A+ Series

Highly Accurate Infrared Pyrometers with Focusable Optics
The A+ series of pyrometers represents highly accurate digital IR focusable pyrometers designed to deliver exceptional performance and low maintenance for non-contact temperature measurements in demanding industrial and R&D environments.


Key Features:

  • Integrated OLED Display & Parameterizing Keys: The A+ series pyrometers come equipped with an integrated OLED display and parameterizing keys conveniently located on the back panel. Using the intuitive keypad interface, enables users to easily set parameters such as emissivity, response time, and peak picker.
  • Sighting Options: Choose from laser-targeting, through-the-lens viewfinder, and video sighting options, providing flexibility to suit various measurement scenarios.
  • Single and Two-Color Models: The A+ series available in both single-colour pyrometers (A250+ and A450+) and a specialized two-color models (A450C+). Additionally, these pyrometers allow seamless switching between single and two-color modes to cater to different application needs.
  • Analog Output: Available analog output options 0…20mA/4…20mA and an RS-485 serial interface with MODBUS protocol ensuring smooth data transmission and integration with other systems.
  • LED Indication: The pyrometers are equipped with a green LED for pyrometer status indication and a red LED for laser ON/OFF indication, facilitating easy operation and monitoring.
  • User-Friendly Infrasoft PC Software: Simplify communication and data management with the user-friendly Infrasoft PC software provided with the A+ series.
  • Measurement Stability: The A+ series pyrometers maintain measurement stability even when switching the laser ON/OFF.
