How can I decode the serial number of a QBD1200 TOC analyzer?
Summary
Serial numbers for TOC QBD1200 analyzer
Answer
The serial number of a QBD1200 TOC analyzer can be decoded to tell you when it was manufactured and if it was sold by Beckman or Hach:
The first two numbers are the year of manufacture. The next three digits are the chronological day of the year it was built. Example 16115 would be 2016 on the 115 th day of the year.
Next the serial number will contain two letters, HC is Hach Company and BC is Beckman Coulter.
The next 5 digits will be sequential number of analyzers produced. Example 00110 is 110 th unit produced that year.

Full example 17030HC00005:  this unit was sold by Hach Company on January 30th, 2017 and was the 5th unit built that year.
