The compact Impac® IN 2000 and IN 3000 stationary infrared sensors are ideal for non-contact temperature measurement of non-metallic surfaces as well as painted, coated, and anodized metals. Their solid and robust design allows for use in rough industrial environments. They each have a built-in air purge to protect their lenses from dust and moisture contamination, which allows the devices to adapt to various measuring tasks.

The IN 3000 is an analog measuring device with three different outputs. The IN 2000 is a digital pyrometer equipped with an interface output for USB connection. You can adjustment all IN 2000 parameters via PC.


  • Use in small spaces
  • Easily mount
  • Keep the lens clean in dusty environments via the air-purge unit
  • Adapt to various measuring tasks
  • Easily install and connect


  • Solid and robust design
  • Up to 70°C operating temperature with no need for cooling
  • IN 3000: Analog device with three outputs
  • IN 2000: Digital pyrometer with USB connectivity
  • Built-in air purge
