The ROSS line of Dual Shaft Mixers are robust and versatile systems, powerful enough to batch dispersions, suspensions, and emulsions with viscosities up to several hundred thousand centipoise. The custom-built ROSS FDA-3500 has a maximum working capacity of 13,248 liters, a two-zone stainless steel heating/cooling jacket, a four-inch pneumatic discharge valve and an explosion-proof load cell system rated for up to 20,000 lbs.
This multi-agitator system is equipped with independently controlled drives and is highly efficient at producing good turnover and imparting shear to a viscous batch. Powered by a 300 HP TEFC inverter duty motor, the High-Speed Disperser runs at tip speeds up to 5,000 feet per minute, inducing high shear forces while the 60 HP Three-Wing Helical Anchor Agitator feeds product towards the disperser blade and ensures that the mixture is constantly in motion. Teflon scrapers on the anchor wipe materials from the vessel wall, enhancing heat transfer from the jacket.

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
