Conveyor belt monitoring system to automatically monitor scaffold planks and poles for Alpha Beta or Gamma contamination
This conveyor belt monitoring system is designed to provide automatic monitoring of beta/gamma or optionally alpha/beta/gamma contamination on scaffold planks or poles. The system consists of a mobile central unit containing the conveyor belt drive system and measuring electronics and separate mobile loading and unloading take-up tables with rollers.
The Scaffold Monitor provides a reliable, consistent method of monitoring large area surfaces over a large number of samples not practical with hand held probes.
