About
The NeoSapphire electronic downhole gauges are designed with low costs and easy to use as the main criteria. It can be used as memory gauge or surface readout (SRO) gauge. The gauge also writes data into gauge memory at SRO mode to have data backup and integrity. It can be run by field personnel with limited computer and electronic product knowledge.
The typical applications of this model include slickline gradient and pressure build-up jobs. With a unique low power consumption design, a single C battery can run over a year at regular operations. MaxView and MaxSRO software allows operators to conduct programming, downloading, and reporting very easily.
