GLS
Portable gloss measurement for all surface finishes

The PosiTector GLS measures GU (gloss units) and percent reflectance. Innovative technology and factory calibration in the PosiTector GLS mean that it arrives ready-to-measure – usually, there is no need to perform a calibration adjustment. If the probe is resting in the included protective base plate and the Power-On Cal feature is enabled, the probe will automatically perform a check and calibration using the certified gloss standard (tile) incorporated in the base plate.

Conforms to ASTM C584/D523/D4039, ISO 2813/7668, JIS Z 8741, AS/NZS 1580.602.2

Select from 3 probe models:GLS 60 – suitable for most gloss applications, preferred angle for semi-gloss

GLS 20/60 – suitable for high- to semi-gloss applications. Calculates Haze (Haze Index)

GLS 20/60/85 – suitable for high-, semi-, and matte- gloss applications and also calculates Haze (Haze Index)
