The XC-30B MercSampler™ Console, designed especially for performing Method 30B, simplifies sampling requirements by automating data acquisition, sample flow adjustments, leak checks, calculations, temperature control, and calibrations. Data is easily transferred to a Microsoft Windows Based PC through USB Interface.

• Fully automated for paired (dual sorbent trap) sampling per Method 30B
• Dual dry gas meters and mass flow sensors with sample flow rates up to 2.5 lpm
• Automated pre- and post-test leak checks, calibrations, and calculations
• Compact, portable system in a durable UHMW polyethylene case
• USB interface with simple data export to a Windows-based PC
• Windows-based MercSampler software configurable from local PC or remote network connection
