Butyro Refractometer, Certificate : ISO9001:2008

The Butyro Refractometer is a specialized optical instrument designed for the rapid and accurate determination of the refractive index of fats, oils, and butter, especially in dairy laboratories. Commonly used to assess the purity and quality of ghee and butter, this analog device operates based on light refraction principles and provides direct readings on a calibrated scale.

It features a robust metallic or aluminum body, a precision-ground glass prism, and a high-quality optical system enclosed in a dust-proof casing. The instrument typically offers a refractive index range of 1.42 to 1.47, with a least count of 0.0001, ensuring fine resolution and accuracy in measurement. It is equipped with a thermometer well and circulating water jacket for maintaining the prism temperature at the standard 40°C, which is critical for consistent results.

The Butyro Refractometer is widely used in dairy plants, food inspection agencies, and quality control labs, offering reliable performance, simple operation, and minimal maintenance. Its manual design allows dependable field and bench use without the need for power or complex calibration.
