Your weighbridge sets the price. Your certificate says whether it counts.
Truescale verifies, calibrates and repairs weighbridges, platform scales and axle scales across the Perth industrial corridor and the Wheatbelt.
Servicing licence SL0000 · 20 t of test weights · every brand, and we sell none
We are not an equipment supplier, so the answer to can this one be fixed is never coming from someone who would rather sell you a new one.

What we do on site
Prices are per instrument, on site, inside the metro band. Country work is quoted with the travel shown as its own line, shared when we are already running that way.
Trade verification
Platform scale from $180
Testing to the national instrument test procedure for your subclass, then the verification mark if it passes. Platform or pallet scale from $180, axle or wheel scales from $420, weighbridge from $890.
Calibration to a stated tolerance
From $240
For instruments that do not set a price: tested against the tolerance you nominate, with a certificate of accuracy. No verification mark, because none is required.
Load-cell fault-finding
From $310
Corner-by-corner readings, cable and junction-box checks, summing card and excitation voltage. Half a day on site. Parts quoted before we fit anything.
Indicator and printer repair
From $190 plus parts
Displays, keypads, ticket printers and the serial or Ethernet link back to your weighbridge software. If the board is dead we say so instead of quoting a whole indicator.
Axle and wheel scale service
From $420
Portable pads and wheel scales checked as a set, on the mats and the ground you actually weigh on, because a pad on soft gravel is not the pad we tested in the workshop.
Pre-purchase inspection
From $760
Before you buy somebody’s decommissioned bridge: deck, load cells, pit drainage, approaches, and whether its certificate of approval actually covers what you want to weigh.
Does yours need verifying, and when?
Due in 1 month
Book it before your certificate date passes. We bring the weights, run the test procedure and leave the certificate with you.
Weighbridge verification, from $890 on site in the metro band.
We do not quote fines. What a lapse costs is a matter for the National Measurement Institute’s trade measurement inspectors, and we will not publish a number we cannot source.
No interval applies to an instrument that is not used for trade, so these two are switched off.
The interval is yours, not ours. The National Measurement Institute publishes no fixed re-verification interval: an instrument used for trade must be an approved pattern, verified before it is used and verified again after any repair or adjustment, and you carry the duty to make sure it weighs correctly at all times. The date most sites actually work to comes off their own certificate, their quality procedure or a customer’s contract — so this asks you for it.
How a verification runs
Four steps, usually one visit. A weighbridge takes most of a morning; a bench scale takes twenty minutes.
Data plate and approval
We read the data plate and check the certificate of approval covers the instrument as it is actually installed — capacity, load receptor, indicator, and whether you are weighing direct or end-and-end.
Weights on the deck
Certified test weights, the national instrument test procedure for your subclass, and the tests that catch the faults you cannot see: eccentricity, repeatability and the full range, not just one pass at capacity.
Adjust, then mark
Inside the limits of error, it gets the verification mark and the seals. Outside them, we fix it first and test it again. We will not mark an instrument we have not proved.
The paperwork
A certificate of verification goes to you and the notification goes to the NMI, with a test report where the subclass calls for one. You get a plain sheet showing what each corner read, so the next person can compare.
Three we look after
“Certificate lapsed on a Friday and we had trucks going out Monday. Weights were on the deck Tuesday morning and the paperwork was in my inbox that afternoon. They also told me the ponding at the western approach would fail us next time, which nobody had mentioned in six years.”
Rob M. · quarry · Byford
“The mob who sold us the bridge quoted a new indicator. Truescale found a corroded junction box, replaced it for a fraction of that, and every corner came back inside tolerance. We have not been offered a machine since, which is the point.”
Deb S. · metal recycler · Bibra Lake
“Two platform scales and the bridge, all on one run, travel billed once. Before that we had two suppliers and three invoices. The report tells me what each scale actually read, not just pass or fail.”
