Penetrometer Needle for Bituminous materials. Standard hardened stainless steel needle, 40-45mm exposed needle length. Wt. 2.5g. ASTM D5; AASHTO T49, IP49; ASA Std., A37.1; Fed Spec. SS.R. 406C, Meth. 214.01.Catalog No.: A1580-1 | A1580-2
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...Catalog No.: A1383-2
Constant Temperature Semi-Automatic Ductility Testing Machine designed explicitly for testing the ductility and elastic recovery of bituminous materials. Features a 6" LCD touch screen control panel. This integrated touch screen allows the user to choose between the ductility or recovery test methods. The custom menu allows for the input of desired speed and time parameters. During testing, the distance traveled by the specimen is displayed and a simple touch of the screen can record the distance traveled upon breakage of the briquet. A motor jogging feature permits locking of the sample...Catalog No.: A1380-1 | A1380-2 | A1380-3 | A1380-4 | A1380-5
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...Catalog No.: A1570-1 | A1570-2
Designed for ASTM penetration tests on petroleum products and for consistency tests on a wide range of food products, cosmetics, pastes and other solid to semisolid products. Precision machined and assembled to exacting specifications, and ruggedly constructed to insure long service life in both laboratory and field applications. Features a full penetration range of 0-62.0mm with 1/10mm subdivisions (0-620 penetration scale). Accommodates cones and needles to perform all of the ASTM tests on lubricating greases, asphalts, petroleum waxes and petrolatums. Compact design facilitates...Catalog No.: A1573-1 | A1573-2 | A1573-3 | A1573-4 | A1573-5
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).

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...Catalog No.: A1574-1 | A1574-2
KOEHLER Breaking Point of Bitumen Apparatus. Determines the breaking point of solid and semi-solid bitumens. A thin steel plaque is coated with the sample and flexed in a bending apparatus at descending temperatures until cracks appear in the sample coating. Consists of two concentric borosilicate glass tubes with movable steel plate holders. A cone-and-peg mechanism moves the inner tube up and down relative to the outer tube, which varies the distance between the plate holders, causing the stainless steel test plate to be flexed. The inner tube accommodates a test thermometer. Supplied...Catalog No.: A5010-1 | A5010-2
Ring and ball method softening point apparatus used for single determinations, asphalts, pitches, tars and most resins. Includes burner, beaker, support stand, 1 ring, wire gauze with ceramic center, thermometer clamp, 1 shouldered ring and stem with hardened steel ball. Order Thermometer separately. Meets ASTM D36, E28; AASHTO T53.Catalog No.: A1620-1 | A1620-2 | A1620-4 | A1620-5 | A1620-6 | T4180-113C | T4180-113F |
Automatic instrument for precision penetration measurements of bituminous materials, cement, petrolatum, waxes, food, cosmetic, and pharmaceutical products.
