1. Introduction
1.1. Description of the gas analyser
The KIGAZ 110 is a gas analyser with two interchangeable sensors (long-life O2 and CO-H2).
Its main features are the following:
•Sensors protection by pump stopping and configurable thresholds
•ustomers management
•reation and edition of inspections with the integrated printer
•15 programmed combustibles and possibility to add up to 5 combustibles
•2 GO of memory
The gas analyser is supplied in a transport case with a magnetic protective cover, a flue gas probe and its water trap, a
Li-Ion battery and its charger, LIGAZ-2 software which allows inspection creation, an USB cable and a calibration certificate.
This analyser is designed to control parameters of flue gas in e haust duct or heating units. It can not be used in a
permanently way and/or used as an alarm system.

1.2. Main features
•Screen
L D screen, 120 x 160 pixels, 50 x 67 mm. It allows to display the measured parameters in a comfortable format for the user. With the
zoom function, the measured values can be visualised in increased characters.
•Printer
The printer has 10-year guarantee thermal paper. Printer has an easy replacement system of the paper (Easyload). In addition, printing
is fast.
•Batteries charger
The instrument is supplied with a 6 V, 1.5 A 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.
The battery charging time is 10 hours. The voltage of power supply is 100-240 VA , 50/60 Hz. The number of cycles of the battery is
about 500 charging cycles.
•Flue gas suction pump
The pump, inside the gas analyser, is a diaphragm pump with a motor. It is 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 over-moulded handle in plastic, with a standard length of 18 cm with a fixing cone to maintain the
contact tip in the duct. Interchangeable, it is connected to the instrument by a neoprene tube of 2.50 m.
•Measurement sensors
The analyser uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H2 hydrogen).
Recharge regularly the battery to guarantee an optimal operating of the electrochemical sensors.
•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 NT 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: SPA 150 SP) will be used. It is recommended to perform this measurement to make the efficiency calculation of the
installation more accurately.
•Supply input of flue gases and +/- pressure
The analyser has a single connector which allows to plug the flue gas probe.
•Types of combustibles
The analyser is supplied with a memorization of technical data which characterizes 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.
•Conformity and standards
The analyser complies with n°2004/108/E directive on electromagnetic compatibility. Document available on request. It
also complies with 2006/95/E Low Voltage, 2011/65/EU RoHS II and 2012/19/WEE directives.
Moreover, the analyser complies with EN 50379-1 and 50379-2 standards.
•Water trap
The water trap is placed on the tube that links the flue gas probe to the KIGAZ 110. The measured gases go through the filtering
element allowing the recovery of condensates (liquid 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.
ondensates are evacuated by opening the plug.
The presence of a water trap with filter can cause some gases solubility in water during gas analysis.
•Auto-zero
The analyser has the “auto-zero in the duct” function, it means that the operator can perform measurements (draft, temperature...)
while the analyser inhales fresh air in the room. This function allows to save time on the inspection l.
•CO protection
The analyser is equipped with the O protection function that allows to avoid high concentrations of O that could damage the
analyser and the sensors. The suction-pump is stopped when it exceeds a threshold defined by the user. It is also possible to press the
Kigaz OK key to activate the protection during a gas analysis.
•Customers, boilers and inspections 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.
•Opacity inde 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 differential pressure
measurement of the shaft (ref. KEG).
•Measured values
- O2: percentage of oxygen in flue gases
- CO: concentration of O in flue gases
- Tf: flue gases temperature
- Ta: combustive air temperature
•Calculated values
- λ: Air E cess : 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 chimney.
- ηs: Lower efficiency (or sensible): calculated burner efficiency. This is a ratio between the conventional heating power
and 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 indicative.
- CO (O2): oncentration of O in flue gases in mg/m3. It is calculated according to O2 reference value indicated in the
analyser (see page 19).
