Controls and guide tubes
Compatible with standard (660 type) remote controls and source guide tubes.
Inspection requirements
Daily pre-operational inspection for obvious damage to the system.
Maintenance requirements
Most national regulations require inspection and maintenance of the system at quarterly
intervals. The complete annual servicing ensures the integrity of the system.
Shorter frequencies of inspection and maintenance are required when the system is operated
under severe operating environments. In some cases, the system should be serviced immediately
after certain jobs in severe environmental working conditions.
Operating temperature range
-40°F to 300°F (-40°C to 149°C).
