BELSORP MR1 BET Surface Area Analyzer

BELSORP MR1 BET Surface Area Analyzer

Microtrac MRB | Surface Area and Pore Size, Polarimeters

The BELSORP MR1 is designed for rapid and convenient BET single-point measurement.

Highly efficient measurement

Simultaneous pre-treatment and measurement improve process efficiency.
BET single-point measurement of specific surface area possible in approx. 15 mins (including calibration).

Highly accurate measurement

  • AUTO-ZERO function is equipped with a highly sensitive thermal conductivity detector (TCD)
  • High accuracy, high sensitivity, high reproducibility
  • A dedicated calibration valve enables simple and stable calibration measurements
  • Automatic measurement of temperature and pressure for accurate calibration.

Easy Operability

  • Easy handling thanks to an automatic Dewar elevator and a cooling fan
  • User-friendly touch panel
  • Measurement results and trend data can be saved to a USB memory drive
  • Compact design without external PC
