What is the measurement range of the portable refractometers?
The range of refractive index the portable refractometers can measure varies from 1.32 to 1.65, depending on the model.

Can the portable refractometers be used to measure concentration?
Yes, a sample’s refractive index value can be automatically converted into concentration values for a large number of factory-programmed substances. You can also program special substances as required. Sample naming ensures perfect traceability of results.

How many measurements the portable refractometers store?
The portable refractometers can store up to 1,100 results in the built-in memory.

How often should I calibrate the portable refractometer?
To calibrate the instrument, measure a certified standard liquid and compare the result to the reference value indicated in the calibration certificate of the standard. The physical properties (refractive index, viscosity) of the liquid density standards should be similar to those of the samples. The frequency of calibrations with certified liquid refractive index standards depends on your requirements and judgement. Recommendation: 1 to 2 calibrations per year.

How do the portable refractometers transport data?
The portable refractometers utilize infrared for data transfer to a PC or printer (IrDA or RS232C protocol).
