Force and post-tensioning
Hydraulic jacks, jacking systems and load cells for post-tensioning, civil and structural work.
Fields and industries
Every field, every instrument, one system
A field is a kind of laboratory rather than a category of instrument. You choose what you do, and the instrument catalogue, the saved check plans, the standards cited and the document produced all follow from it. 13 fields and 57 instrument types, and a laboratory that does two of them never sees the other eleven.
9 fields · ISO/IEC 17025
Calibration — what an instrument reads against a reference
These produce a calibration certificate: traceability to national standards, a stated uncertainty, the declared decision rule, and a grade where the method defines one.
Electrical test instruments
Multimeters, clamp meters, insulation, RCD, appliance and multifunction testers — the instruments an electrical contractor tests with.
RF and optical
Spectrum and network analysers, optical sources and power meters.
Pressure and temperature
Pressure gauges and transducers, thermometers, probes and thermal imagers.
Torque
Torque wrenches, screwdrivers and testers.
Dimensional
Calipers, micrometers, length standards, coating thickness gauges.
Gas and environment
Gas detectors, anemometers, sound level meters, moisture meters, flow meters.
Medical devices
Blood-pressure monitors, scales, oximeters, glucometers, dopplers and ABI machines in medical centres and practices.
Site and workshop equipment
Laser levels, welding machines, metal detectors, tint meters.
4 fields · in-service inspection
Inspection — whether an item met a standard’s criteria
These produce an inspection report. It states the criteria, the readings and the outcome, and asserts nothing about the item’s measurement accuracy, because nothing was measured about it. No grade, and never an accreditation mark.
Test and tag — in-service inspection
Testing and tagging appliances, leads and RCDs in service. High volume: hundreds of items a day, most of them passing.
Electrical safety equipment
Insulating gloves, mats and blankets — proof-tested rather than calibrated.
Lifting and height safety
Slings, chains, harnesses and lifting equipment inspected for continued service.
Medical equipment safety testing
Electrical safety and performance verification of medical equipment — beds, autoclaves, nebulisers, examination equipment — under AS/NZS 3551.
Why the difference is enforced rather than documented. The discriminator is the item, not the shape of the check. A 500 V insulation tester must deliver at least its rated voltage at rated current under AS/NZS 3763 — a one-sided limit inside a genuine calibration. Calibrating an RCD tester against a reference is calibration; testing an RCD in a switchboard is inspection. Same standard, same measurement, different document, because the item is a different kind of thing.

Electrical test and tag, in depth
The largest of the thirteen fields by volume, and the least like the others. Hundreds of items a day rather than one instrument in an afternoon, almost all of them passing, and an inspection report at the end rather than a certificate.
The batch grid, not the bench sheet
Hundreds of appliances, leads and RCDs a day, entered across a grid rather than down a form. The bench sheet is right for one jack in an afternoon and wrong for a pallet of kettles, and the two sit beside each other so a technician chooses by what is on the trolley.
One-sided limits, properly modelled
AS/NZS 3760 bounds earth resistance in one direction only — ≤ 1 Ω, with nothing to say about how much lower is better. A tolerance band with a lower limit invented to fill the field is a fabricated criterion on a safety document, so the engine carries genuine one-sided limits and go/no-go checks with no numeric reading at all.
An inspection report, and never a certificate
An appliance is not calibrated, and heading its document “Calibration Certificate” tells a reader something that cannot be true of a kettle. The discriminator is the item rather than the shape of the check, it is stored on the document at issue, and the accreditation mark is refused rather than explained in a footnote.
Test tags that say next test due
The tag on the appliance reads the date the person holding it needs, printed as ZPL straight to the printer. It carries a QR code like everything else, so a site supervisor can check the item without an account, an app or a phone call to your office.
Three months on a site, twelve in an office
The interval is the customer’s environment rather than a property of the appliance, and the same kettle is due at different times in different places. Intervals are set per instrument type and overridden per item, and the recall ladder follows whatever was actually recorded.
Recorded where there is no signal
A switchboard room, a basement, a construction site. Readings are captured on the device and sync when it reconnects — and the engine deliberately does not run offline, because everything that makes the document defensible depends on checks that cannot run on a handset.
57 instrument types
The catalogue
Sorted by physical quantity rather than by field, because the two are different questions: “Electrical” holds a spectrum analyser and an appliance tester, and no business does both. Each type carries a default interval and a pinned calculation template — and a laboratory may add its own, because a catalogue is a starting point and not a ceiling.

The interval is advice, not a rule. It is the laboratory’s decision and in some fields the customer’s environment decides it — test and tag is the clearest case, at three months on a construction site and twelve in an office, for the same appliance either way.
Not seeing your field?
Nothing stops a laboratory booking in an instrument outside the fields it chose, and a new instrument type takes minutes to add. Three disciplines are sold separately because each carries its own standard and its own assessment rather than more of the same work: medical (AS/NZS 3551), hazardous areas (AS/NZS 60079) and legal metrology.
