InfiRay Jerry-YM 627 Thermal Monocular
The InfiRay Jerry-YM 627 is a compact 640 x 512 thermal monocular for handheld scanning, helmet-mounted observation or compatible clip-on use. Its small housing and high-resolution thermal core make it a practical option where size, weight and image detail matter.
Kaelor Works presents the core sensor, display and housing information clearly so buyers can compare the Jerry-YM 627 against other 640-class thermal imaging devices without relying on exaggerated detection claims.
