Key Features
• Single touch operation
• Automatic control of the movement
of fluid until the upper mark.
• Automatic sensing of the upper
and lower marks ensuring error free
repeatable measurement of the time
taken for the liquid coloumn to fall.
• Automatic measurement of
temperature during the test using a
Pt 100 probe.
• Automatic correction of formula for
calculation of the blaine value per
applicable standards (ASTM/EN) with
variation in temperature.
• Facility to configure and monitor
various cement types.
• Timing accuracy upto 200mSec.
• Up to 10K values may be stored
in the internal memory (first time this
has to be done by connecting a computer
/ can be done at the factory on
request)
• Easy and tamper proof calibration
using a lockable ball valve
