Calibration Services

Accu provides calibration services that help businesses maintain accuracy, reliability and documented measurement confidence. Our service range covers dimensional, electrical and environmental instruments with collection options across South Africa.

Calibration Services

Calibration Services For Daily Production And Audits

Accurate measurements keep production moving, reduce rework and help teams pass internal checks, customer inspections and compliance reviews. Accu calibrates instruments used in workshop, laboratory and field environments, with services arranged for businesses in Johannesburg, Gauteng and nationwide through courier collection. We work with equipment that is used every day and needs confidence behind every reading, not just a once off check.

Our calibration services suit manufacturers, engineering teams, maintenance departments and technicians who need measurements they can trust. Whether the equipment is used on a packing line, in a machine shop, or during site inspections, we help keep it within expected limits and properly documented.

  • Dimensional instruments for length, diameter and alignment checks
  • Electrical instruments for testing and troubleshooting work
  • Environmental instruments for temperature and humidity monitoring
  • Torque, force and pressure tools used in production and maintenance

How To Choose The Right Calibration Service

The right calibration depends on what the instrument measures, how often it is used and how critical the reading is to your process. A caliper used on a fabrication bench has different needs to a pressure gauge on a plant line, and a humidity metre in a storage area needs different attention again. If your instruments are used in dusty plants, coastal humidity or areas with frequent temperature swings, regular inspection and cleaning routines are even more important.

We help clients decide what should be calibrated, how often it should be checked and what records should be kept for traceability. If you are unsure, send through the instrument details and application so we can advise on the most practical route.

  • High use tools usually need more frequent calibration
  • Critical measurements call for tighter tolerance control
  • Environmental conditions can affect instrument stability
  • Audit requirements may call for certificates and traceable records

Dimensional Calibration For Workshop Accuracy

Dimensional measuring tools are central to machining, assembly and quality control. We calibrate calipers, micrometers, gauges, indicators and height gauges used by workshops and production teams across Isando, Kempton Park, Edenvale, Germiston, Boksburg, Jet Park, Meadowdale and Midrand. These instruments often move between benches, storerooms and site work, so even careful handling can lead to drift over time.

Our process is suited to businesses that need dependable results for parts inspection, setup work and batch control. Small measurement errors can create scrapped parts or fitment issues, so it pays to keep these tools within spec and properly recorded.

  • Caliper calibration for outside, inside and depth readings
  • Micrometer calibration for precise small-range measurements
  • Gauge and indicator calibration for setup and inspection tasks
  • Height gauge calibration for bench and inspection table use

Electrical And Process Instrument Calibration

Electrical and process instruments need stable performance because a weak or drifting reading can lead to faulty diagnosis, downtime or unsafe decisions. We calibrate multimeters and other electrical measuring tools used by technicians, maintenance teams and commissioning crews. We also support torque tools, force gauges and pressure gauges used in assembly, plant maintenance and process control.

For many clients the key issue is not just accuracy, but having a record that shows the instrument was checked by a specialist lab. That matters for quality systems, supplier requirements and customer audits. It also helps when tools are shared between departments or used on multiple sites.

  • Multimeter calibration for electrical testing
  • Torque tool calibration for fastening and assembly control
  • Force gauge calibration for load and pull testing
  • Pressure gauge calibration for plant and field equipment

Temperature And Humidity Checks For Sensitive Areas

Temperature and humidity readings matter in storage rooms, production areas, cold rooms and controlled environments. Fluctuations caused by weather, aircon changes or power interruptions can affect equipment performance and stored product conditions, especially in coastal humidity or hot summer conditions. If your process depends on stable environmental readings, regular calibration supports better control and fewer surprises.

Accu calibrates environmental instruments used for monitoring and verification in warehouses, labs and manufacturing areas. We keep the process practical, with clear communication and a turnaround that works for operational teams who cannot afford long delays.

  • Temperature calibration for probes, metres and monitoring tools
  • Humidity calibration for storage and environmental checks
  • Suitable for site use, laboratories and controlled rooms
  • Useful for compliance records and routine verification

Courier Collection And Lab Support Across South Africa

Our calibration lab is based in Isando, Kempton Park, and we offer courier collection nationwide for businesses that cannot drop off instruments themselves. This helps clients in Johannesburg, Pretoria, Durban, Cape Town and regional industrial areas get equipment to us without disrupting operations. If you manage multiple branches, we can help organise collections in a way that keeps the process simple and traceable.

Once the equipment reaches our lab, it is checked, calibrated and returned with the supporting documentation your team needs. Clients contact us through the enquiry form on the contact page and our team then advises on the best collection route, expected timing and the instruments that should be sent together. It saves time and avoids the back and forth that often slows down internal maintenance plans.

  • Courier collection for single instruments or bulk batches
  • Support for branch networks and national operations
  • Ideal for planned shutdowns and maintenance windows
  • Documented return for record keeping and audits

Questions we get asked

Which instruments can Accu calibrate?

We calibrate dimensional, electrical and environmental instruments including calipers, micrometers, gauges, indicators, height gauges, torque tools, force gauges, pressure gauges, temperature instruments, humidity instruments and multimeters.

Do you offer collection outside Johannesburg?

Yes. Accu offers courier collection nationwide, so businesses outside Isando and Kempton Park can send instruments to our calibration lab without arranging their own transport.

How do I request calibration services?

Use the enquiry form on our contact page and include the instrument type, quantity and where it will be collected from. Our team will respond with the next steps and collection arrangement.
