured value in increased characters.
•Printer
The paper of the instrument is a thermal paper with a 10-year guarantee. It has an easy replacement system of the paper
(Easyload). In addition, printing is fast.
•Battery charger
The instrument is supplied 12V, 3.75A power adapter to load the internal batteries. The current loading is indicated by a
battery symbol on the top left of the screen. The red LED on the right side of the gas analyser stays on until the battery
loading is completed.
•Flue gas suction pump
The pump, inside the gas analyser, is a diaphragm pump with a motor energized in direct current directly by the instrument
in a way to get an optimal suction of flue gases.
•Flue gas probe
Probe in stainless steel with an overmoulded handle in plastic with a standard length of 15 cm (others lengths are available
as option, please see the technical datasheet for kigaz) with a fixing cone to maintain the contact tip in the duct.
•Measurement sensors
The analyser uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H2
hydrogen).
•Temperature sensors
Flue gas temperature is measured with a thermocouple integrated in the contact tip. The connection to the analyser is
made thanks to a single male connector compensated in temperature. K thermocouple (nickel-nickel chromium) allows
continuous measurements up to 1250°C.
The instrument has a NTC thermoresistance for the measurement of internal temperature ; this sensor is also used for the
measurement of ambient temperature.
If a temperature control of the combustive air must be performed directly by the supply duct (room sealed boiler), a Pt100
temperature probe (ref : SAP150P) will be used. It is recommended to perform this measurement to make the efficiency
calculation of the installation more accurately.
•Types of combustibles
The analyser is supplied with a memorization of technical data which characterize the 15 most known combustibles. It is
also possible to add 5 combustibles and their corresponding features.
•Calibration certificate
The analyser is calibrated by comparison with standard of metrology laboratories, which are periodically certified closed to
laboratories known at the international level. Each analyser is supplied with its calibration certificate in which, for every
parameters, are indicated the nominal value, the one measured, the admitted error limits and the found error.
•EMC compatibility
The analyser complies with n°2004/108/EC directive on electromagnetic compatibility. Document available on request.
•Water trap
The water trap is placed on the tube that links the flue gas probe to the Kigaz 150. The measured gases go through the
filtering element allowing the recovery of condensates (liquid one or solid one).
The filtering element is placed 15 cm from the analyser and is divided into 2 parts :
Introduction 9

–one recovers the liquid particles.
–the other contains a filter that stops the smallest particles in suspension and avoid them to reach the electro-
chemical sensors
Condensates are evacuated by opening the plug.
•CO protection
The analyser is equipped with the CO protection function that allows to avoid high concentrations of CO that could damage
the analyser and the sensors. The CO measurement is stopped when it exceeds a threshold defined by the user.
•Customers management
The analyser allows to record customers, theirs respective boilers and inspections. Once the features of customers and
boilers are completed in the analyser, the operator can easily assign the different measured values to a customer and his
boiler. These data can then printed and/or transferred to a computer thanks to Ligaz software.
•Opacity index measurement (optional)
It is possible to fill in the analyser with opacity index values measured according to the Bacharach scale. The analyser will
calculate the average and results will be printed on the ticket. This measurement must be performed with an opacity pump
which is available as an accessory (ref : PMO).
•Gas network leak testing (optional)
It is possible to check the tightness of an installation. For this control, use the pressure sensor used for the draft
measurement of the shaft.
•Measured values
–O2 : percentage of oxygen in flue gases
–CO : concentration of CO in flue gases
–Tf : flue gases temperature
–Ta : combustive air temperature
•Calculated values :
–λ : Air Excess : connection between the volume of combustive air and the requested volume necessary for a
combustion in stoichiometric conditions.
–CO2 : percentage of carbon dioxide in flue gases
–ΔT : difference between the flue gases temperature and the combustive air temperature
–Qs : percentage of waste heat throughout the shaft
–ηs : Lower efficiency (or sensible) : this the burner efficiency calculated according to the EN50379 standard
disposals. This is a ratio between the conventional heating power end the burner heating power. Among the
combustion losses, only the sensible heat lost with the flue gases is taken into account, neglecting the radiation
losses and incomplete combustion losses. This value is referred to LHV (Lower Heating Value) and can not be
higher than 100%.
The sensible efficiency value is to be compared with the minimum efficiency stated for the heating systems
performances.
–ηt : Higher efficiency (or total) : is the sum of sensible efficiency and the additional efficiency deriving from
the recovery of water vapour condensation contained in the flue gases. When it s greater than sensible
efficiency, then condensation is taking place. It is referred to LHV (Lower Heating Value) and can exceed
100%. The LHV is calculated by an algorithm developed by Kimo and its value must be considered as
