Sierra MassTrak 810 Economical Digital Mass Flow Controller

Sierra MassTrak 810 Economical Digital Mass Flow Controller capabilities at an attractive price. Available in any range from 0 to 10 sccm to 0 to 50 slpm, the 810C is suitable for any clean, non-corrosive gas flow control application.

MassTrak’s on-board display and local set point potentiometer allows for adjustment of the command signal from the face of the instrument enclosure and eliminates the need for external readout/set point electronics. The instrument also offers a switch-selectable remote set point capability from either a 4 to 20 mA or 0 to 5 VDC command signal, which can be easily interfaced with a process control system or workstation.

The instruments’ built-in, electromagnetic, servocontrol valve offers both a purge mode and a valve-close command from an external contact, a fast response to set point changes and a 0.25% repeatability specification. Designed to reduce costs in analytical, laboratory and OEM instrument applications, MassTrak provides all the performance features of a standard mass flow controller at an affordable price!
