The O425-LS-Series handheld infrared thermometer is a non-contact temperature measuring device. The unit comes in two versions: Standard, OS425-LS: -60 to 1000°C (-76 to 1832°F), and High Temperature, OS425HT-LS: -60 to 1500°C (-76 to 2732°F). Along with a magnetic mount, the OS425-LS offers circle-dot laser sighting, several mathematical modes, and adjustable emissivity. Long battery life (typically 180 hours without laser or backlight), is obtained from 2 “AAA” batteries along with automatic shut-off. The 50:1 field of view measures small and distant targets. Display backlight and built-in flashlight (enabled when laser is enabled) allow night and low light viewing.
