NDIR (Non-Dispersive Infrared) technology is a spectroscopic sensor used for gas analysis. It is highly valued for CO2 monitoring because it offers excellent long-term stability and high accuracy compared to other sensor types.
The device features a 1000mA internal rechargeable Li battery that can provide up to 48 hours of continuous monitoring without an external power source.
The indicator bar changes based on CO2 concentration: Green is for healthy levels (< 800ppm), Yellow for caution (800-1200ppm), and Red for high concentration (> 1200ppm).
No, it is a plug-and-play desktop device. Simply connect it to a Type-C USB power source for the initial 15-second warmup, and it will start monitoring immediately.
Yes, the AKn16 is ideal for greenhouses, schools, offices, and homes where tracking CO2 levels is critical for plant growth or human health.
Yes, the device features an adjustable three-stage backlight function which can be switched easily using the main function key.
