We herewith inform about the change of densitometers factory calibration to glass tubes of 16 mm outer diameter.
The change is connected with two facts:
1) majority of users using densitometers with A-16 adapters (i.e. for 16 mm diameter tubes),
2) discontinuation of the standard used for factory calibration for 18 mm tubes.
The cat.numbers for ordering will remain the same while A-16 adapter will be included in standard delivery set and the pricing are adjusted accordingly (with discounted A-16 price added to the DEN-1, DEN-1B price).
