Engineering, testing and calibration services

Simtars offers testing services for explosion protected electrical equipment.

We have close to 30 years of experience helping equipment manufacturers and equipment operators associated with underground coal mines, oil refineries, petrol stations, grain silos, sewerage treatment plants and processing industries

Calibration services

Our calibration laboratory specialises in calibrating equipment to meet compliance requirements, and is accredited by the National Association of Testing Authorities (NATA) under the AS ISO/IEC 17025 standard. The service supports our testing activities and is available to general industry.

Each calibration is accompanied by detailed reporting of the calibration outcome and/or data.

Gas detectors

We are NATA-accredited to calibrate a range of gas detecting and monitoring equipment. The accreditation covers specific gases, detector types and concentration ranges, for example:

  • carbon monoxide: by electrochemical sensor over a 0.0001-1% range
  • methane: by pellistor sensor over a 0.0001-5% range
  • oxygen: by electrochemical sensor over a 0.0001-25% range.

Personal sampling pumps

We are also NATA-accredited to calibrate personal sampling pumps. The accurate calibration and performance testing of personal sampling pumps enables accurate calculation of sampling volume. Accurate sampling volume is critical when determining the airborne concentration of a substance collected.

Simtars can perform a full range of sampling pump tests based on the requirements of the Australian Institute of Occupational Hygiene’s Technical Paper ‘Air Sampling Pumps: Equipment Calibration Requirements’ including:

  • Back pressure flow rate
  • Timer functions
  • Low battery final flowrates
  • Maximum compensation range back pressure
  • Delayed start / time run tests
  • Flow fault indication
