Aeris MIRA Ultra N2O/CO

The instrument is housed in a ruggedised case with an in-built battery that can power the instrument for up to 3 hours in the field. The live data can be accessed using a tablet which connects to the analysers Wi-Fi using VPN. The analyser also comes in with an inbuilt GPS module to enable accurate position data for the observations.

The instrument can be calibrated using compressed gas mixtures produced at the AMOF Cylinder Filling Facility (CFF) based at the University of East Anglia. The N2O and CO amount fractions in these cylinders has been determined by the CFF.

Consumables

The user will need to supply (otherwise will be charged for):

• Teflon filters 

Costs

Instrument Insurance

This system must be insured by the user for £45K and covers loss, theft or damage to the instrument: damage is that over and above general wear and tear. The system has been designed to be rugged and autonomous. Even so, the end-user must respect the fact that the system is a precision optical instrument that must be treated with great care.

The user is responsible for the instrument from the time it leaves the AMOF to the time it is returned and signed off as in an acceptable operating condition by the IS: this will be done as soon as is possible on its return.

Public Liability Insurance

The AMOF is not liable for any damage or injury arising from the deployment or operation of this instrument when unattended by the IS.

Shipping Expenses

The user is liable for all costs arising from the shipping of the instrument both to and from a deployment.

IS T&S

The user is responsible for coving the travel and subsistence expenses of the IS while attending the instrument.

Shipping

The system when packed ready for shipping consists of a single case:

• Shipping dimensions (in case):

74 cm x 50.7 cm x 78 cm (91 cm with castors)

Shipping weight (in case): tbd

Although the analyser has active temperature control, operation in an air-conditioned laboratory will improve performance It is advisable to use the shortest inlet line possible with a large flow rate to limit residence times.

Manual handling

For the safest operation, leave the analyser in the shipping case during operation.

If needed,

• A procedure appropriate to lifting a heavy object should be used when lifting the analyzer. This procedure consists of bending at the knees while keeping your back straight and upright.
• The analyzer should be grasped at the bottom, in the front and at the rear of the unit.
• Do not attempt to lift the analyzer by the cover or other external fittings.
• While one person may lift the unit, it is desirable to have two persons lifting,
• one by grasping the bottom in the front and the other by grasping the bottom in the rear.
• Cables and sample tubing kept away from pathways; held overhead height if necessary.
• Walkways kept free of clutter and access to exit kept clear.
