The Rudolph J57-VT High Accuracy and J57 Wide Range refractometers are designed to meet the unique needs of food quality testing where the automatic refractometer . Standard configuration includes sample Temperature Control . I have seen something similar, and I agree. You have to be sure the temp is within the range the ATC can handle. The refractometer usually includes a spec for the temperature range over which ATC will compensate - 10-30C/50-86F is typical, so 35F is too cold for the correction to work, which is why you need to warm it up to get an accurate reading.Digital handheld refractometers, on the other hand, automatically measure samples using a high-resolution optical sensor, which delivers remarkably accurate results. Due to their simplicity and operator independence, they provide greater repeatability and ease of use.

From light to dark, from alkaline to acidic, from low to high viscosity – our refractometers can measure almost all samples. The devices determine the refractive index of liquid or solid substances, from which their identity and quality as well as the concentration in binary (mixture of two different components) or quasi-binary mixtures can . The refractive index is a dimensionless number that indicates how light is bent or refracted as it passes through a substance. It is a fundamental property of materials that can be influenced by factors such as temperature, pressure, and composition. Refractometers typically consist of a prism or a sample well, a light source, and a viewing system. Abbe Refractometers, or Laboratory Refractometers, are laboratory-grade instruments known for their high precision, making them suitable for detailed analysis. They are commonly used in research laboratories to measure the refractive index of liquids and solids, in the pharmaceutical industry to determine drug formulation concentrations, and in .The RFM900-T Series of high precision Peltier temperature controlled benchtop refractometers, featuring a wide measuring range up to 1.70 RI and new 7” touchscreen user interface, are ideally suited for use in applications within the chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as in academic research.

The experimental results show that the proposed sensor exhibits a high temperature sensitivity of 7.61 nm/∘C with good linearity. This work provides a new strategy for the fiber-optic sensing field.
The refractometers discussed herein benefit from the following desirable features: (i) shift the highest sensitivity from high SRI value (glass guiding media around 1.45) to low SRI value (water or water-based solutions close to 1.33), (ii) measure power rather than wavelength for cost-effective interrogation, (iii) the self-referenced core .Many modern refractometers have on-board Temperature correction capabilities which are a built-in mathematical scale that are designed to compensate for varying measurement temperatures. Temperature Control is much different and actual heats or cools a sample to a user defined temperature – Example 20C.Refractometers measure the change in the angle of light as it enters a transparent liquid or solid substance. Refractometers are commonly used to identify a material, determine its purity, or indicate the amount of a dissolved substance that it contains. . a wide temperature control range from 10 to 65°C, and pre-programmed concentration .High Accuracy Laboratory Refractometer – Model J457 Our Most Advanced Model. Ideal for very demanding Pharmaceutical, Analytical, and Chemical Labs. . More accurate and reproducible than 4 decimal place wide range chemical refractometers. Dual Electronic temperature control from the top as well as bottom of the sample well.

Buy Agatige Refractometer, 0-90% Brix Meter Refractometer Handheld Sugar Refractometer High Accurate Brix Measurement Meter with ATC, Wine Extractor Tester Machine for Fruit, Beverages&Juice, Honey: Refractometers - Amazon.com FREE .The refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v.It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. In simple words, the index of refraction describes how fast a light .
High-precision temperature control stabilizes the temperature of both the sample and the measuring prism, and is combined with highly accurate temperature sensors. How refractometers provide highly accurate results by considering all relevant factors is summarized in this video: Figure 9: Refractive index (λ = 589.3nm) of water at temperature .
