A bright blue backlight and laser guide make taking fast and accurate temperature readings easier, better and faster. The SIG1 comes with a protective lens cap and body wrap. It works faster than thermistor-based temperature instruments and has a range of -22°F to 1022°F. Includes Auto-Power Off to conserve battery life.
