On-line Hazemeter

The TM-100M is designed to measure the transmittance of the films and glass plates being in a manufacturing process. The instrument provides for the absolute transmittance value measurement value (reference 1) and the measured value control (reference 2).


  1. This value is obtained by calibration to indicate 100% as the transmittance of air while no specimens are placed in the light path. The transmittance of the samples are obtained when they are placed in the path
  2. A specimen for reference is put in the light path and memory knob is adjusted to indicate zero(0) in the center of the recorder for a long-term memory. LED light switches ON when the transmittance of the samples are beyond the allowance of the reference value.


  • Managing the transmittance of plastic films.
  • Managing the transmittance of plastic sheets.
  • Measuring the transmittance of polarizing films.
  • Measuring the transmittance of sheet glass.
