Innovative High Temperature Infrared Pyrometers

Endurance IR sensors have a rugged stainless steel housing designed to meet IP65 (NEMA 4) environmental requirements in high ambients up to 65°C (149ºF) without cooling.

Our innovative optional camera feature allows you to continuously monitor your process visually, while the LED sighting option allows you to see the spot size on the target and make sure you have a clean line of sight to the target. The match function takes the guesswork out of setting the emissivity.

Endurance companion software allows you to archive your process temperatures for data analysis and sensor setup.

The Endurance Series is supported by the best-in-class 4 year warranty.
