Testing: The view on transmission, haze and clarity
The measurement of Total Transmittance and Transmission Haze is specified in two international test methods. ASTM D1003 requires illuminants C and A, using the non-compensated method. In contrast to this, ISO 13468 asks for readings taken under D65 with a compensated method. The new “haze-gard i” simultaneously displays results for both test methods.
High precision and reliability are guaranteed by using LED technology
Reference beam, self-diagnosis, automatic, long-term calibration and ten year warranty on the lamp life make the instrument operator friendly and safe for many years. The open design lets you work freely to analyse any sample size. Small and large samples can be quickly changed, positioned and measured without the influence of ambient light. A versatile sample holder for films and sheets is part of the standard delivery content and optional sample holders for taber abrasion test and cuvettes for liquids are available. To ensure flexibility the instrument can be set-up in a horizontal or vertical position.
A colour touch display with symbols to select menu functions and a measurement button make the instrument intuitive and easy to use for any task. For work management the measurement data can be statistically analysed directly or transferred to the software “smart-lab haze”. Thus, measurement data can be graphed in trend reports over time to evaluate process stability. Data transfer from the instrument to the PC can be performed via USB-cable, through direct LAN connection to a network or saved on a USB-stick.
