220V POL-200 Multi-Parameter Semi-Automatic Polarimeter Product Overview A polarimeter is an instrument for measuring the sample optical rotation. By measuring the rotation of the sample, the concentration, content and purity of the substance can be determined by analysis. Polarimeter is widely used in pharmaceutical, drug testing, sugar, food, spices, monosodium glutamate and chemical, petroleum and other industrial production, scientific research, teaching departments, for laboratory analysis or process quality control. Product Parameters Model: POL-200 voltage: 110V Range: 90/130Z Resolution: 0.005 Accuracy: 0.02/0.05Z Calibration Points: 1 to 3 points Light Source: LED and interference filter Tube Length: 50, 100 or 200mm Memory: 100 data sets Display: 5.6" TFT touch screen Package size: 24.4"*10.6"*18.5" (62CM*27CM*47CM) Net weight/Gross weight: 13LBS(6KG) / 16.5LBS(7.5KG) Product Features Advantages 1.Optical Lenses: The design of optical lenses is convenient to observe the internal situation at any time, and the circular plastic is convenient for eyes to observe and the design is more reasonable. 2.Test Tube: Test tube length can be flexibly set, optional test tube length or custom input, automatic calculation of standard measurement values of non-standard test tubes. 3.TFT Touch Screen: Multi-parameter semi-automatic polarimeter with 5.6" TFT touch screen. Touch button design, just touch the screen to start the measurement process, simple operation, easy to use. ? 4.Non-slip Foot Mat: There are four rubber support pads at the bottom, which can play a good support, anti-slip, waterproof role, so that the instrument work more stable and safe. 5.Heat Dissipation Hole: The machine is designed with a heat dissipation hole, timely heat dissipation, reduce the motor temperature, extend the service life. 6.Fuse: Once the current is too large fuse will be blown, protect the internal circuit of the machine; If blown, just replace the fuse can be used normally. It will be safer and extend the service life. ? Functional Characteristics: • 4 measurement functions are available, including rotation, specific rotation, concentration and International Sugar Scale. • Long life LED to avoid the 200-hour limit of traditional light sources. • Automatic zeroing system, one click to restore the instrument to optical zero. • Automatic temperature compensation for instant conversion of measured values to specific curl values. • 1 to 3 point calibration ensures measurement accuracy over the full range. • Automatic information prompts to help users understand the currently available steps. • 100 sets of data storage, automatic date/time marking and sample name input. • Reset function to automatically restore the meter to factory default Settings. Working Principle The light emitted from the light source becomes plane polarized light through the condenser and filter and the polarizing mirror, and the three share vision field of view is generated at the half-wave plate. Three conditions can be observed through the polarizer and the eyepiece group - A. Field of view greater than/less than zero; B. Field of view zero; C. Field of view less than/more than zero). Rotate the polarizer, only at zero, the brightness of the three parts of the field of view is consistent. When put into the test tube containing the tested solution, because the solution has optical rotation, the plane polarized light rotates an Angle, and the zero degree field of view changes. By turning the deflector to a certain Angle, the field of view with the same brightness can appear again. This Angle is the optical rotation of the solution, and its value can be read from the dial through a magnifying glass. After measuring the optical rotation of the solution, the specific rotation of the substance can be found. Based on the magnitude of specific rotation, the purity and skin content of the substance can be determined. Product Presentation Details ?
