Advanced Energy's Luxtron® m924 OEM module uses Fluoroptic® technology. It consists of the electronics module assembly plus Luxtron probes and accessories. The m924 provides precise and repeatable in-situ temperature measurements for control of processes involving RF, EMI, magnetic fields, and high voltages.

The m924 module replaces the Luxtron m600 OEM series module and FOT lab kit and provides better performance and modern architecture.


  • Easily integrate into OEM equipment
  • Utilize experienced application support and custom probes for medical and general purpose applications
  • Achieve better performance and a modern architecture
  • Measure temperature on minute samples without perturbing or heat sinking the sample
  • Receive support from experienced applications engineers to customize probes for medical and general purpose applications


  • Four channels, expandable up to 64 with RS485 Modbus
  • Single PCB design with options for analog output and metal enclosure
  • Proven Luxtron Fluoroptic STB and STF probes, immune to electromagnetic interference, such as high voltage, RF, plasma, and microwave
  • Backward compatibility with Luxtron m600 series OEM module, FOT Lab Kit, and Luxtron Fluoroptic Probes
  • Options for 0 to 10 V and 4 to 20 mA analog output and metal enclosure for lab and R&D applications
