Gold Purity Testing Machine Dubai: Prices, Features and Buying Guide
Quick answer: The price of a gold purity testing machine in Dubai depends on the technology (XRF analyzer, pen-probe tester, or bar and coin verifier), the detector and accuracy, whether it is benchtop or handheld, and the software, connectivity, warranty, and support that come with it. Entry-level pen-probe testers sit at the lower end, XRF analyzers at the higher end, and the right choice depends on what you test and how often. We don’t publish list prices here, because configurations and quotations vary; you can request a quotation for your exact needs. Telos Instruments, based in Deira, Dubai, supplies the Terra Scientific Aurora 900, Pi900E, EulerX 900 and 900S XRF analyzers, the GemOro AuRACLE PRO, and the Sigma Metalytics PMV range, and is the exclusive distributor of GemOro and Sigma Metalytics in the UAE.
This guide explains what you’re paying for, which features matter, and how to choose the right machine for a jewellery shop, buy-back counter, refinery, or bullion business.
What Drives the Price of a Gold Purity Testing Machine
1. The testing technology
- XRF analyzers use X-ray fluorescence to measure full elemental composition without touching or marking the piece. They involve an X-ray source, a detector, and software, so they sit at the higher end.
- Pen-probe testers like the AuRACLE PRO use an electronic probe on a small filed spot and display karat and gold percentage. They cost less, and they’re a screening tool.
- Bar and coin verifiers like the Sigma Metalytics PMV test resistivity (and density on some models) and are built specifically for bullion.
2. Detector quality and accuracy
In XRF analyzers, the detector is a key cost driver. Silicon drift detectors (SDD), used in the Terra Scientific analyzers covered here, separate the signals of closely spaced elements more cleanly and support precise readings.
3. Benchtop vs handheld
A benchtop unit like the Aurora 900 is designed for a fixed counter; handhelds like the Pi900E and EulerX series add ruggedness, batteries, and portability.
4. Software, display, and data handling
Touchscreens, stored records, WiFi, USB, and Bluetooth connectivity, and optional apps add convenience and cost, and matter if you need documentation.
5. Metals and calibration coverage
An analyzer that reads gold, silver, platinum, and palladium, or has multiple calibration options for precious metals, scrap, and alloys, offers more flexibility than a gold-only tester.
6. Build, certification, and safety features
CE, RoHS, and IP54 certification, rugged housings, and radiation safety features such as automatic source shutoff all contribute.
7. Warranty, training, and local support
A UAE-based supplier who can demonstrate, train, and support the instrument reduces downtime and risk, which has real value over the instrument’s life.
8. Accessories
Test stands, calibration references, printers, and balances all add to the total cost of a working setup.

Safety and Compliance in the UAE
XRF analyzers contain a low-level X-ray source, so import, registration, and use may require approval from the relevant UAE authority. The Pi900E and EulerX analyzers include automatic source shutoff when no sample is present, and operators should follow standard radiation-safety practice. Ask Telos Instruments to guide you through the paperwork before you buy.
How to Get a Quotation
To receive an accurate quotation from Telos Instruments, share:
- What you test (jewellery, scrap, bars and coins).
- How many tests per day.
- Where you test (fixed counter or multiple sites).
- What you need to document (records, customer-facing results).
- Your current equipment (balances, existing testers).
- Accessories you want (balance, references, stands).
- Timeline and quantity.
The more specific your request, the more useful the quotation, and you can ask for a demonstration on your own pieces before you decide.
Common Mistakes When Buying
- Choosing by price alone. A cheaper tester that can’t catch plating can cost far more in a single bad purchase.
- Buying a PMV to test jewellery or a pen-probe tester to verify bars.
- Ignoring weight. A certified balance is part of the setup.
- Skipping compliance checks for XRF equipment.
- Not seeing it work on your own pieces.
- Overlooking support. Calibration and servicing are easier with a local supplier.
Frequently Asked Questions
How much does a gold purity testing machine cost in Dubai?
Prices vary by technology, detector, benchtop or handheld format, features, warranty, and accessories. We don’t publish list prices; request a quotation from Telos Instruments for your needs.
Why are XRF analyzers more expensive than pen-probe testers?
They include an X-ray source, a precision detector, and software, and they provide non-contact testing with full elemental composition and plating detection.
What is the best gold purity testing machine for a jewellery shop?
For most established shops, a benchtop XRF analyzer such as the Aurora 900. Smaller shops often start with the AuRACLE PRO and add XRF as they grow.
Does the AuRACLE PRO damage jewellery?
It requires a small filed spot, so it leaves a small mark. XRF analyzers are non-contact.
Can one machine test jewellery and bars?
XRF analyzers can test both at the surface, but bars should also be checked with a sub-surface verifier such as the Sigma Metalytics PMV. PMV devices are for coins and bars only.
Do I need to register an XRF analyzer in the UAE?
Import and use may require registration with the relevant authority. Telos Instruments can guide you.
Who are the exclusive distributors for GemOro and Sigma Metalytics in the UAE?
Telos Instruments, based in Al Uthman Building, Deira, Dubai.
Where can I buy a gold purity testing machine in Dubai?
From Telos Instruments, with demonstrations and local support.
Final Thoughts
Price is only one part of the decision. The right gold purity testing machine is the one that fits what you test, how often, and how much a mistake would cost you. A pen-probe tester like the AuRACLE PRO is a sensible start, an XRF analyzer like the Aurora 900 is the standard for serious counters, a handheld like the Pi900E or EulerX goes where the stock is, and a PMV covers bars. Telos Instruments supplies the whole lineup from Deira and can quote a setup to match your business.
