- Model 810 - Economical Digital Mass Flow Controllers



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
