Description
Overview
GAOTek Maintenance-Free Carbon Monoxide Detector is a highly efficient gas detection device equipped with an LCD dot matrix display, highlighting gas type, unit, concentration, and local time. Offering dual language support (Chinese and English), it allows for easy language switching. The detector provides rapid shifting between gas concentration units (PPM and mg/m3). With explosion-proof certification (II 2G Ex ia IIC T4 Ga IP66), it ensures safety in hazardous environments. Monitoring hydrogen gas concentration in both enclosed spaces and the environment triggers timely alarms. Featuring self-calibration and zero calibration functions, it guarantees accurate and reliable gas detection. The two-stage alarm with sound and light is customizable, and its rechargeable lithium polymer battery ensures prolonged usage.
