1.2. Main features
•
Screen
Backlighted TFT 3.5'' color screen. It allows to display measured parameters in a more comfortable format for the operator. Thanks to the zoom
function, you can view on the screen the measured values 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 with a 12 V, 3.75 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.
•
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 flues gases. The pump is regulated by a continuous measurement of the output flow by the pressure sensor n°3.
•
Flue gas probe
Probe in stainless steel with an overmoulded handle in plastic, with a standard length of 30 cm and with a fixing cone to maintain the contact tip in
the duct. Interchangeable, it has a LED allowing to light the dark areas. The probe is connected to the instrument by a neoprene tube of 2.50 m.
The handle is also equipped with a filter that keeps the solid particles of flue gases during the combustion analysis.
•
Interchangeable measurement sensors
The analyser uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H
2
hydrogen). Measurement sensors
are interchangeable.
•
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.
•
Pressure sensors
The analyser has 3 piezoelectric internal sensors for the measurement :
1 – of the differential pressure (Delta P) with manual autozero
2 – of the high accuracy draft with autozero by solenoid valve
3 – of the pump output flow with a regulation which allows to compensate a clogging of the filter or a high draft. This sensor allows to perform the
tightness test of the analyser.
•
Supply input of flue gases and +/- pressure
The analyser has a single connector allowing the connection of flue gas probe.
•
Combustibles types
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 integrated to the Kigaz 300. Measured gases go through the probe filter then through the water trap which recovers the liquid
element and, as a result, protects the sensors.
Condensates are evacuated by the opening of the plug located on the bottom on the instrument.
When the maximum level is reached, a red led lights and the pump stops. It allows to warn the user when the water trap must be emptied.
