The apparatus consists of a constant temperature bath capable to work in the range from -10 to 40 °C (thanks to a built-in cooling compressor) with an electrically powered tractor that pulls apart at a determined speed the two ends of two briquet specimens: the elongation is measured by means of a pointer on the tractor and a graduated scale fixed to the cover.

• Acrylic hinged cover: it helps to maintain a constant temperature in the bath providing a clear view of the inside.
• Traction carriage with two-speed motor for 10 and 50 mm/min: the carriage supports 2 briquet molds. Automatic stop safety switch that stops the carriage when the maximum elongation has been reached. Traction length: 50, 100  or 150 cm.
• White screen fixed to the bottom of the bath: it permits a more clear vision of the elongated specimen during the test.
• For 220 V/50 Hz connections: 1800 W power consumption.
• Dimensions (l x w x h): mm 1800 x 450 x 1300 approx (AD0113-200) mm 2400 x 450 x 1300 approx (AD0113-250). Weight: 250 kg approx.

The apparatus consists of a constant temperature bath capable to work in the range from -10 to 40 °C (thanks to a built-in cooling compressor) with an electrically powered tractor that pulls apart at an selectable speed the two ends of two briquet specimens: a load cell records continuously the force applied to the briquets transmitting them plus the bath temperature and the carriage speed to a PC through the RS-232 serial interface or USB port (converter required): a data acquisition software permits to display data on graphs, store them on the hard-disk, obtain printed reports and calibrate temperature, force and elongation sensors

• Enamel finished steel case, floor mounted with swivelling castors.
• Stainless steel bath, thermally insulated, with drain valve.
• Chromium plated brass pump: it provides an adequate stirring of the liquid in the bath. Switch to turn it off during the test.
• Stainless steel heater.
• Microprocessor thermoregulator with PID action: built-in digital display 0.1°C accuracy. Probe: Pt100 RTD. Working range: from -10 to 40°C.
• Safety device against overheating and low level with alarm lamp.
• Built-in hermetic cooling compressor.
• Acrylic hinged cover: it helps to maintain a constant temperature in the bath providing a clear view of the inside.
• Traction carriage with variable speed motor: the carriage can contain 2 briquet molds. Automatic stop safety switch that stops the carriage when the maximum elongation has been reached. Traction length: 50, 100  or 150 cm.
• White PTFE screen fixed to the bottom of the bath: it permits a better vision of the test while in execution.
• Two load cells mechanically connected to the briquet molds. Range: 0 - 200 Newton: accuracy: 0.5 Newton.
• RS-232 serial interface for the connection to a PC: we can supply the instrument with a traditional desktop PC or the user can use one of his PC’s with the requirements reported in the “accessories” section here below.
• Data acquisition software running under Windows Xp/Vista/7: the software provides to record and show on graphs the force applied to the briquet molds, the elongation and the temperature of the bath. Data can be stored on a hard disk and printed. Software routines for calibration of temperature, force and elongation sensors.
• Easy access control box containing all the electronics: anodized aluminium control panel with english written indications.
• English written user manual with installation instructions.
• For 220 V/50 Hz connections: 1800 W power consumption.
• Dimensions (l x w x h): mm 1800 x 450 x 1300 approx. (100 cm version) 2400 x 450 x 1300 approx. (150 cm version). Weight: 250 kg approx.
• CE marked.

The H-1068 Ductility machine builds on the H-1068X machine and adds a circulating temperature-control unit. Solid-state thermostatically controlled bath and circulator maintain water temperature within a ± 0.18°F (± 0.1°C). The H-1068B is a three-speed machine designed for Standard and Force Ductility tests. The unit tests three briquettes simultaneously and its DC, direct-drive motor maintains constant speed, entirely vibration-free. Speeds of 1/4, 1 or 5cm per minute are selected via lever shift on mechanical gear box. A single stainless steel lead screw mounted above water level prevents agitation of water and premature rupture of specimens. A traveling pointer adjusts to zero starting position and indicates exact position of carriage on a linear centimeter scale attached to trough‘s front edge. Maximum carriage travel (elongation) is 150cm with an automatic stop. The Unit has a stainless steel interior with an overflow connection, and a baked-enamel, stainless steel-wrapped exterior. Gears are bronze or brass; all other parts are solid brass to prevent rusting. Finned stainless steel tubes beneath a false bottom provide efficient thermal transfer. Includes a 6' (183cm) cord, feed-through switch and 3-prong plug. Includes 3 standard H-1080 briquette molds with H-1090 plates. Trough overall dimensions: 11.75" x 74" x 6.375"H (30 x 188 x 16cm). H-1068PC Acrylic Cover is recommended to maintain constant tank temperatures. The Ductility Machine, Temperature-Controlled supports the following standards: ASTM D113, ASTM D5892, ASTM D6084, AASHTO T51
