Frequently asked questions

Some of the frequently asked questions to us

Can I calibrate the breathalyzer myself?
No. In order for the breathalyzer to take measurements with a maximum accuracy, you have to calibrate it with a special equipment, available only in our service centers. This procedure does not take much time - usually 30-40 minutes (does not include time required for other procedures, e.g. checks or repairs).
The breathalyzer was not used for a long time. Does it need to be recalibrated?
Over time, the accuracy of the breathalyzer sensor measurements deteriorates, even if the device was not used. Therefore, if you decide to start using the breathalyzer again, you must first calibrate the sensor.
What is the delivery time for the equipment?
<p>Concerning the delivery time, except for products in stock, the delivery time may vary considerably depending on the equipment/product. Please contact us in advance for more precise delivery terms and conditions.</p>
Do you have a guarantee and quality certificates for the supplied equipment?
Of course, the entire package of documents required for the delivery of equipment is present, including a guarantee with all certificates.
What are monocrystals?
Monocrystals are single crystals in whichl in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. Monocrystals often have the correct shape, but this feature is not even asked when determining the type of crystal. Most of the minerals are single crystals. Their shape depends on the growth rate of the substance. With a slow increase and uniformity of the material, the crystals have the correct cut,and with a medium speed, the cut is not pronounced. At a high crystallization rate, polycrystals, consisting of many single crystals, grow. Classic examples of single crystals are diamond, quartz, topaz. In electronics, monocrystals with the properties of semiconductors and dielectrics are very important. Alloys of single crystals are characterized by increased strength. Ultrapure single crystals have the same properties regardless of origin. The chemical composition of minerals depends on the rate of growth. The slower the crystal grows, the more perfect its composition.
What are artificial monocrystals?
Growing monocrystals is possible due the current level of science. While processing metal, without changing its composition, it is possible to create a monocrystal that has a high margin of strength. There are 2 known methods for the production of monocrystals: ultra-high pressure and metal casting; cryogenic pressure. The first method is popular in the processing of light metals. Due to the purity of the metal and an increase in pressure, a new metal will gradually appear with the same properties, but with increased strength. If certain conditions are met, a single crystal with an ideal lattice can be obtained. For heavy metals, with increasing pressure, a process of structural change occurs. Cryogenic casting is based on the production of cryogenic liquids. Crystallization does not occur if there is a magnetic field. The semi-crystalline form becomes a crystal upon electrical charge.
