Tools such as torque wrenches, oil pressure gauges, radiator pressure gauges, tyre pressure gauges, shim micrometers etc are all purchased for the sole purpose of measuring a quantity. This equipment is usually, but not always, accurate within specified limits when purchased new but the accuracy diminishes over a period of time depending on usage. Look through your service/repair manuals, all contain measurements that are required to be met but how can you be sure you are meeting those requirements?

If periodic accuracy checks are not being carried out on your measuring equipment then their use may be detrimental to the functioning of the product they are being used on.


More than 75 companies throughout Tasmania have varying amounts and types of measuring equipment calibrated by Calspec. That is over 75 companies that we personally know of who understand the importance and value of having calibrated inspection, measuring & test equipment.

We calibrate equipment for companies that range from passenger airlines to manufacturers such as Caterpillar Elphinstone and Incat to tyre retailers and plumbing service companies.


Safety is an issue with which we should all be concerned with and no more so than when supplying a service to others. We hear of cases where items of inaccurate measuring equipment have been used with disastrous outcomes which could have had fatal consequences, for instance a wheel coming off a moving heavy vehicle whch thankfully only damaged several cars.

The safety aspect associated with the use of uncalibrated equipment should not be ignored.


Every now and then we have equipment given to us from companies where the operator feels that it is not measuring accurately. We understand that staff who use measuring equipment regularly get a “sixth sense” that the equipment is not quite right. In some cases a spot check can determine if their ‘feeling’ is correct or not.

If your company has equipment calibrated regularly by Calspec we can carry out spot checks on equipment in the interval between recalibrations and if the accuracy is found to be acceptable there will be no charge (subject to conditions) for that spot check.


Having your equipment calibrated may also allow potential faults to be detected and fixed before they present a problem.

More benefits to equipment calibration.


Regardless of how many times your I.M & T equipment is used it should be checked for accuracy, even if only once per year. The cost is proportional to the care & usage of the equipment. Calibration may only be required once or twice a year.

Cost is minimal when compared to potential benefits.

Calibrating a Test Gauge on a Dead-Weight Tester
Pressure Gauges & Pressure Transducers
Oil tested to 120,000kPa (16,000 PSI) for both industrial and test (master) gauges
Water tested to117,000 kPa (17,000 PSI)
Vacuum Gauges

The combined error and uncertainty of the dead-weight tester is less than 0.025% of the developed pressure or 2.5 kPa whichever is the greater with a coverage factor of 2 @ 95% confidence level.



Torque Wrenches
Our testing equipment is capable of testing torque wrenches up to 1400Nm (1000ft.lb.)

The combined error and uncertainty in the highest torque range is less than 0.7% with a coverage factor of 1.96 @ 95% confidence level.
