The abbeder refractometer is an instrument capable of determining transparent, translucent liquid, or solid refractive index ND and a flat dispersion ND-NC (which is mainly in which the transparent liquid is mainly).
Product Description: Digital melting instrument is completely "humanized" design concept, using photoelectric automatic detection, dot matrix image liquid crystal display, digital keyboard input, one sample per measurement, can measure the average of 3 automatic evaluation melting point, And has a function of initial melting, finish automatic display, melting curve automatic recording. The temperature system applies a high linearity of platinum resistance to detect the detection element, using PID adjustment technology, improves the accuracy and reliability of the melting point, and realizes a fast "start temperature" setting and eight gear options with integrated electronic circuitry. Linear "heating rate" automatic control. The instrument establishes a communication, saving or printing a graph via USB and PC, and the instrument can directly connect the micro printer with the RS232, print the graph. The instrument uses a pharmaceutical description of the capillary as a sample tube Melting point measurement range: room temperature - 320 ° C "Start Temperature" set time: 50 ° C-320 ° C is not more than 4min 320 ° C -50 ° C no greater than 6 min "Starting Temperature" Setting Named Error: ± 0.4 ° C Temperature digital minimum display: 0.1 ° C Linear heating rate: 0.2 ° C / min, 0.5 ° C / min, 1 ° C / min, 1.5 ° C / min, 2 ° C / min, 3 ° C / min, 4 ° C / min, 5 ° C / min eight files Linear heating rate error: 10% of the set value Figure error: less than 200 ° C In the range: ± 0.4 ° C 200 ° C-300 ° C In the range: ± 0.7 ° C Demonstration repeatability: When the temperature increase rate is 1.0 ° C / min, 0.3 ° C Standard capillary size: outer diameter φ1.4mm inner diameter φ1.0mm, length 80mm Sample fill height: ≥ 3mm Power: 220V ± 22V, 100W, 50Hz Instrument size: 365mm x 290mm x176mm Net weight: 10kg
