Calibration Services
Accurate Calibration Services for Instruments, Test Meters & Gauges
Our ISO 17025 accredited calibration laboratory is able to facilitate the calibration of a wide variety of testers ranging from electrical meters, such as multimeters and clamp meters, to specific testers such as barometers, vacuum gauges, anemometers, digital thermometers and much more. We also calibrate several tools including torque screwdrivers and wrenches, steel rules, theodolites and vernier calipers. DOPET is certified to carry out calibration services for a wide range of instruments, (pneumatic to smart type), with the following ranges: Pressure -0.8 to 20 bar pneumatic & 0 to 1,400 bar hydraulic, Temperature -350C to 1,1000C, Thermocouple calibrator -2000C to 1,3700C
Dimensional Calibration
Gauge Calibration – Tool Calibration – Mechanical Calibration
Our accredited dimensional calibration laboratory caters for standard mechanical gauge and tool calibration, such as micrometer calibration, thread gauge calibration, or calibration of gauge blocks.
Electrical Calibration
Meter Calibration – Tester Calibration – Electrical Stds
With an electrical calibration capability on frequency up to 20GHz, voltage up to 40kVDC and current up to 1000ADC, we can provide calibration on most types of DC or LF electrical tester or meter, from handheld field instruments to laboratory standards.
Bench type equipment such as counter timers, long scale multimeters, oscilloscopes and power supplies are also covered by our electrical accreditation.
Force Calibration
Force Gauge, Load Cell, Scales and Weight Calibration Services
In our calibration laboratory for mass we can weigh dead-weight tester masses from 0.1g to 20kg with uncertainties of 0.5mg, 15mg and 0.0003 % of reading, depending on the mass range. For the calibration, in our calibration laboratory, we only ever use high-accuracy electronic mass comparators and reference weights.
Pressure Calibration
Pressure Gauge Calibration – Instrument Calibration Services
In our calibration laboratory for pressure we calibrate measuring instruments in the measuring range from 10 mbar absolute … +5,000 bar gauge with uncertainties of 0.004 % … 0.01 % of reading, depending on the pressure range. For the calibration, in our calibration laboratory, we only ever use high-accuracy references such as dead-weight testers, digital piston gauges and pressure controllers.
For dead-weight testers we offer two types of calibration – ‘pressure equivalent calibration’ where we compare the pressure generated by a dead-weight tester against a reference standard at a number of points over the range or ‘area calibration’ where we determine the effective area of the piston-cylinder unit over the range of the instrument.
Temperature Calibration
Contact Thermometer and Infrared Thermometer Calibration
Our temperature laboratory uses a range of reference platinum resistance thermometers, noble metal thermocouples, stirred liquid baths, specially designed isothermal calibration furnaces and black body sources to provide a comprehensive facility for cost effective thermometer calibration or temperature probe calibration over the range -80ºC to 1,200ºC. We can even calibrate temperature sources such a dry block calibrators or calibration baths.
Torque Calibration
Torque Wrench Calibration – Torque Tool or Meter Calibration
Regular torque tool calibration ensures repeatable accuracy and adherence to international standards. In addition to torque wrench and screwdriver calibration we also calibrate a wide range of other equipment’s like torque closure meters, analyzers etc.
