Process Instrument Calibration & Maintenance Services


Instrument Calibration Specialists

Douglas Calibration Services has been providing on-site calibration services to companies throughout Ireland since 1991 and has built a reputation of delivering outstanding customer service.

We also provide a Commissioning service for your new facility, or provide experienced Professionals to supplement your Calibration Maintenance & Commissioning Departments.

Using our comprehensive range of certified test equipment, our technicians will visit your plant and calibrate your instruments in accordance with the calibration programme set out. Calibrations are carried out using our standard operating work instructions unless required to follow specific site procedures.

At Douglas Calibration Services, we want to ensure that your process measuring equipment is calibrated, and meets the required tolerance, which is why customers are choosing to use DCS for their on-site calibration. Further, they know we consistently maintain ISO certifications for quality assurance and train our technicians so that they are competent and always kept apprised of the latest technology.

When it comes to on-site calibration, we also offer:

  • Flexible scheduling for your on-site calibrations
  • Competitive rates
  • Rapid response to any call-out requirements
Our expertise will ensure you that once we leave the plant, you already have a copy of the calibration reports in-hand and the process is back up and running to optimal performance. This will provide you with the peace of mind knowing that we are committed to you achieving superior manufacturing quality by providing superior on-site calibration service.
