This instrument level is 0.02 grade.
The sodium lamp was replaced by a light-emitting diode (LED) and a filter, and the average service life of the light source is more
than 20000 hours. This instrument needs not to be warmed up before startup. The optical
rotation, specific rotation, concentration and sugar content of the samples may be
automatically measured (1 to 6 times dependent on your selection), and then the average
as well as the root mean square (RMS) may be worked out automatically. An insulation
design was adopted for the sample well, so that the influence of temperature rise on the
measurement may be reduced. There is a function for temperature display, which is
convenient for the users. Samples of deep color may be measured too.
