UPstream Sampling Systems

Spot Sample Stations for Upstream Applications

Mechatest design liquid and gas sampling systems that can take spot samples of upstream applications in the petrochemical industry.

The systems with sample cylinder enable operators to obtain samples of fluids with high process pressure in hazardous and (toxic) sour applications.

Importance of Sample Probes

Mechatest Gas Sample Probe

Sample probes are very important and mostly an underestimated part of the sampling system.
Why you should use sample probes;

  • Free First Filtration Effect!
  • Faster Response (< Lag Time)
  • Representative Sample, better results!
  • Moisture Filtration (fallback) Principle
