What does the date code mean?
Most of City Technology’s sensors have an eight-digit serial number followed by a three-digit date code. The first two digits of the date code represent the month of despatch whilst the third digit represents the year. Certain sensors such as the Medical sensor range are marked differently and have either a 4 digit date code or a warranty expiration date. In the case of the 4-digit date code there are two numbers for the month followed by two for the year. In the case of the warranty expiration date, it is normally marked on boxes on the label. In this case the serial number can be used by City Technology to check the date of manufacture. For all sensors the serial number is used to trace the manufacturing data, test results and materials data for the sensor.
