Permanent Monitoring
Quartz Permanent High Temp Hybrid
The QP225H measures pressure and temperature in real time for high-temperature permanent applications. It consists of a Quartz Pressure Gauge coupled with Hybrid Electronics. This combination of proven technologies in a permanent downhole monitoring system enables it in the most severe and extreme conditions while providing reliable and accurate data.
Applications
The QP225H was developed to provide a long-term pressure and temperature solution for the SAGD and Geothermal markets.
