Our services could be organized on three main activities, described as follows:


Our main services include:

  • Naval repairings
  • Maintenance
  • Installations (electrical, hydraulic, pneumatic)
  • Calibrations
  • Automation
  • Generators and motors overhauling
  • MMEE maintenance and control
  • Control panels and consoles
  • Electrical heat tracing
  • Optic fibre
  • Fire Fighting systems
  • Pneumatic gates
  • Process tubing
  • Tanks levels
  • Draft


Between different measure variables that can be calibrated at our laboratory (that also could be externalized for in-situ calibrations) are the following:

  • Pressure (0 – 690 bars)
    • Pressure gauges
    • Vacuum gauges
    • Pressure relief valves
  • Temperature (0 –350 ºC)
    • Termometers
    • Temperature calibrators
  • Electrical variables
    • Amperes (0 – 550A)
    • Voltage (0 – 1000v)
    • Electrical resistance (W)
    • Electrical Isolation (MW)
    • Electrical capacity (F)
    • Frequence (Hz)
    • Thickness measures
    • Torsion meters
    • Luminous intensity
    • Flow
    • Velocity (tachometers)

All these calibrations are carried out together with their corresponding certificate emission.

Is our next aim, in short time, to certificate our laboratory by ENAC (National Accreditation Entity).
