KOEHLER K80050 Standard Ductility Machine, Semi-Automatic. 115V-240V, 50-60hz

The KOEHLER K80050 Semi-Automatic Standard Ductility Machine is a three-speed apparatus which pulls briquets of bituminous materials apart at a uniform speed while immersing them in water. As many as three specimens at a time can be tested at speeds of 0.25, 1 or 5cm per minute. A synchronous direct motor drive unit maintains constant speed without vibration. Drive unit rides on a bronze lead screw mounted above the water level to prevent agitation of water and premature rupture of specimens. A traveling pointer indicates the position of the carriage against a linear centimeter scale on...

KOEHLER Digital Penetrometer. ALL MODELS

KOEHLER Digital Penetrometer is a microprocessor-based penetrometer that tests the consistency of lubricating grease, petroleum waxes, bitumens, pastes, creams and other solid to semi-solid products. It provides a full range of measurement and reporting options and operation is simplified by four user programmable presets that facilitate lowering the penetrator tip to the sample surface. The detachable machine base provides a large platform to accommodate a wide range of sample containers and constant temperature cylinders. It removes easily to permit the head assembly to be reversed (for...

KOEHLER Softening Point Apparatus, ASTM D36

KOEHLER Softening Point Apparatus, ASTM D36. The sample is cast in shouldered rings and heated at a controlled rate under the weight of a steel ball. The softening point is the temperature at which the bitumen disks soften and sag downward a specified distance. Consists of 800mL beaker, 2 standard balls, shouldered rings, ball centering guides, ring holder, bottom plate and beaker cover with support rods. Order thermometer and heater separately. Conforms to the specifications of: ASTM D36, E28; AASHTO T53; IP 58, 198; NF T 66-008. Shipping Weight: 4 lbs (1.8kg).

KOEHLER Penetrometer Bath. ALL MODELS

Constant temperature water bath for conditioning samples prior to a penetration test. Full visibility bath has a large shelf to accommodate a wide range of sample containers, including all containers used in ASTM tests. Sample containers can be left in the bath during the penetration test if required. The base of the Koehler manual penetrometer can be placed directly on the shelf of the bath, or the head assembly of the digital automatic model can be reversed to overhang the bath. Temperature Range: Ambient to 70°C. Microprocessor digital temperature control maintains bath liquid...
