Maintenance
To ensure that the EASIRTM-4 Thermal Camera is kept in good working condition and remains fully operational, the
following guidelines should be adhered to at all times.
Non-optical surfaces
The non-optical surfaces of the camera can be cleaned when required, with a soft cloth dampened with water and a
mild detergent.
Calibration and Repair Philosophy
To ensure the accuracy and reliability of the EASIRTM-4 Thermal Camera, it is highly recommended that the instrument
be calibrated at 12 monthly intervals.
Optical surfaces
The lens of an IR camera is very expensive. Replacement or repair may be thousands of dollars. The anti-reflective
coating on the surface of the lens is the most expensive part of the lens assembly (and is also critical to the radiometric
capabilities of the system).
The optical surface should only be cleaned when visibly dirty. Care should be taken to avoid oil, chemical dirt and
touching the exposed lens surface, as skin acid left behind from fingerprints can be damaging to coatings and lens
substrates. After using the imager, please close the lens cover.
Do not use dilution to clean the imager and its accessories, especially the optics. Use clean soft dry tissue to clean the
imager body, and the supplied lens cleaning tissue for lens.
Calibration or repair for the instrument can be obtained by either contacting the address/ telephone number on the
