Humboldt Manufacturing - Testing Equipment for Construction Materials

Marshall/TSR Loader, Load Frame Only

The HM-1327 is a fully automatic, single-speed Load Frame, 2.0 inches/minute, (50mm/minute), designed for those who want a high-quality, Marshall/TSR-specific Load Frame that provides simple operation with built-in data acquisition capabilities. The HM-1327 provides two channels with integral data acquisition to accommodate a load cell and transducer for Marshall testing. The machines's digital display provides the ability to monitor test data in real-time, as well as the ability to see a test's peak value at a glance.

Features include:
• 8" platen provides roomy, stable base for test equipment
• Two channels with real-time data acquisition
• Backlit LCD displays test data and beak value at a glance
• Battery-backed, real-time clock
• RS232 interface provides computer control and downloading of test data.
• Chart recorder output.
• Nonvolatile test data storage and instrument calibration
• User-selectable Marshall or TSR test functions
• Machine auto reverses to home position at the end of test
• Automatic triggering of test data logging

HM-1327 includes just the load frame, as well as Humboldt's HMTS Reporting Software, Entry Level Version.

Digital Accessory Kit for H-1339B, 110-250V 50-60Hz

Twin-channel digital display for use with the H-1339. Includes S-type 10,000 lbf (45kN) load cell, 0.4" (10mm) linear strain transducer, and transducer bracket. Display: 12" x 10" x 4" (304 x 254 x 102mm).

Dual-Scale Chart Paper

Chart paper with dual-range scale that allows switching between 5000 and 10,000 lbf. Package of 100 sheets.

Multi-Speed Load Frame

The HM-2800 is a multi-use, multi-speed machine that provides a dedicated setting for Marshall testing in addition to its ability to provide variable speeds of operation between 0.008 and 2.000 inches/minute for doing the multitude of tests required by today's labs.

Multi-purpose Digital MasterLoader

The HM-3000 provides the ultimate lab solution of a multi-purpose load frame that can handle Marshall and Hveem tests with built-in test parameters, as well as soil tests such as CBR, UU, CU, CD and UC. The HM-3000 can work as a stand-alone unit, which can perform Marshall tests at the push of a button; or with the aid of Humboldt's HMTS software and a computer, be automated to run tests and gather data in real-time data acquisition in the form of charts and graphs. The HM-3000 is ideal for road construction projects in either mobile or fixed labs, educational institutions and consulting firms.n
