Model: IBI-A-C485
The IBI-A-C485 uses Non-Dispersive Infrared (NDIR) dual-beam technology to measure CO2 by detecting infrared absorption at a CO2-specific wavelength.
The IBI-A-C485 uses Non-Dispersive Infrared (NDIR) dual-beam technology to measure CO2 by detecting infrared absorption at a CO2-specific wavelength.
The dual-beam design continuously compares a measurement channel against a reference channel to compensate for light-source aging, dust, and optics contamination—yielding high long-term stability and low drift.
The diffusion-based sampling design supports continuous 24×7 operation with low maintenance.
Digital communications via RS-485 (Modbus RTU) ensure easy integration with BMS, HVAC/DCV, PLC, and SCADA systems.
Standardized registers enable plug-and-play mapping and rapid commissioning.
Proven performance in critical applications with 99.9% uptime
Industry-leading sensor precision ensures data integrity
Meets FDA, ISO, and industry standards for regulated environments
