Six points to buy an Ultraviolet-visible spectrophoto-meter

 Looking to buy a UV-Vis Spectrophotometer , how can you not know some selection tips? Knowing more about the skills will definitely allow you to buy the photometer you want. We specialize in the production of UV-Vis Spectrophotometer s here. Let's take a look at these selection skills together!

   The first point: the problem of optical accuracy, each user has different requirements for accuracy, so the selected instrument will be different.

   The second point: the treatment of astigmatism, astigmatism seriously affects the measurement of the instrument, resulting in the size of the error, of course, the smaller the astigmatism value is, the more accurate it is, it is recommended to use a UV-visible Spectrophotometer .

   The third point: The problem of spectral bandwidth is that the smaller the value, the more accurate it is. If the beam is too weak, it will seriously affect the sensitivity of the instrument and fail to achieve the required results. Therefore, you must be careful when choosing.

   The fourth point: the stability of the instrument, such a precise instrument needs to have good stability.

   The fifth point: the problem of noise processing, which is also the key point to verify the performance of the instrument, and the smaller the value, the more accurate it is.

   Sixth point: the accuracy of the wavelength, the actual measured wavelength of the substance is very different from the standard wavelength, then the measurement of this substance will fail, so we hope you choose a UV-Vis Spectrophotometer , which can perform high-precision measurement deal with.
