Environmental Conditions
The BBR3 is designed for use in an industry/laboratory setting in an indoor and dry environment. The base unit
should be placed on a clean, stable work surface with the connecting mechanical refrigeration unit nearby. The
mechanical refrigeration unit should be placed 6 inches above the floor and in an area that will not constitute a
tripping hazard.
Load Frame
The load frame is an independent three-point loading device designed to apply a load of up to 4000 mN. The load
frame may be operated in the supplied fluid bath, or it may be used in ambient conditions. The load frame is designed
with space-saving design, rigid construction, and corrosion resistance.
The load frame is constructed of stainless steel plates and durable high-strength PVC uprights that are designed
to be dimensionally stable and provide accurate force control. The load frame consists of an integral free-floating
loading shaft within an air bearing to permit specimen loads in the range of 0 to 4000 mN. The air bearing also
provides reliable and rapid loading with an accuracy of ±5 mN.
