Fit 220 HT

Omni-ID’s Fit 220 High Temperature tag is the smallest regional RFID tag with the capability to survive cycling applications to +235oC. The performance of the Fit 220 tag is not sacrificed by its small size and it is an ideal solution for tracking very small metal assets where space is limited. 


With its regional performance, high temperature capability and very small form factor, the Omni-ID Fit 220 tags are ideally suited to tracking small metal assets in applications such as:

  • Small Hand Tools
  • IT assets
  • Healthcare instruments
