KOTITI, designated as an environmental measuring instrument inspection agency and a performance certification body for simplified measuring instruments, provides services aimed at reducing environmental pollution and improving air quality.
Through precision inspection and equivalency evaluation of environmental measuring instruments, performance certification and inspection of simplified measuring instruments, and greenhouse gas reduction efficiency measurement, we support accurate environmental data acquisition and the establishment of effective environmental management systems.

Equivalency Evaluation Test
Target Equipment and Test Period
Particulate matter (PM-10) continuous ambient air monitor: 14 consecutive days
Fine particulate matter (PM-2.5) continuous ambient air monitor: 23 consecutive days
Performance Certification of PM Portable Monitors
Fine Particulate Matter (PM-2.5)
Conducted under Article 24 of the Special Act on Fine Dust Reduction and Management for PM monitors that have not received type approval or preliminary type approval.
Validity of certification: 5 years
Performance Inspection of PM Portable Monitors
Fine Particulate Matter (PM-2.5)
Under Article 24 of the Special Act on Fine Dust Reduction and Management, operators who disclose measurement results to the public must have the performance of their portable monitors regularly inspected.
Inspection cycle: 2 years and 6 months
Performance Certification of Portable Monitors in Air Quality
Air Quality Portable Monitors (Nitrogen dioxide, carbon monoxide, ozone)
Under Article 9-3 of the Act on Testing and Inspection in the Environmental Field, manufacturers or importers of portable monitors (including sensor-type monitors not subject to type or preliminary type approval as defined by the Ministry of Climate, Energy and Environment regulations) must obtain performance certification.
Greenhouse Gas Scrubber Reduction Efficiency Measurement
Under Article 9 of the Guidelines for Reporting and Verification of Greenhouse Gas Emissions under the Emissions Trading Scheme, designated reporting entities must ensure that all greenhouse gas emissions are accurately calculated.
Destruction and Removal Efficiency (DRE)
DRE indicates how effectively a reduction device (e.g., a scrubber) removes or decomposes greenhouse gases.
The efficiency is measured by simultaneously analyzing the gas at the inlet and outlet of the reduction facility.
Vin: Total gas volume entering the reduction facilityVout: Total gas volume exiting the reduction facility
Target Facilities and Measurement Items
Target facilities: Semiconductor and display manufacturing plants, scrubber manufacturers
Measurement items: Greenhouse gases such as CF4, C2F6, C3F8, C4F8, C5F8, CH2F2, CHF3, N2O, SF6, NF3, etc.
