The HA-1068 Controller provides precise speed control of the DC, stepper motor maintaining constant speed, entirely vibration-free, from 5 to 100mm/min. The unit provides for three test briquettes per testing sequence with a maximum carriage travel (elongation) of 150cm and an automatic stop feature. The machine also provides a manual disengage lever for quickly disengaging the screw drive to return the testing carriage back to the start position after a test completion. This feature allows multiple tests to be run without having to wait for the machine to reset itself.
The HA-1068 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. 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.
In stand-alone mode the controller provides you with full, graphical monitoring of all testing functions, while maintaining full computer control when desired. The seven-inch, waterproof screen provides at-a-glance monitoring of testing functions, in a real-time graphical display, without the use of a computer, building upon Humboldt’s dedication to modular, stand-alone data acquisition.
You will be able to run tests and display results while viewing tabulation, basic x-y graphs and instrument readings in real-time during the test, using user-defined, basic data acquisition. Test data is stored in the device and can be down-loaded to a USB drive via the machine’s FRONT USB port or the data can be transferred to a computer via the LAN port.
A second USB port located on the back of the machine can also be used to power a wireless access point, which can provide a wireless hook-up with a computer, if no LAN is available.
The HA-1068 Ductilometer is sold without a circulating temperature controller. If desired, choose a circulating temperature controller with the correct AC requirements. The temperature-controller provides a solid-state, thermostatically controlled bath and circulator to maintain water temperature within a ±0.9°F (±0.5°C). The temperature range is:
-10°C to 80°C and the heating capacity is 1000W with a 0.1°C stability. Includes a 6′ (183cm) cord, feed-through switch and 3-prong plug and 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). Acrylic Cover is included with this machine.
