CO2 Monitor Marvel 001 Carbon Dioxide Concentration Meter with Thermometer and Hygrometer High Precision Optical NDIR Dual Beam Sensor Infectious

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. As a measure against infectious diseases, you can easily check the indoor ventilation status. Please use it to "visualize ventilation" in homes, offices, schools, commercial facilities, hospitals, nursing homes, etc. ① Installation method: Tabletop (rear stand) Wall mount possible ②Measurement range: CO2 concentration 0 to 5,000 ppm, temperature 0 to 50°C, humidity 20 to 90% can be displayed. ③High-precision NDIR (non-dispersive infrared absorption) dual beam sensor is used, resulting in little measurement error even after long-term use. ④Power supply: DC5 V USB cable specification (Mini USB side connection AC adapter included)
