Fast sampling within 50 ms and high accuracy of ±0.2%
Socket type available


  • Precise control
    Achieved a processing speed of 50 ms which is 10 times faster than conventional models. Reading accuracy is also improved from ±0.5% to ±0.2%*.
    *Comparison under 0–850°C range, with RTD. See the Data Sheet for details.
  • Easy-to-see display
    MVA LCD* which offers high contrast and wide viewing angle
    Process value is displayed in white
    *Minimal translucent type vertical alignment liquid crystal display
  • Practical options
    Simple watt-hour metering function: allows you to monitor energy consumption
    Operating days alarm: tells you the appropriate time for maintenance work
  • Most compact class in industry
    36% smaller (than conventional models) and 58-mm depth shallow body helps downsize your facility
  • Universal input
    You can use any input among RTD, thermocouples, voltage, current, and mV. The set-up for input change is very easy, only requires parameter change. This allows reduction of maintenance parts.

Directly connectable to PC with optional USB cable

PXF requires no power supply because it is bus-powered.
