(* 1) The value obtained by dividing the integrated value of the average concentration of carbon monoxide gas for 1 minute by 60 minutes is displayed as the integrated concentration. (The unit is officially ppm · h, but for convenience, it is ppm.)
(* 2) Some mobile terminals may affect the device, so be careful when using it near the mobile terminal. |
