The 301 densitometer has been in production for many years.
Because of design changes over the years it has made it impossible
to service units with a serial number below 5480. (no recert or repair)
***These units are over 30 years old.
***This doesn't apply to the 301X (220v) units which have a separate serial number system.
****Service pricing and Discontinuation are subject to change at any time. Contact Customer Service
for current information and to get an RMA before sending in.
