Key Features

  • Digital infrared sensor with 4-20 mA analog output and interface output for PC connection with USB.
  • Built-in air purge unit to keep clean the lens in dusty environments
  • Easy installation and connecting
  • Stainless steel housing with PG 11 thread for easy mounting
  • Very small housing dimensions, suited for use in confined spaces
  • Up to 70°C operating temperature without cooling


The IN 2000 is a good value stationary infrared sensors for non-contact temperature measurement of non-metallic surfaces or painted, coated or anodized metals.
The small housing dimensions enable the integration of the instruments in compact production machines; the solid and robust design of the instrument guarantees reliability even in rough industrial environments. With the built-in air purge the lens can be protected from contamination with dust and moisture. This enables the instrument to be adapted to various measuring tasks.

The IN 2000 is a digital pyrometer equipped with a interface output for connection to an USB adapter. This enables the adjustment of all pyrometer parameters via PC.
