The IS200 provides accessible control for electro-hydraulic valve actuators within Zone 0 areas, typically on a choke valve at the wellhead.
Full manual control, calibration and configuration is available on the front panel of the instrument and, because of IS certification, all operations are available when the hazard is present.
