BYK-Gardner GmbH, Geretsried, Germany, is introducing a new haze meter to simultaneously measure total transmission, haze and clarity according to ASTM and ISO test methods: the haze-gard i. The measurement of Total Transmit-tance 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.
