Zedflo ConST 811 automated pressure calibrator

The ConST 811 automated pressure calibrator, from Zedflo, is a compact, lightweight calibrator that can generate from 90% vacuum to 25 bar (375 psi) using its built-in, 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. With optional external pressure sensors, it can measure pressures up to 700 bar (10,000 psi), with 0.025% accuracy.

The unit has a large display with 7″ colour screen and an intuitive 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.

The device contains a leak test/switch test facility and full documenting facilities. Its internal memory stores 120 tasks and its rechargeable battery lasts for 8 h. The product brings automated pressure calibration to field test, service and commissioning applications.
