If you have purchased a Presidium Gem Tester, it will come with two thermometers, one digital and one analog. The digital thermometer displays a digital color coded value while the analog thermometer measures the absolute temperature of the gemstone while it is being tested. The difference in temperature produces an electrical output that is displayed on your Gem Tester's front. The Analog Dial on your Presidium Gem Tester II helps you to easily distinguish between various gemstones by indicating their temperature with a colored stone estimator.
To help you understand how a presidium gem tester works, first know what gemstones are placed inside the thermometer. Most people will use their finger as the pointer and place their hand inside the device. A probe with an infrared light is inserted into the stone which has a small metal ring attached. As the infrared light passes through the ring, the inside of the stone will rapidly heat up. The infrared probe detects the heat which is then measured and displayed on your Presidium Gem Tester's front.
The thermometer I've found uses a small, solid colored stone called "Aventurine" which is found in Australia. The infrared energy emitted by this stone is measured using a tiny, solid colored glass plate called "etch." This process is extremely sensitive and needs precise measurements in order to detect even the slightest variations. The reason why this product is so accurate is because the infrared energy emitted by Aventurine is actually similar to the invisible infrared energy emitted by our own sun. This allows the Presidium Gem Tester to gauge the temperature of the inside of a precious stone at many points along the stone's surface.
This is how a Presidium Gem Tester works. When you buy one another based on color, cut, clarity, carat and clarity of stone, you're looking at a measurement of how shiny the stone is. However, many factors come into play when determining how shiny a stone is. The shape, cut and carat of a stone can all affect how shiny it is and therefore how expensive it is. With the help of a Presidium Gem Tester you can easily determine if a stone is the right fit for you or one that should be rejected.
The two most popular types of testing gemstones are digital and analog. Digital tests use digital values to display the data from the tests gemstones are subjected to. They are very easy to read and they are usually larger print sizes than their analog counterparts. This is why many people prefer them to these common colored gemstones testers. However, there are some disadvantages to using digital tests.
Most of them work on single colors. However, there are some that have an extended range of colors that you can select from. There are also some that have an extended range of inputs so that you can use both the touch and the voice. Some of them have the advanced intelligent results display function where you can find out the percentage match between two of your chosen common colored gems even if they're of different hues. They have an advanced memory function that lets you keep track of the longest matched pair of hues of any pair of common gems.
All the tested Presidium Gem Testers have been equipped with an extended range of functionalities. They have a crystal clear display that allows you to view the result of all the tests in a separate window. Some of the models allow you to run several tests simultaneously so that you can compare their results individually. Then there is the "Real Time" function which is a self calibration option that ensures accurate results for all tests. This option also has an automatic shut off feature. The last, but not the least among the functionalities is the "colour transfer" function that transfers the colours of your choice from the device's monitor onto the colour of your gemstone.
When buying a Presidium Gem Tester, it is essential that you choose one that is compatible with your laptop or desktop. It is also important that the software program is compatible with your computer's USB port so that all the transfer functions run smoothly. If you have any doubts while making your purchase, it is recommended that you use the online service provided by a number of reputable manufacturers. This ensures consistent and reliable results for all your gemstone testing requirements.
