III. Working Principle

Adopt NDIR Infrared Absorption Principle: Solid-state infrared LED emits specific wavelength infrared light, CO₂ gas will absorb the light of this wavelength; the detector collects the degree of light intensity attenuation, and the internal MCU converts it into the volume concentration of CO₂.

Gold-plated sealed gas chamber reduces light loss and improves accuracy; there is no easily worn heating filament, no poisoning, drift failure problems, and extremely strong long-term stability.

IV. Core Advantages

Ultra-low Power Consumption 3.5mW: suitable for battery-powered portable devices, backup power medical equipment; own heat generation is very small, does not interfere with temperature control of incubators

5% Range Precisely Match Cell Culture: Special range for biological laboratory standard conditions, stable accuracy

Extremely Long Service Life > 15 years, no frequent replacement, low maintenance cost

Shockproof and Strong: no mechanical parts, suitable for vehicle-mounted, field, mobile instruments

Data output immediately upon power-on, no need for long preheating, concentration quickly restored for monitoring upon opening

Digital UART Output, directly connected to microcontrollers, PLCs, development simple
