The Best Material For Downhole Capillary Tube: Duplex 2205 vs. Stainless Steel 316L
We put Duplex 2205 and Stainless Steel 316L head-to-head to see which is best for
This advanced downhole gauge utilizes a specialized QuartzdyneTM transducer. The industry standard for downhole precision pressure equipment.
GEOQ 125 – Downhole Quartz Gauge
The GEOQ 125 Quartz Gauge is an advanced digital tool that is designed to provide high-quality downhole pressure and temperature data. Our QuartzdyneTM downhole gauges provide the absolute best resolution and accuracy for pressure & temperature. At GEO PSI we only use QuartzdyneTM pressure transducers equipped with hybrid sensor circuitry which dramatically increases circuit life.
