Our core discipline

Calibration Services

Our calibration laboratory is accredited to ISO/IEC 17025:2017 and listed as active on the NiNAS register. We calibrate in our laboratory or on your site, and issue traceable certificates that hold up to audit.

Calibration is the discipline the company was built around. Over 15 years of cumulative experience in metrology, instrumentation and control sits behind every certificate, and the supporting technical team handles installation, repair and after-sales service on the same instruments.

Instruments we calibrate

  • Pressure and vacuum instrumentation
  • Temperature instruments, probes, baths and dry blocks
  • Electrical test and measurement equipment
  • Flow, level and analytical instruments
  • Process and control instrumentation

How we work

  • Laboratory calibration at our Ikosi Ketu facility
  • On-site calibration where the instrument cannot be moved
  • Calibration scheduling and due-date reminders
  • Certificates issued under our accredited scope
  • Traceability aligned to ISA and NIST
