ACCU-TEK 250 Digital SeriesASTM C-109, C-39;AASHTO T-22.

Selectable display in English or Metric units. Automatic stress calculation and display. Data storage and transfer capabilities for 500 tests. RS-232C communication port for use on personal computers. Adjusts for capping compound or capping pad method, by

removing the platen spacer. Includes platens for testing standard 2" (50.8 mm) cubes,

frame stand, and download software with RS-232 cable.

The lightweight, portable ACCU-TEK 250 Digital Series compression testeroffers economical, affordable quality testing on-site or in the lab. Each testerconsists of a heavy duty 250,000 lbf. (1,112 kN) capacity load frame, hydraulicpump and digital readout system.

Using microprocessor technology, the digital readout system automatically displaysload and stress calculations.The easy-to-use membrane keyboard makes selectionof operating parameters simple and a pace deviation bar graph allows for fineadjustment of the loading rate.The system features a large, backlit digital display foreasy viewing.

The compact single unit design offers a large surface area on the lower platen anda 9" (229 mm) wide horizontal opening between the steel uprights.All hydraulicpump operating controls are mounted on the front of the unit for easy access, andthe built-in overload protection provides machine and operator safety.

Supplied complete with standard platens, the ACCU-TEKTM 250 machines can test6" x 12" (152 x 305 mm) cylinders, using either the capping compound or cappingpad methods. Included attachments make it easy to perform tests on 2 (50 mm)

cube samples.The complete system meets ASTM C-109, C-39 and AASHTO T-22 specificationscovering the design and accuracy of hydraulic testing machines.
