MADUR Electronics' GA-12 pocket-sized analyser includes two or three gas sensors (O2, CO, CO2, Nox), gas/air temperature measurements, pressure and differential pressure measurements with 0.1Pa resolution, and optional rH measurements.
Available from Anri Instruments , the GA-12 also includes the option of gas flow velocity measurements.
The large, easy to read LCD screen can show the current values or the menu for choosing the various parameters such as fuel type, averaging period, etc.
The results screen shows all relevant data concerning gas temperature and concentration, combustion efficiency and the values of the analogue inputs (V, mA, and ºC).
Weighing only 600g (without probe), the GA-12 has extremely long battery life (up to 72 hours), real-time clock/calendar, and easily upgradeable flash program memory.
The GA-12 has non-volatile memory for 32 reports ('measure now, print later'), and includes IR communication for external printer (HP 82240B). Optional RS232C interface for connection to a PC and multifunctional PC program are also available.
The unit performs a zero calibration immediately after being switched on, and its simple, easy to use, 'mobile phone' style operation makes the GA-12 a convenient device.
