Automatic Blaine Apparatus – Model TO-391

The Automatic Blaine Apparatus from Tinius Olsen is an automated version of Blaine apparatus and follows global standards. It is used to establish the fineness of cement using the Blaine air-permeability apparatus, in terms of definite surface expressed as total surface area in square meters per kilogram, or square centimeters per gram, of cement.

Key Features

  • Easy, tamper-proof calibration using a lockable ball valve
  • Single-touch operation
  • Automatic control of fluid movement
  • Automatic measurement of temperature during the test
  • Automatic sensing to ensure error-free, repeatable, measurements
  • Automatic formula correction for the calculation of the Blaine value with variation in temperature (as per ASTM and EN)
  • Facility to configure and monitor a range of cement types
  • Storage of up to 10,000 data points
  • Timing accuracy up to 200 mSec
