Figure 1: Haze measurement
Commercial hazemeters are typically used for this testing, but ASTM D 1003 also allows the use of a spectrophotometer, provided it meets the procedure requirements. ExxonMobii uses the SKY-Gardner XL-211 Haze-gard and Haze-gard plus hazemeters consistent with ASTM guidelines. The hazemeter may also be set up to measure and display light transmission.
