For a project we needed to read out our PC-222 multimeter. It supports RS-232, but the protocol is not documented at all and the software is proprietary. After a little research on the web, we found some information in a comment on Amazon. With this and a little trial–and–error we found out how it works.
ICP–OES is a common technique in analytical chemistry, which is characterized by simplicity, simultaneous multi-elemental determination capability, high sensitivity, linear dynamic range, low detection limits, and good precision . It seems to be the perfect method for element analysis (esp. metals). However, sometimes it can fool the user.
