Manual Compression Testing Machines
325K Manual Compression Machine, 2270 Digital, 1/2 hp
Meets ASTM C-39, E-4 and AASHTO T-22 specifications.
Also Available in Automatic Control
- Testing range of 3,250 to 325,000 lbs. (14.45 – 1,445.67 kN) with an accuracy of ±.5% of indicated load.
- Equipped with the TM-2270 digital load indicating system, an easy-to-use, economical indicator loaded with features found in a more expensive unit
Our TM-2270 indicator:
- ⦁ Displays both live load and rate of loading values during a test
⦁ Features easy-to-read 1” (25 mm) tall characters displaying force units in
lbf, kgf, kN and N; stress units in PSI or MPa; time units in seconds
or minutes
⦁ Holds seven different sample types with dimensions for easy test setups
⦁ Stores test data for 90 tests, including test date and time, sample ID
number, sample area, both peak load and stress, length of test, and average
rate of load for test documentation
⦁ Prints test results with an optional printer or transfers data USB to PC to
tabulate test results
The CM-3250, with its American-made, rigid steel-welded load frame, is built to last. The upper and lower crossheads are 4 inches thick with a ram that is 7 inches in diameter. These features make the CM-3250 one of the strongest machines in its class.
The load frame is manufactured with structural steel side members and solid steel crossheads. It also features our wrap-around box construction design with each corner fully welded on both the inside and outside crosshead seams, which provides the rugged stability needed for accurate and repeatable test results, year after year.
The CM-3250 comes ready to test 6" x 12" concrete cylinders. With additional spacers and accessories, it can test 2" x 4", 3" x 6", and 4" x 8" cylinders, beams, and 2-inch cement cubes. It can also conduct splitting tensile strength tests.
The digital indicator, loading control valve, and hydraulic pump are positioned on the right side of the load frame for easy access, increased productivity, and safer operation. Featuring a superior rate of load control, its quiet running, continuous-duty hydraulic pump and pressure-compensated loading control valve are manufactured to ISO 9001 international quality standards.
Standard safety features include steel fragment guard doors on both frame openings and a high-pressure hydraulic safety valve that prevents the machine from operating beyond its maximum capacity.
Optional accessories include test platen sets, spacers, machine-mounting stand, test cylinder loading shelf, and ¾ hp (.6kw) hydraulic pump package.
Warranty 2 years on parts and labor.
