The sample cells can also be used for the measurement of poisonous and toxic samples with minimum exposure to the sample. The refractive index of a given sample varies with wavelength for all materials. Invest in a refractometer for measuring your salinity accurately. As light passes through the liquid from the air it will slow down and create a ‘bending’ illusion, the severity of the ‘bend’ will depend on the amount of substance dissolved in the liquid. Il suffit alors de faire une lecture directe. eur-lex.europa.eu. Retirer le capuchon de la vis d’alignement. Réfractomètre Analyse de boissons Tous les types de produit ... A calibration is traceable when the performed measurement is directly linked to the respective national standard by a consistent measurement chain. [2] There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases. Voici les spécifications pour le HHTEC 4-In-1 Réfractomètre Antigel éthylène Glycol: ... El equipo se compró para ver el punto de congelación del agua con anticongelante en un circuito de refrigeración de agua fría. In the automobile industry, a refractometer is used to measure the coolant concentration. Check to make sure that 500ml water bottles and 3g sugar packets were used. Refermez le couvercle et appuyez légèrement dessus. Suitable for following refractometers: RBR5-ATC, RBR10-ATC and RBR20-ATC.

This eliminates human error and assures a high sample throughput. Temperature has a very important influence on the refractive index measurement. Once an automatic refractometer is equipped with a flow cell, the sample can either be filled by means of a syringe or by using a peristaltic pump. Vous trouverez ici les notices d'utilisation, les prospectus et bien d'autres documents relatifs à votre produit KERN, y compris pour les anciens modèles qui ne sont plus commercialisés. In drug diagnostics, a refractometer is used to measure the specific gravity of human urine. dispersion), the measurement is normally taken at the wavelength of the sodium line D-line (NaD) of ~589 nm. Réfractomètre industriel pour des applications pharmaceutiques. In the machine industry, a refractometer is used to measure the amount of coolant concentrate that has been added to the water-based coolant for the machining process. L'icône indique que le mode ou le menu de calibration est actif . High accuracy over a wide measuring range. follow the calibration steps a sec-ond time. Apera Instruments AI1114 pH Calibration Solution Kit (7.00, 4.00), 16 oz. There are several subtly-different designs for controlling the temperature; but there are some key factors common to all, such as high-precision temperature sensors and Peltier devices to control the temperature of the sample and the prism. Un réfractomètre mesure la «flexion» de la lumière lorsqu'elle traverse un matériau. Brix refractometers are often used by hobbyists for making preserves including jams, marmalades and honey. Interpréter la lecture du réfractomètre. $8.99 Next page. K-Patents Process Refractometer PR-23 meets the pharmaceutical industry standards and guidelines. The high accuracy of up to ± 0.03 °C is achieved by precise internal Peltier temperature control. 701814 Presentation Specifications Calibration is becoming an increasingly important part of quality assurance in terms of meeting standards and regulations. 4.7 out of 5 stars 384. There are different types of sample cells available, ranging from a flow cell for a few microliters to sample cells with a filling funnel for fast sample exchange without cleaning the measuring prism in between. Check to make sure that 5 capfuls of water were removed before adding sugar. Kern & Sohn GmbH. Un prisme, équivalent au prisme inférieur d’un réfractomètre d’Abbe classique est plongé dans le liquide à tester. Contactez-nous pour plus d’informations ou demander un devis.
