Atmospheric analysis sensor

The University of Edinburgh Field Spectroscopy Facility requires a sensor with the capability to measure NO2, CO2 and CH4 concentrations at altitude/height simultaneously and in real time, at a detection limit in the <1 ppb for methane, <0.5 ppb for NO¬2 and < 200 ppb for CO¬2. The concentrations are required for flux measurements, and therefore the temporal frequency of measurements is important, measurement frequency needs to be no less than 1 Hz, ideally at 5 Hz. To enable use of the facility’s existing UAV equipment the sensor must be able to interface with a DJI M400 drone, and the total sensor weight must be under 7kg. After a market evaluation it is believed there is only one solution which can fulfil the combined requirements – the Aeris Sensors MIRA Strato. As such we intend to award via the Negotiated Procedure Without Prior Call for Competition, to their sole EU distributor, on the basis competition is absent for technical reasons. Any suppliers who wish to query or challenge this notice should do so within 10 calendar days of its publication. Value represents cost excluding VAT and import duties (if applicable).
