Humboldt Ductility Machine

The H-1068X is a three-speed machine designed for Standard and Force Ductility tests. The unit tests three briquets 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 brass 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 briquet molds with H-1090 plates.

Trough overall dimension: 11-3/4 x 74 x 6-3/8"H.H-1068PC Plastic Cover is recommended to maintain constant tank temperatures.

Temperature Controlled Ductility Machine

The H-1068 Ductility machine takes our 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). All features identical to the H-1068X. Includes three H-1080 molds. H-1068PC Plastic Cover is recommended to maintain constant tank temperatures. Shipping wt. 430 lbs. (195 kg)

Circulating Temperature Controller

The H-1068C Circulating Temperature Controller is designed for use with the H-1068X Ductility Machine. It provides a solid-state, thermostatically controlled bath and circulator to maintain water temperature within a ± 0.9°F (± 0.5°C).

Clear Cover for Ductility Machine

Temperature control cover made from clear Plexiglas. Can be used with all ductility machines. Shipping wt. 40 lbs (18kg), (cannot ship via UPS)

Basic Ductility Machine

The H-1050 is a three-speed machine designed for Standard and Force Ductility tests. The unit is a lower cost machine, identical to the H-1068X except that it does not include the baked enamel stainless steel-wrapped exterior or the thermal finned stainless steel tubes in the bottom for enhanced thermal transfer. Shipping wt. 200 lbs. (90.7 kg)

Electronic-controlled Ductility Machine

Same machine as the Basic H-1050, but includes a solid-state speed controller, which continually adjusts feedback to maintain even and proper speed. Direct drive 1/40 HP DC motor pulls carriage at 1/4, 1 or 5cm/min.

Single-speed Ductility Machine

Same machine as the Basic H-1050, but operates only at one speed: 5cm/min. Machine uses a direct drive 1/75 HP AC motor.

Refrigerated Ductility Machine, 220V 60Hz

This Refrigerated Ductility Machine features the H-1050 machine mounted into a polypropylene bath designed for use with sodium chloride solutions. The heavy-gauge, enamel-finish steel cabinet is fully-insulated and the sealed space between the inner and outer walls protects the low-thermal conductivity properties of the foam and fiberglass combination (tested and proven to have the best K factor). High-capacity pump assures positive circulation in bath to give close temperature control. Three-direction flow regulation is handled with flow cut-off valves that engage when equilibrium is reached. Sensitive magnetic setting transistorized electronic relay control panel for heat and refrigeration maintains temperature range of 32°F (0°C) to 86°F (30°C) by 0.1°F (0.1°C). Cabinet is 90 x 41 x 23". Includes 3 H-1080 molds.
