FOR VOLUMETRIC INSTRUMENTS OF PLASTIC (CLASS A) AND PISTON-OPERATED VOLUMETRIC INSTRUMENTS
Starting January 1, 2015 VITLAB will change the mark on volumetric instruments from “H” to “DE-M”. A complete conversion will take place over 2015. Since our volumetric instruments have historically been sold with a simple manufacturer’s test and not with official calibration, our production and testing methodology will remain the same. As always , we will comply with applicable standards. As in the past, no regular official calibration during the usage phase is planned . The marks “H” and “DE-M” can be considered equivalent and both are valid for an unlimited period.
