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.
