SCHEEN Engineering

Two Standard Methods in one Unit
The haze-gard dual objectively measures Total Transmittance and Transmission Haze according to two international specifications:
– ISO 13468 Compensation method
– ASTM D 1003 Non-compensated method

Precise and Reliable Readings – Any time
Total Transmittance and Transmission Haze in one unit
Reference beam, self-diagnosis and enclosed optics
guarantee accurate readings
Ready for measurement without warm-up time
Automatic and long-term calibration guarantee reliable
readings

Documentation of Measurement Data
The software easy-link transfers data to the PC for further data processing in Excel® (see page 20).

Exact positioning of films with a holder guided in a
precision track system.

Liquids are best measured using cuvettes and the cuvettetable.

The measurement of haze is used to determine abrasion resistance of transparent materials. The Taber Abrasion Holder facilitates positioning of the abraded area in the measurement beam.

	ASTM D 1003 Measurement conditions are different during calibration and actual measurement. During calibration, part of the light escapes through the open entrance port. While taking a measurement, the entrance port is covered with the sample. Thus, the amount of light in the sphere is increased by the light reflected at the sample surface. ISO 13468 Measurement conditions are kept equal during calibration and measurement due to an additional opening in the sphere. During calibration the sample is placed at the compen- sation port. For the actual measurement, the sample is changed to the entrance port. Thus, the socalled sphere efficiency is independent of the reflection properties of the sample. Note: Differences between the two methods can be approximately 2 % Total Transmittance on clear, glossy samples.
