NIR Thermal Imager Installation Guide
3 Installing the Thermal Imager
If the thermal imager is to be used in conjunction with a protection jacket and
air purge, refer to the installation guides provided with those accessories.
If the thermal imager is to be installed in a location where the ambient
temperature is within the ranges specified for the thermal imager, and no
air purging is required to keep the lens clean, the thermal imager can be
mounted using the two tapped holes on the mounting pad. Either hole can be
used for direct tripod mounting.
A swivel ball mounting (S4 - B) is available from Land infrared. This
mounting accessory enables you to easily adjust the thermal imager's line of
sight.
