i7 Digital Indicator

Supports the following standards: AASHTO T22, ASTM C39, ASTM E4

The i7 is an easy-to-use digital load indicator that simultaneously displays both live load and rate of load values during a test. It eliminates the need to toggle keys between functions, and, automatically displays peak load and average rate of load at the end of each test.

All test information is clearly displayed on the indicator's 5.3" (135 mm) wide 240 x 64 pixel backlit V.G.A., liquid-crystal display with adjustable contrast settings. Test data is displayed in user selectable engineering units of lbs, kN, kg and N with rate of load displayed in force units per second.

The indicator will store up to 600 tests in memory, and transfer them directly into a word document via the optional USB Able Cable, or print them on an optional serial printer. Stored test data includes; test date and time, sample ID number, peak load and average rate of load. The average rate of load calculation is based on the average load rate applied to the sample during the second half of the test.

Built for the harshest laboratory environments, all of its internal electrical components are protected in a NEMA-4 rated water/dust-proof stainless steel enclosure, making it an ideal choice for mobile field laboratories where excessively high humidity levels are present. Its approvals and listing are NEMA-4, UL, CUL, CE and Measurement Canada.

It features smooth and uniform control of load pacing rates through its high speed sampling rates and digital filtering. Accuracy exceeds ASTM C39 and E4 requirements and is achieved through a calibration program with 5 linearization points, 0 and span; and, in general, is better than ± .5% of indicated load. Its calibration program is password protected. Power requirements 115/230V 50/60Hz/1 Ph.

The i7 is available as a retrofit package.
