Choosing a refractometer: types and features

To determine the refractive index of light, useispecialand opticaland instrumentAnd – refractometerAnd. Principle eatx work consists in measuringand angle of refraction of light rays through the medium. Density affects the indicator substances. The higher it is, the higher the refractive index. The obtained indicators are analyzed according to with scalescarving Brix.

Features of the optical measuring device

Optical measuring devices, such as refractometers are reliable assistants not only for private individuals, as well as large agro-industrial holdings. Conducting laboratory research is not always financially beneficial, and they also need time. If results are needed as quickly as possible, зручніше використовувати портативний «рефрактометр». Therefore, it is important to decide when choosing a model, which model will allow obtaining the required data in specific conditions. The following are presented on the market options:

• porative. These models are presented in 2 options: digital (with an LCD screen) and manual;
• partisans. Such devices continuously monitor the composition of liquids and are built into the conveyor system;
• llaboratory. They are used in processing plants, pharmaceutical enterprises, at medicine, on elevators, etc. d.

Regardless of species, the main function of all refractometers is to identify substances,their analysisand and determinedand physical and chemical indicators.

Refractometer product

Among the variety of models of refractometers, it is quite difficult to decide, which device is better to buy. In order to make the right choice, must analyze such nuances:

1. Features of samples. If they are different and in large numbers, then it is better to give preference to standard models. In the event of, when it is necessary to regularly analyze one product, refractometers of special modification should be purchased, which have additional scales.
2. housing. It can be metal or plastic. The first option is optimal in field conditions and for testing samples, which have a high temperature. Devices with a plastic case are more practical to use for working with non-hot samples, nand appropriate, acidic or salty environments.
3. Practicality of the model. The digital refractometer displays the measurement values ​​on the screen. Choosing manual, worth considering, that it must first be calibrated with distilled water, and only after that use, reading testimonytwo according to the scale Brix.

Buying refractometer, it is worth giving preference to verified sellers, which specialize in the sale of laboratory equipment of leading manufacturers and provide not only guarantees for goods, and also perform maintenance of devices (warranty and post-warranty). Cooperation with a responsible supplier of equipment, will help avoid problems in the future, because it will be possible to contact the service centerp for technical support, calibration assistance, settings, repair, etc. d.
