Working principle
The Si-CA 320 is a portable analyser for combustion and emissions analysis.
The device is equipped with:
•
A pneumatic circuit that can contain up to 6 sensors
•
An intuitive user interface allowing the device to be used without the operating instructions
•
A wide (55 x 95 mm) and bright TFT colour display providing good legibility thanks to its zoom function and efficient backlighting
•
A rechargeable Li-Ion battery pack
•
Ticket printing via an external Bluetooth
®
printer (available as an option)
•
Ability to generate QR codes to download the analysis/measurements displayed on the screen. The "Si-CA QRCodeApp" application,
available in the Google and Apple stores, must first be installed.
•
Ability to connect to a PC via USB or Bluetooth
®
connection. Once the software provided with the device is in use, combustion analyses
and the configuration of the main parameters can be stored.
•
Ability to connect with a smartphone via Bluetooth
®
. Once the "Si-CA MobileApp" application, available in Google Play, is installed, it is
possible to perform remote analyses and/or view the current analysis in real time.
Main functions:
•
Flue gas analysis in manual or automatic mode. The 15 most commonly used fuels are integrated with the option to add 32 (once their
chemical composition is known).
•
Pollutant monitoring
•
Memory space for up to 2000 complete analyses
•
Storage of acquired data and an average of it

Measurements:
•
Ambient CO (via an internal sensor)
•
Drawing in the duct
•
Smoke (with an external manual pump)
•
Gas pressure in the pipes, pressure in the combustion chamber and verification of pressure switches using a measuring range up to
200 hPa
•
Measurement of combustion air
•
Auxiliary temperatures
•
Tightness test
•
Velocity of air or smoke leaving the duct with a Pitot tube
•
Measurement of ionisation current (using external probe)
Maintenance:
•
The sensors can be replaced by the user without having to send the instrument back to the after-sales service because the sensors are
delivered pre-calibrated.
•
Calibration certification:
the instrument is delivered with a calibration certificate. As an option, it is possible to obtain a calibration
certificate issued in accordance with the requirements of EN17025.
