The Microx module will provide reliable and fault free service when given
regular maintenance and calibrations.
5.1
Routine Inspection and Maintenance
It is advisable to periodically inspect the Microx module installation:
Clean gas detector head using a clean DAMP cloth.
Inspect the sensor and ensure it is sound and the sensor-housing
aperture is not obstructed (where applicable).
The maximum time interval between routine inspections and should be
assessed by the calibrating personnel and will depend upon the environment
in which the equipment is installed.
Calibration requirements and periods vary depending on sensor type and
application. A reasonable schedule should be arrived at by the user.
Sensors utilising Zirconia Technology
These are very stable over their normal lifespan and usually do not require
regular calibrations. A check on calibration can be made at intervals to suit the
application by the user and if a calibration operation is deemed necessary,
follow the instructions contained in this manual.
Avoid exposing the Sensor to moisture or wetting particularly if the gas being
presented for measurement by the sensor contains condensable vapours or
entraned liquids. Pre-filtering and drying of the gas to be sampled may be
required by the user.
If the Sensor is not powered for any period, then condensable moisture must
be prevented from entering the sample system and reaching the sensing
element.
Other gases to avoid are halogens, organic vapours, H2S and SO4.
