Model: Multi Tester JE
Thank you for buying this Multi Tester of SAUTER. We
hope you are pleased with your high quality product and
with its functional range. If you have any queries, wishes or
helpful suggestions, do not hesitate to call our service
number.
The Multi Tester utilises the feature that diamonds have a
very high thermal conductivity. So it can effectively and
quickly distinguish natural diamonds from all kinds of
diamond simulations and metals, except synthetic
moissanites (a man-made stone), which have a thermal
conductivity similar to diamonds.
The lights (and a distinctive sound which accompanies
each light) will indicate Diamond, Moissanite, Metal Alert
Metal Alert usually because the jewellery has been
touched by accident). Other stones like ruby, sapphire,
topaz give no reaction at all (including glass and cubic
zirconia). These various readings (Diamond, Moissanite,
Metal, no reaction) show that the Multi Tester works
accurately on the largest number of gemstones.

1. Features
- 360 degree illumination around the front of the Multi
Tester allows the user to see the test results clearly and
comfortably without having to angle the tester.
- Fitted with a 0.6mm diameter fine retractable
thermoelectric sensor, giving consistent pressure when
being placed on the surface of a gemstone, ensuring
accurate results, even on tiny stones.
- Non-slip rubber coated body allows a better handling
during the tests.
- The built-in metal alert lets you know if the jewellery
setting or the stone holder has been accidently touched. It
helps the user to reduce false readings
- There can be tested stones mounted in jewellery or loose
stones (stone-holder included)
- There are different sounds for diamond, Moissanite and
metal which facilitate to distinguish the test results without
having to look at the lights
- An integral UV light can be used during a test to give
more accurate readings when testing Moissanites (it
excites the atoms and improves electrical conductivity). It
can also be used to observe the fluorescence in diamonds
for the purpose of colour grading.
- There are no waiting times between the tests
- Designed for left and right handed users.
- Fully automatic, requires no calibration by the user
- powered by one 9V monobloc standard battery
- Alarm sounds after a few minutes if the power is
accidentally left on and it automatically powers off
-The diamond tester can be connected with an AC adapter
for a long time indoor use (not included in delivery). It has
got a 2 years manufacturer’s warranty.
