Memory Based Monitoring
QM200 & QM200S Quartz Tool
Our flagship quartz high temperature memory tool.
The Quartz QM200 a 1.25" quartz downhole gauge ideal for high-temperature reservoir environments. It provides exceptional downhole data quality measuring pressure and temperature. Using state-of-the-art digital hybrid technology, each sensor circuit is fully contained in a hermetic package for operation in temperatures of up to 200°C.
The QM200S has a 0.75" OD for slimmer applications and has the benefit of a faster response.
Why the Quartz QM200?
- Use in high-temperature situations
- Replace memory modules in the field
- Get the highest data quality on the market
- Convert to Surface Readout (SRO) mode
- Save data into two memory banks, or double memory capabilities with redundant and sequential memory mode operation
Applications
- High-temperature environments of up to 200°C
- Temperature testing environments that demand extreme accuracy
- Drill Stem Testing (DST)
