Whether in a confined space or an open area, Model G450 is easy to operate, read and carry. It continuously detects and measures O2, H2S, carbon monoxide and combustible gases in ambient air. Features include precalibrated sensors and AutoCal automatic calibration; an extra large, invertible, heterochromatic display; rotating 360o bright, flashing alarms; and a 103 dB buzzer. The watertight design (IP67) provides an impact-proof rubberized housing.
