Designed to control the flow of air and ALL inert gases and mixtures, the innovative nylon construction of the MassTrak 810 meets the same performance criteria as any industry-standard mass flow controller at an affordable price.

This affordable flow control option includes:

  • Control valve featuring a purge mode
  • Valve close command from an external contact
  • Built-in setpoint control and 24 VDC power supply

These eliminate the need for a separate power supply and readout electronics that can cost as much as a new mass flow controller.

Save money and get accurate results with the MassTrak 810.

  • Record flow measurement at affordable OEM pricing
  • Save money with volume discounts
  • Read results easily  with large LCD readout
  • Accurate mass flow control even with low pressure drop
  • Save time with built-in setpoint control

  • Ideal for OEM and general industry applications
  • On-board display and local setpoint control eliminates need for external electronics
  • Large, straight sensor tube reduces contamination and maintenance down-time
