7. Metrology - Draft Protection Ring
(Secura Only)
•^ User Problem
Users of Secura need to have quick and
reliable results. Very often they need to
work in laminar flow for personal safety
while every balance is sensitive against
draft and wind e.g. in an fume hood.
It is a typical task to do dosing of smallest
amounts, which is an increased difficult
task under the fume hood.
Usually the user needs to close the draft
shield of an Analytical balance after he has
changed the weight and need to wait for
the stabilization of the balance. This is very
time consuming. If the door is left open
the balance will not stabilize or activated
programmed filter algorithm will make
the balance slow as a result make the
balance slow to respond to environmental
conditions.
Both is a problem for the user if he needs
to dose small amounts in laminar flow like
an exhaust or fume hood.
• Sartorius Solution
Sartorius developed the draft protection
ring (Ring around load plate) and opti-
mized it for maximum draft protection.
This enables the balance to stabilize faster
and enable the user to dose smallest
amounts under a fume hood much easier.
For secure and final measurement the
Analytic draft shield need to be closed
completely.
A typical improvement of 30 digits with
open draft shield is possible, depending on
the situation on site.
