Dust, oil and even powerful jets of water can’t trip up Ametek Brookfield’s TT-100 IECEx in-line viscometer. The instrument measures the same wide range of pressures, temperatures, viscosities, flow and shear rates as the company’s TT-100 viscometer, but can be used in hazardous locations worldwide that have IECEx, ATEX and North American explosion-proof certifications. Ametek notes that the device has better durability, more refined speed control with 16 selectable speeds up to 600 rpm and an expanded ambient temperature range of up to 55 degrees Celsius. It also has the motor and sensor components assembled in a single enclosure, the company adds. Web: www.brookfieldengineering.com
