Electrical maintenance

Maintenance of switch cabinets with thermal imager

In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect.

  • Evaluation of the heat status of low, medium and high-voltage systems by the help of thermal imagers
  • Early detection of defective components or connections
  • Minimize dangerous fire risks and prevent costly production downtimes

Electrical measurement parameters


Testing plants with the user-friendly electrical measuring instruments from Testo: innovative technology and easy handling ensure precise and reliable measurement of electrical parameters such as current, voltage or resistance.

  • Multimeter
  • Clamp meter
  • Current tester
  • Voltage tester

Mechanical Maintenance

Mechanical maintenance industry

Signs of wear in machinery often become apparent long before a malfunction, due to an increase in temperature.

  • With a thermal imager, any suspicious changes can be spotted immediately
  • Your maintenance operation can be carried out on all mechanical installations during operation and from a safe distance
  • Non-contact fill level check and safe high temperature measurement
