Calibration

Pressure Calibration

We at VEETECH perform pressure calibration up to 35,000 PSI. Our services include barometer calibration, manometer, pressure transducer calibration, dead weight tester and pressure gauge calibration.

With every pressure calibration you receive a Calibration Certificate from us with all the information you need about the condition of your instrument, calibration results, traceability, our accreditation to ISO/IEC 17025, and repairs and adjustments made.

The Pressure Calibration Process

Pressure modules with capacities from vacuum to 35,000 PSI are used to perform pressure calibration and record the readings. It is customary to exercise the instrument to its full capacity three times before beginning calibration. As with most calibrations, a standard with a known value or capacity is compared to the instrument being calibrated during the pressure calibration process.

Dimensional Calibration

We have leading, full-service calibration lab with the credentials and services to assure your measuring hand tools and instruments measure precisely and efficiently. Our dimensional calibration services include tool calibration for a variety of measuring hand tools, from calipers and stop watches to angle plates an, as well as micrometer calibration, gauge calibration, and calibration of masters and standards.

The Dimensional Calibration Process

Dimensional calibration is done by comparing the performance output of a hand tool, gauge or another measuring instrument with a measurement standard to confirm that the device produces results which either meet or exceed that standard’s criteria. The details of these results are clearly reported on your Calibration Certificate.

Temperature Calibration

We at VeeTECH have capabilities  available for most temperature-reading instruments including recorder, hygrometer, RTD probe, pyrometer and thermocouple calibration. Thermometer calibration for digital, infra-red, bimetal, surface and liquid in glass models is also provided. Our technicians survey temperatures at various locations in the oven or furnace to accurately identify the need for adjustments that will maintain consistent temperature throughout. We work with top-of-the-line calibration equipment to verify optimal performance from your temperature instruments.

Our field technicians can calibrate ovens, furnaces, temperature controllers and other instruments right at your facility, and you can count on a reasonable turnaround with every order.

The Temperature Calibration Process

We utilise a number of different processes to perform temperature calibration on a wide range of instruments both in our lab and on the field. Digital recorder and thermometer calibration takes place on High Precision Oil bath and Dry Blocks.

Torque Calibration

Torque wrench calibration, screwdriver (preset) and torque sensor calibration makes use of a torque system with the option to select the appropriate transducer for the range of the instrument from among multiple choices. Torque multipliers are also calibrated with transducers, but require the use of two transducers. One transducer measures the generated torque input, while the other measures the torque output.

Mass Calibration

We at Veetech provide a range of mass calibration services including balance calibration, scale calibration, weight calibration and comparator calibration at our climate-controlled facility. Some instruments can also be calibrated on-site at our customers’ facilities by our specially trained field technicians.

Our calibration standards are traceable to national standards and mass calibration is accredited by DAC (Dubai Accreditation Centre). Weight calibration is available for a wide range of classes, including E1,E1,F1,F2,M1 and M2. Our lab has equipment capable of performing balance calibration, scale calibration and comparator calibration on test items with capacities over 1,000 lbs.

You will receive timely, accurate results and an easy-to-read Calibration Certificate with a full report of all work and results.

The Mass Calibration Process

GCLC is equipped with a number of scales designed to handle mass calibration of standards and instruments at various weights and accuracies. The calibration entails a weight comparison from the scale readout against a known standard or mass value. The precision mass standards used for calibration are of a known accuracy.

Calibration Capabilities

Force Calibration

Instruments such as Tension meters, force gauges and load cells are dependent on accurate force calibration in order to consistently deliver their specified performance..

All results from our force calibration service will be clearly detailed in a Calibration Certificate.

The Force Calibration Process

Force calibration is performed in one of two ways at our laboratory depending on the weight capacity of the equipment being tested. Most often, equipment with a capacity below 500 LBF will be calibrated using a hand-held dead weight test for tension and compression. Instruments over this weight capacity are generally tested on a  force calibration machine with a capacity of 3000kN.

The first step is exercising the customer’s equipment to be sure it is in working order for the process to follow. Next, the appropriate equipment is selected and the standard is set. A 5-point calibration will be run for most instruments at every 20 percent of capacity, although a higher accuracy instrument will require 10 points at 10 percent of capacity.

Calibration Capabilities

  • Tension Meter
  • Force Gauge Calibration
    • Tension, Compression
  • Load Cell Calibration
    • Tension, Compression
  • Push Pull Tester
