PTRP100 Portable Refractometer, also known as the Portable Brix Meter, is an ideal choice for measuring the Brix value and refractive index of liquids with high accuracy.
The portable refractometer is compact and lightweight, suitable for use in various industries as well as in research, chemical, and analytical laboratories. The portable refractometer allows quick and simultaneous measurement of the refractive index (nD) and Brix value (°Bx).
It can be charged via a USB port or mobile charger and supports direct connection to a computer or printer. The device also features automatic temperature compensation to improve concentration measurement accuracy. The prism is made of sapphire, providing high resistance to corrosive materials and elevated temperatures.
PTRP100 Portable Refractometer can measure sample concentration in the range of 0 to 100 Brix and refractive index from 1.33 to 1.54.
This model can measure samples with a temperature of up to 90°C and includes temperature compensation capability for the range of 5 to 50°C. The Portable Refractometer is covered by a one-year warranty and ten years of after-sales service.
A digital refractometer or digital Brix meter works by using an LED light source positioned above a prism to illuminate the sample. The refracted light is then measured by a sensor, allowing the device to determine the angle of refraction.
Since the measurement depends on temperature, the device applies temperature correction using specific algorithms and converts the data into refractive index or other related parameters.
Compared with similar instruments, digital refractometers offer advantages such as ease of use, automatic temperature correction, and adjustable measurement ranges. These devices are also available in smaller sizes as portable refractometers.
PTRP100 Portable Refractometer is also suitable for coffee analysis. A coffee refractometer is a scientific instrument used to measure the concentration of coffee solutions.
It measures the refraction of light passing through the brewed coffee and determines the amount of Total Dissolved Solids (TDS) present in the beverage.
The process of using a coffee refractometer generally includes the following steps:
Calibration: Calibrate the device with distilled water or a special calibration solution to ensure accurate results.
Sampling: Take a small amount of brewed coffee and place it on the prism surface.
Measurement: Turn on the device and read the TDS value displayed on the screen.
By using this tool, you can ensure that every cup of coffee served meets your desired standards and delivers the best possible taste and aroma.
