High-Temperature Infrared Pyrometers


High-Temperature Infrared Pyrometers

Endurance, High-Temperature Infrared Pyrometers

The innovative Endurance Series of low-temperature and high-temperature two-color pyrometers meets all the requirements of modern industry: it is flexible and easy to install; durable to withstand the most demanding harsh industrial environments; and visual – allowing you to see and understand your process temperature data.

  • Improve process control with a wide choice of spectral ranges and focus distances

  • Designed to handle wider temperature ranges (50°C to 3200 °C) with superior optical resolution to 300:1

  • Spot sizes down to 0.6mm with sighting options through-the-lens sighting, with optional laser, LED or video aiming function

  • Compact, rugged steel housing housings with IP65 (NEMA-4) rating to withstand ambient temperatures up to 65°C for integrated sensors and 315°C for fiber-optic sensors without cooling

  • Profinet and EtherNet/IP communication options with Programmable relay output for control
