| Characteristics | 
 | 
 The instrument uses the LED as the optical source; single optical channel; plugging mode filter; digital displaying . Because of simple operation, convenient maintenance and stable performance, it can be applied to any need of fluorescence analysis. It also can be transformed between concentration and fluorescence intensity . The result can be output by RS232 interface.  |
