XC-6000EM Automated Console for Paired Hg Sorbent Sampling. Features Proportional Valves w/Mass Flow Sensors, Pressure Transducers, DGMs w/Optical Encoders, Diaphragm Pumps. Ethernet/Modbus for DAS Interface and/or other Ethernet devices, USB Interface, 120VAC With Wired Router. (Laptop sold separately).

The MercSampler is a fully automated meter console for paired sampling. It simplifies sampling requirements by automating:

  • Display of Real-Time Data
  • Management of Proportional Flow Control
  • Data Export for Report Generation
  • Temperature Control
  • Easily Transferred to a Microsoft Windows-Based PC Through Various Forms of Communication
  • Data Acquisition, Logging and Processing
  • Calculations
  • Leak Checks
  • Calibrations

Installation: 19' Rack Mount Standard. Available 8U Transport case, ShockMount Rack or Weather Resistant Aluminum Cabinet Configurations.

The XC-6000 MercSampler meter console captures all data necessary for paired sorbent trap sampling according to PS 12B (Appendix K) and Method 30B. The meter console controls the sample flow rate proportionally to the stack flow rate and determines the standardized volume extracted through each sorbent trap. To collect the samples, two diaphragm vacuum pumps which work with the proportional valves and mass flow sensors, pull the samples through sorbent traps. The XC-6000 MercSampler simplifies most sampling requirements by automating data acquisition, sample flow adjustments, leak checks, calculations, temperature control, and calibrations. Data is easily transferred to a Microsoft Windows XP-based PC through Ethernet, USB or an optional Wireless Interface
