Gold purity, karat and the metals in the alloy, on a screen built into the machine.
The Signet PC is a benchtop XRF gold testing machine for the jewellery counter. The Windows computer sits inside the cabinet and the touch screen is set into the front, so there is no laptop or separate computer to connect. You place the piece in the chamber, close it and start the test. The screen shows the gold percentage and the karat to ±0.50% on gold content, along with the other metals in the alloy, 7 metals in one test. Nothing is cut, filed or touched with acid, and the piece goes back to the customer as it came in.
The machine sends an X-ray beam at a small spot on the piece. Each metal in that spot answers with X-rays at its own energy. The Si-PIN detector picks up those signals, and the software on the built-in computer counts them to give the percentage of each metal. The karat is worked out from the gold percentage. The beam does not remove or change any metal, which is why the test leaves no mark.
No acid, no chemicals and no sample preparation.
| What is built in | What it means at your counter |
|---|---|
| Windows computer inside the cabinet | No laptop to keep charged and no tower under the counter |
| Touch screen in the front panel | Start the test and read the result on the machine itself |
| Keyboard and mouse as well | Type customer names and reference numbers instead of tapping them |
| Full Windows desktop | Your own billing or stock software can run on the same computer |
| Analyzer software supplied | Set up by our engineer at installation, matched to the detector |
| What you need to know | What the Signet PC shows |
|---|---|
| Is this piece the karat it is sold as? | The gold percentage to ±0.50%, and the karat from it. A piece sold as 22K that reads lower shows up at once. |
| What is the gold mixed with? | The other metals in the alloy, each as a percentage, 7 metals in one test |
| What to pay for old gold | A gold figure to value the piece on, before you pay or exchange |
| What to lend against | The gold content of a pledged piece, before the loan amount is set |
XRF reads the metal the beam reaches, which is the surface of the tested spot. A gold-plated piece, or a bar with a different metal inside, can read as its outer layer. If the weight, feel or origin of a piece does not match its reading, check it further before you buy.
| Test | How it compares with the Signet PC |
|---|---|
| Acid test | Needs a scratch and acid on the piece, and gives a karat range. The Signet PC gives a percentage without marking the piece. |
| Touchstone | Rubs a streak of metal off the piece onto a stone, then compares it by eye with test needles. The Signet PC takes nothing off and gives a figure. |
| Conductivity tester | Measures how well the metal carries electricity, to screen coins and bars. It does not list the metals in the alloy or give a karat. The Signet PC does both. |
| Fire assay | Melts a cut sample in a laboratory and is the reference method for purity. It destroys the sample and takes hours. The Signet PC gives a reading at the counter. |
Gold jewellery of every kind: rings, chains, bangles, earrings, pendants and necklaces, including pieces with stones set in them. Gold coins and small bars. Old gold brought in for exchange, resale or as a loan pledge.

A benchtop XRF gold testing machine from Semsons Tech, with the Windows computer and touch screen built into the cabinet. It shows the gold percentage, karat and the metals in a piece's alloy without damaging it, and needs no separate computer.
It sends an X-ray beam at a small spot on the piece. Each metal answers with its own X-ray signal, and the machine counts those signals to give the percentage of each metal and the karat. Nothing touches the piece.
No. There is no acid, no scratching and no filing. The piece comes out of the chamber exactly as it went in, so it can go straight back to the customer.
±0.50% on gold content. On a 22K piece, which is 91.6% gold, the reading falls within half a percentage point either way. That is close enough to tell a 22K piece from a lower karat.
No. The Windows computer is inside the cabinet and the touch screen is on the front. A keyboard and mouse connect to it for typing customer details. The Signet FSDD and Signet Si-Pin, by contrast, run from a PC you supply.
XRF reads the metal at the surface of the tested spot. A gold-plated piece can read as gold, and a bar with a different metal inside can read as its outer layer. If the weight, feel or origin of a piece does not match its reading, check it further before you buy.
The chamber is shielded and has an interlock: the X-ray stops when the chamber is opened, so the test runs only with it closed. Our engineer goes through safe use with your operator at installation.
Yes. Place the piece so the metal, not the stone, sits over the test spot. The stones do not have to be removed.
An XRF machine reads which metals are in the piece and how much of each, so it gives the karat. A conductivity coin tester measures how well the metal carries electricity. It screens coins and bars, but it does not list the metals or give a karat.
The full product price and the booking amount per machine are shown at the top of this page, and both include GST. The booking amount counts toward the full price, and the balance is due on installation.
It is not sold through online checkout. Book 1 or 2 machines through our sales team on WhatsApp or by phone, with the booking amount paid for each machine.
Dispatch is about 30–40 days from booking, and delivery is free. Returns are not accepted. If a manufacturing defect is verified on inspection, a replacement may be considered, subject to the product and service terms.
Our engineer installs the machine, sets up the software and trains your operator on site. EMI options are available through partner banks. Service across 16+ Indian cities.
