The OHSP250I miniature spectrometer is a new generation online testing instrument. -The integration of micro spectrometer technology and microcomputer technology has brought the previously bulky testing instruments from the laboratory to the production line, achieving online analysis of light color parameters. The test results are directly output through RS485 or USB interfaces, and the communication protocol is open and compliant with Modbus communication protocol.
