SENDOIL / Drilling instrumentation systemsSDZ3000-3 triple-panel LCD drilling instrumentation
When more parameters are to be displayed on the rig, the SDZ3000-3 rig parameters monitor is recommended. SDZ3000-3 uses a three-span LCD-based visible screen. In general, when the well team is required to display a full range of drilling parameters, it is possible to select a standard drilling parameter.
