Nomad-Direct™ 2-Channel Portable Fiber Optic Temperature Test Device
Qualitrol is pleased to announce the launch of Nomad-Direct™, the next generation of the Nomad product family and the successor to the legacy Nomad Touch (NMT). While Nomad Touch has served customers reliably for many years, Nomad-Direct was developed to better support modern transformer manufacturing with a simpler and more efficient design.
Nomad-Direct is purpose-built for fast, repeatable, point-in-time temperature validation without the need for external software or PC connectivity. Key benefits include:
- Dual-channel measurement for faster probe validation
- Standalone operation with no PC software or firmware updates required
- USB-C charging with global compatibility (adapter included)
Nomad-Direct maintains compatibility with existing Neoptix GaAs fiber-optic probes while streamlining operation for customers who require quick, dependable temperature verification.
