Automatic Polarimeter SWP-3 (±89°, temp. control)
SWP-3 automatic polarimeter adopts the LED as the light source
Touch-screen display operation
Measurement: ±89° (Optical rotation)
Temperature control 15°C~30°C
USB and RS232 interface
- LED as the light source to avoid frequent replacement of the sodium lamp.
- Temperature control device in the Instrument has the functions of heating and cooling, so temperature controlled measurement to the optical rotation of a sample can be achieved with a temperature controlled test tube.
- Large touch-screen LCD display of the Instrument provides a HMI with menu operation mode, simple and visual, stable and reliable.
