KRFL - 1A Ultra - Weak Chemiluminescence / Bioluminescence Detector

KRFL - 1A Ultra - weak Chemiluminescence/Bioluminescence Detector

Product Introduction

The KRFL - 1A ultra - weak chemiluminescence/bioluminescence detector is a measuring instrument specifically designed for measuring weak luminescence signals. The instrument has two measurement modes, namely energy measurement and charge integration measurement, and features a very wide dynamic measurement range. It is suitable for various analytical devices equipped with photodetectors (such as photomultiplier tubes, phototubes, photodiodes, etc.), such as chemiluminescence analysis, fluorescence analysis, and flame molecular (atomic) emission spectroscopy analysis. The instrument is internally equipped with a high - precision negative high - voltage power supply, a high - precision signal amplification and signal processing system, and a VFD digital display. The negative high - voltage power supply is dedicated to the photomultiplier tube, the signal amplifier is used to amplify and filter the signal after photoelectric conversion, the signal processing system processes the measured signal and transmits it to the system computer for analysis, and the VFD display is used to show various measurement parameters and signal values. The IFFS - A multi - functional chemical spectrophotometric detector equipped with this instrument, together with the main unit, constitutes an ultra - weak chemiluminescence/bioluminescence instrument.
