QTC are able to provide a wide range of dimensional equipment calibration service with the issue of either a HKAS endorsed certificate or a standard traceable certificate.
The following list illustrates some examples of equipment:

  • Calipers
  • Micrometers (external)
  • Steel rules
  • Measuring tapes
  • Height gauge*
  • Dial gauges
  • Digimatic gauges
  • Linear Variable Differential Transducer (LVDT)
  • Extensometers
  • Depth gauges*
  • Feeler gauges
  • Coating thickness gauges
  • Calibration foils
  • Engineers squares
  • Straight edges
  • Angle meters*
  • Protractors*
  • Spirit levels
  • Tachometer

*Non-HOKLAS item.

Temperature

Thermometers (LIG, dial/analogue, electronic/digital, recorder/logger and thermocouple)
The calibration is performed in a well environmental controlled laboratory with a variety of liquid baths and dry blocks all of which provide stable isothermal environments for the temperature calibration of thermometers, thermocouples and temperature recorders using comparative techniques.

QTC can provide temperature calibration and issue either a HKAS endorsed certificate or a standard traceable certificate over the range from (-40 to 320)°C.

Mass Calibration

Balance

QTC provides the calibration of balance up to 60 kg capacity using Class E2/F1 standard weights. In addition to offering this service in our permanent calibration laboratory, we also offer an on-site balance calibration service. Both the calibration services carrying out in QTC permanent laboratory or on-site are both HOKLAS accredited.

Weight

Check weights should be used for the intermediate-check of the balance performance between full calibrations. QTC can provide the calibration service for weights with standard values from 1 mg to 50 kg and non-standard values from 1 mg to 60 kg by comparing to Class F1 standard weights and issue a HKAS endorsed certificate.

Force Calibration

Force machine

QTC provides on-site calibration service for material testing machines (e.g. compression testing machine, universal testing machine, static uniaxial testing machine) for the force range from 3000 kN down to 0.2 kN. We are HOKLAS accredited to carry out the load verification as well as the strained gauged column and proving test (stability test).

Load measuring device

(e.g. Load cell, pull-off tester, hydraulic jack*)
QTC provides calibration service for load measuring devices within the force range from 2000 kN down to 0.2 kN in compression mode and issue either a HKAS endorsed certificate or a standard traceable certificate.
*Hydraulic jack calibration is non-HOKLAS item.

  • Other material testing machines.
  • Impact testing machines to ISO148.
  • Hardness testing machines to ISO6507.

  • Slump cone and tamping rod
  • Flow table, mould and tamping bar
  • Slump flow base plate
  • Test sieves*
  • Weld gauges
  • Calibration blocks (e.g. A2, A4, DAC)*

*Non-HOKLAS item.
A HKAS endorsed certificate or a standard traceable certificate will be issued after a successful calibration.
