FujiElectric Infrared gas analyzer for ZFG heat treatment furnace

FujiElectric Infrared gas analyzer for ZFG heat treatment furnace

FujiElectric ZFG type

    peculiarity

   Gas analyzer for measuring ambient gas concentration in heat treatment furnaces.

   Precise measurement of the gas concentration in the furnace

   Repeatability: ±0.5%

   CP (Carbon Potential) calculation output and display (option)

   Because it adopts a single beam type, it has excellent long-term stability and easy maintenance

   The gas concentrations of the two components are measured sequentially at the same time

   Compact and lightweight: about 5Kg
