1.2. Main features
•
Screen
LCD 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. The 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 VAC, 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 a handle in ABS and a standard length of 30 cm (other probes are available as option, see the technical
datasheet of accessories for KIGAZ), with a fixing cone to maintain the contact tip in the duct. Interchangeable, its LED allows to light
dark areas. It is connected to the instrument with a neoprene tube of 2.50 m.
•
Interchangeable measurements sensors
The analyser uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H
2
hydrogen). The
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: SPA 150 SP) will be used. It is recommended to perform this measurement to make the efficiency calculation of the
installation more accurately.
•
Pressure sensor
The analyser has one internal piezoelectric sensor for the measurement of the differential pressure (Delta P) with manual autozero.
•
Supply input of flue gases and +/- pressure
The analyser has a single connector allowing the connection of a flue gas probe.
•
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.
•
Conformity
The analyser complies with the EN 50739-1 and 2 standard.
