Multi-item chemical analyzer
专利汇可以提供Multi-item chemical analyzer专利检索，专利查询，专利分析的服务。并且PURPOSE:To make the device small-sized and light, to simplify the circuit for calibration and to reduce the adjustment time by using a CCD of a small capacity as a photodetector. CONSTITUTION:The light ray from the light source 1 is led to the flow cell 4 by the optical fiber 3 through the lens 2 and is applied to the tip end 12a of the fiber through the condenser 6 after it passes through the flow cell 4 and optical filter 5. The incident ray is transmitted to the columnwise terminals 12 of the optical fiber and is applied to the condenser 13. The collected light ray reaches the light receiver of respective corresponding parts of the CCD14. The CCD14 provides current corresponding to the quantity of light ray received by the light receiver in turn. The output current is converted into voltage by the I/V converter 17, and is done into a logarithmic value by the Log converter 18 to feed itself to the AD converter 19. The AD converter 19 is controlled by the CPU20, and converts the input signal into a digital value at the timing corresponding to the transfer order of the CCD14. The digital output V0 is provided for the desired measurement.，下面是Multi-item chemical analyzer专利的具体信息内容。
