The Air Quality Meter Gasman-O3 is a unique gas meter which protects against a specific gas, inflammable or toxic. The Air Quality Meter warns with a penetrating alarm and an optical signal (useful in case when there are loud noises in the surroundings) of the existence of dangerous gas concentrations and shows on screen the value of the gas measurement. The Air Quality Meter fulfills all the European and international norms, even ATEX and UL standards.

• For O3 (Ozone)
• Dust and water resistant - IP 65/67
• 0 … 1 ppm
• Non-rechargeable, 1-year battery
