Duo gem tester (Presidium PDT-II) Digital scales - regular lines - resolution 0.1g I like it not having

I like it not having an extra inset lens

but there isn't much room to fit stones mounted in jewellery

we change the price of these samples each week

exceptionally high quality

For the professional jeweller: from 3 points is safe

Duo gem tester (Presidium PDT-II) Digital scales - regular lines - resolution 0.1g I like it not havingSummary Bench model. A dual tester with both thermal meter and reflectivity meter. Place the probe on the stone to operate analogue meter (the thermal meter, see detail in the extra pictures). Place the stone over the sensor (even if it's in jewellery) to operate the digital meter (the reflectivity meter). You don't have to use both systems, you can choose one or the other. Includes heavy duty nylon carrying case and a PPR3 battery. Also power supply
