DeFelsko’s PosiTector GLS Gloss Meter brings gloss, reflectance, and haze measurement to the versatile PosiTector platform.
The new meter is just one of several interchangeable probes that fit the PosiTector gage body, making it one of the most flexible instruments in a coating professional’s toolbox.
Users may select up to three measurement angles to suit any application. Readings are then saved into memory and can be transferred to PosiSoft Software to quickly archive data and generate professional reports.
Three gloss probe models are available: The PosiTector GLS 60, which is suitable for most gloss applications and is the preferred angle for semi-gloss; the PosiTector GLS 20/60, recommended for high- to semi-gloss applications; and the PosiTector GLS 20/60/85 is suitable for all gloss applications.
Additionally, both the PosiTector GLS 20/60 and 20/60/85 calculates Haze (Haze Index). The gloss probes feature Automatic Diagnosis and Calibration upon power-on using the protective base plate with integrated calibration standard (tile). Users can store and manage up to 99 different calibration standards (tiles) for quick calibration adjustments. Measurement speeds reach 60+ readings per minute, and Advanced models include two powerful Scan Modes for quantifying large surfaces.

Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.
As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.
The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
