diverse, especially operational considerations

Operational restriction

several, both in terms of accuracy (e.g. the necessity to avoid diffusion of high ambient VOC concentrations), and in terms of safety (FID with H2). The use in the ventilated underwing pods of MetAir's DIMO is well tested since 1994, but, a use in a cabin might need a box with protective gas, and might be a challenge for certification

Operational requirements

240 VAC, 70 Watts, RS-232 with different non-standard handshake (best with original DOS-based program)

Certification approvals

only for the well-ventilated underwing-pods of the DIMO, permanently watched by the operator (real-time display in the cockpit).

Additional information

Needs a preparation phase of at least 2 weeks before any campaign.
