Amstel CP overview

For protection of pipelines in mild climate environments the Amstel is the best chose for the following reasons:

  • Save on cost made to locally measuring the TR information. With the Amstel series it's very cost effective to have remote control and monitoring with GSM unit.
  • Only adjustable for authorized people.
  • Very accurate.
  • Timer control with the GSM unit.
  • Easy to integrate into a pipeline management system.
