Zedflo ConST 811 automated pressure calibrator

The ConST 811 automated pressure calibrator, from Zedflo, is a compact, lightweight pressure calibrator that can generate from 90% vacuum to +25 bar (375 psi) using its integral high-performance pump.

The easy-to-use calibrator can automatically provide the required pressure with a control stability of 0.005% FS and accuracy of 0.02% FS.

The unit has a large easy-to-read display with 7″ colour screen and an icon-driven menu structure for device-under-test and task selection.

Hart communications is supported and 24 VDC loop power is provided, as well as reading the current or voltage of the pressure transmitter or transducer under test.

With optional external pressure sensors, the calibrator can measure pressures up to 700 bar (10,000 psi), with 0.025% accuracy.

The ConST 811 has a rechargeable battery that supports eight hours of operation between charges, an internal memory that can store up to 120 tasks, and full documenting facilities.
