Ozone Gas Detector MHK-OZ1
MHK-OZ1 is an ultrasensitive Ozone gas detector with 0.001 ppm (=1 PPP) resolution for monitoring low level ozone (O3) in the air. It has been designed to notify of the presence of low level O3 gas. MHK-OZ1 has a wide range of applications in industrial, business, home or R&D and other fields.

Alarm
Low Alarm and High Alarm
MHK-OZ1 has two alarm set points: High Alarm (O3: 1.00 PPM) and Low Alarm (O3: 0.500 PPM). These set points are factory set and cannot be changed. MHK-OZ1 is equipped with audio alarms to alert you when the ambient gas concentration exceeds one of the two alarm set points. When O3 value exceeds the defined high alarm set point (1.000 PPM), the audio alarm will sound at 3 beeps/sec. When O3 value exceeds the defined low alarm set point (0.500 PPM) but less than the defined high alarm set point (1.000 PPM), the audio alarm will sound at 2 beeps/sec.
