Ace AI-CO2 Series Carbon Dioxide Transmitter

KSh 20344

Ace AI-CO2 Series Carbon Dioxide Transmitter provides continuous online monitoring of CO2 for indoor environmental monitoring and controlling in mechanical applications, apparatus, parking area natural checking, and business structures. Ace AI-CO2 Series can be used for air monitoring of supply, exhaust, and return air in a critical environment.
Applications: HVAC, Greenhouse, Landfill gas, Confined space, Marine vessels, Ventilation management, Mining, & gas stores, etc.


Ace AI-CO2 Series Carbon Dioxide Transmitter accurately measures the Carbon Dioxide concentration levels in schools, office buildings, and other indoor environments. This single-beam dual-wavelength NDIR sensor has increased sensor life so that it automatically corrects the measurements in both occupied and unoccupied buildings against aging effects. AI-CO2 Series single beam wavelength sensor technology provides the highest level of accuracy.
