| The Bending Beam Rheometer （BBR） Model:GSF3-HM-59 | Cat.No: |
| The Bending Beam Rheometer （BBR） supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn measures flexural creep stiffness of asphalt binder at low temperatures （ambient to -40°C）. A constant load is applied to the center of a small asphalt beam specimen, and the deflection of the beam is measured and recorded. Tests are quickly and easily set up and parameters input through the included PC with pre-installed software. Load, displacement, and bath temperature are displayed and displacement, loading, and temperature graphs are displayed throughout the test cycle. Stiffness is calculated at the lowest temperature anticipated. HM-59 BBR is constructed of stainless steel and durable, high-strength polymer components. The unit uses an air bearing system （50 PSIG minimum, clean, dry compressed air source required） to assure reliable loading with accurate and repeatable results. A linear variable displacement transducer （LVDT） with a range of 6.35mm and accuracy to ±2?m measures deflection. The temperature-compensating 500g load cell with mechanical overload protection ensures accurate load results. Safe, rapid cooling of the test fluid （Ethylene Glycol/Water/Methanol） to -40°C （-40°F） is provided by the mechanical refrigeration system. Process temperature is controlled and monitored by two independent platinum RTD temperature transducers to maintain temperature stability. The HM-59 includes a Computer with pre-loaded control, acquisition, and analysis software, five aluminum specimen Molds with mylar strips, a Calibration Kit with required weights, and Confidence Beam. Calibrated test weights and a certified LVDT NIST-traceable standard are provided with each system. The easy-to-use software allows daily verification and periodic calibration of load cell, LVDT, and RTD transducers. Est. Ship Wt.: 250lbs （115kg）. Adequate compressed air source must be supplied by user. Purpose:Research | Model:GSF3-HM-59 |

| Gilson offers five sizes supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn Gilson offers five sizes of Asphalt Institute Viscometers to determine viscosity of highly viscous materials such as bitumen at 140°F （60°C）. The user measures elapsed time for a fixed volume of liquid to be drawn by vacuum through the graduated capillary tube. Time is multiplied by the viscometer constant to obtain absolute viscosity. Measurement requires a minimum sample size of 3ml and a bath depth of 7in （180mm）. Certificate of calibration is supplied with each viscometer. Neoprene rubber holders to fit a 2in （51mm） diameter hole are ordered separay as PTA-100. Inquire if fixed metal holders preferred. Also see stopwatches and thermometers listed elsewhere. Est.
