The Nitromat-M is a single-channel measuring and control system for furnace atmosphere- control in Nitriding- or Nitrocarburizing processes.

By switch settings on the backside of the instrument, Nitromat-M can be easily adapted to different sensor connections.

 The program controls of temperature and hydrogen, with program tracks for NH3 – N2 – Endogas – CO2, etc. eligible, is a propitious possibility for control Nitriding- or Nitrocarburizing atmospheres in furnaces.