Anthony K. · grain receival · Northam
These reviews are written as demonstration copy for a fictional business. They are not real customer reviews and are deliberately not marked up as review data.
Drive time, not postcodes
We work out of Welshpool. What decides your date is how far the truck and the weights have to travel, so this map is drawn in drive-time bands rather than a list of suburbs we claim to cover.
-
Under 45 minutes
Welshpool, Kewdale, Bibra Lake and the Kwinana strip. Booked same day for a breakdown, next day for a scheduled verification.
No travel charge inside this ring.
-
45 minutes to two hours
Neerabup, Wundowie and the eastern hills. Scheduled inside the week, and we will tell you which day we are already coming past.
Travel billed once per site visit.
-
The Wheatbelt run
Northam, Merredin and the receival sites between them. We run east on a set fortnight, so several sites share one lot of travel.
Travel split across the sites on the run.
What site managers ask us
How often does a weighbridge have to be re-verified?
There is no fixed re-verification interval published for trade instruments. What the law requires is that the instrument is an approved pattern, that it is verified before it is used for trade, that it is verified again after any repair or adjustment, and that you make sure it weighs correctly at all times. The National Measurement Institute’s advice is to have it tested regularly.
In practice the date you work to comes from somewhere concrete: the interval printed on your last certificate, your own quality procedure, or a customer’s or auditor’s contract. That is why the checker on this page asks you for the interval instead of telling you one. Twelve months is the most common answer and it is the default here, but yours is whatever your paperwork says.
Our scale does not set a price. Do we still need it verified?
No. Trade measurement applies where the measurement determines a price. If your instrument only feeds stock control, a production report or a load-safety check, it does not need trade verification and we will not quote you for one.
That does not mean the number does not matter. If you want it to be right, we will calibrate it against a tolerance you nominate and give you a certificate of accuracy. It is a different job and a cheaper one.
What is the difference between verification and calibration?
Verification is a legal act. A servicing licensee tests the instrument to the national instrument test procedure for its subclass, confirms it operates within the limits of error permitted under the regulations, and applies a verification mark. That mark is what lets you trade on the ticket.
Calibration is a measurement exercise. We tell you what the instrument reads against known weights, and you decide whether that is good enough for what you are doing. No mark, no legal status, and it is available for any instrument, trade or not.
Do you sell weighbridges or scales?
No, and it is deliberate. Most of the businesses that come up when you search for weighbridge calibration in Perth are equipment suppliers, and their servicing page sits underneath a product catalogue. That is a fair way to run a business, but it means the answer to “can this one be fixed” is being given by somebody who would rather sell you a new one.
We only sell labour and parts. If your twenty-year-old bridge can be brought back inside tolerance with a junction box and a day of work, that is the recommendation you will get.
What will it cost us if the certificate has lapsed?
We are not going to put a number on that. Penalties under the trade measurement law are a matter for the National Measurement Institute and its trade measurement inspectors, and we will not publish a figure we cannot source. Anyone quoting you one on a sales page is guessing.
What we can tell you is the practical cost, which is usually the bigger one: a customer disputing tickets, a load rejected at the gate, or a month of weights nobody can stand behind.
Our approaches are cracked and ponding. Does that matter?
Yes. A weighbridge’s approaches are part of the installation and have to comply with regulation 3.4 of the National Trade Measurement Regulations 2009. Water sitting in the pit or against the deck, debris packed between the platform and the surround, or a broken approach slab will all move the number before the load cells get a say.
We check the approaches on every visit and tell you what we found, in writing, whether or not it affects the result on the day. Concrete work is not something we do — we will just tell you what needs doing so you can get it priced properly.
Get a date and a price
Fill this in and we will call you back within one business day with a date and a figure — or tell you that you do not need us, which happens often enough to be worth saying up front.
Got it — that is enough to book from.
We will call you back within one business day with a date and a price. If the answers say you do not need a trade verification, we will tell you that instead and there will be no quote attached to it.
