RFL-200 Ultra-weak chemiluminescence/bioluminescence detector

RFL-200 Ultra-weak chemiluminescence/bioluminescence detector 

RFL—200 ultra-weak chemiluminescence/bioluminescence testing instrument is a multi-functional ultra weak luminescence detector. Its multi-functional detector can be equipped with flow or static liquid detecting device to meet the different requirements of the tests. The instrument has wide dynamic test range and two measurement methods which include energy measurement and charge integration test. The instrument is equipped with high accuracy negative high voltage power source and high accuracy signal amplifying and processing system and VFD digital display.

Besides, the detector is provided with automatic control signal.
