Portable Refractometer

The refractometer is a laboratory device primarily used to measure the refractive index (RI) of samples. The refractive index is an indicator of the behavior of light on that sample. By knowing the refractive index, one can confirm the purity of a sample or measure its concentration. In cases of a sugar solution, the refractive index can be used to determine the sugar content. In scenarios like that in a production environment, a portable refractometer would be best suited because of its compact size and quick operation.

KEM’s portable refractometer: RA-130

Kyoto Electronics Manufacturing Co., Ltd. manufacture their own line of portable instruments in Japan, with the portable refractometer as a prime product. The automatic digital refractometer, called the RA-130 is a light-weight instrument that does not require any technical expertise to operate. You can either allow the sample to drip onto the prism or the prism of the portable instrument can be dipped into the sample beaker to measure refractive index. It is a microprocessor-controlled instrument with a bright, clutter-free LCD display. It is equipped with an infrared port for transmitting data to a computer.

RA-130 feature highlights

• Measurement range: RI - 1.3200 to 1.5000 & 0 to 85% Brix.

• In-built data storage of 1100 measurement results.

• Display measurement of refractive index, temperature compensated refractive index, percentage of Brix, HFCS42, HFCS55, and temperature in degree Celsius and degree Fahrenheit.

• Auto-inactivity detection switches the instrument off when it hasn’t been used for a long duration. This increases the life time of the batteries.

• Option of automatic data saving and automatic data output. Uses of portable refractometers To measure the:

• Concentration control on pharmaceutical and medical liquid samples. • Sucrose concentration in fruits juices.

• Sugar content in beverages and liquid seasoning.
