产品描述
Characteristic：
Light emitting diode as the light source using SGW -3 automatic polarimeter, to avoid the frequent replacement of sodium lamp. The temperature control device within the instrument has the function of heating and cooling, temperature control can be used if the tube type temperature measurement of a sample rotation. Large screen LCD display on the instrument provides man-machine dialogue menu operation, simple, stable and reliable.
