CO2Lamp CO2 Sensor Nagaoka Fireworks Model Carbon Dioxide CO2 Concentration with Alarm High Precision Measuring Instrument Domestic Production Made in

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. CO2 concentration measuring device "CO2lamp" - Reliably made in Japan - Adopts a next-generation optical sensor recommended by the Ministry of Economy, Trade and Industry in the "Guidelines for Selection of Carbon Dioxide Concentration Measuring Instruments." A ``light'' informs you of ventilation guidelines from a distance and 360° in all directions. The light is blue during normal times, changes to yellow when caution is required, and red when ventilation is required, so you can check the current situation from a distance. Equipped with a sensor that utilizes the fact that carbon dioxide reacts to infrared wavelengths, it accurately detects the concentration of carbon dioxide in a closed space. When installed in places where people gather, such as restaurants, schools, and offices, it is effective as an infection prevention measure by monitoring ventilation conditions. More detailed information can be found on the official website. https://www.prpage.biz/co2lamp/ ① ・Operating temperature/humidity range 0~40℃ / 0~95%RH (no condensation) ・Storage temperature/humidity range -20~60℃ / 0~95%RH (no condensation) ・Detection target gas Carbon dioxide gas (CO2) in the atmosphere ・CO2 concentration detection method: Photoacoustic method *Similar to the NDIR method, this method uses an optical sensor to detect only carbon dioxide in the air. ・Measurement interval of CO2 concentration: Every 5 seconds for 5 minutes after the power is turned on / Every 30 seconds thereafter ・USB input DC5V 0.5A ・Battery: 2 x AAA alkaline batteries ・Battery life (when powered continuously) "Bright": Approx. 20 hours / "Standard": Approx. 40 hours / "Dark": Approx. 80 hours (Reference values, not guaranteed values.) ・Data stabilization time after power on Initial stabilization time: Approx. 15 seconds / Complete stabilization time: Approx. 3 minutes ・External dimensions: Diameter approx. 82mm x Height approx. 60mm ・Weight: Approximately 100g (body excluding battery) ② [Large light emitter and buzzer inform you of concentration] The large light emitter on the top allows for confirmation from a distance or 360°. If the CO2 concentration increases, it will notify you with a color and a buzzer, and encourage ventilation by visualizing the state of the room. [Equipped with next-generation CO2 sensor (photoacoustic type)] Photoacoustic (PAS) CO2 sensors are different from simple gas sensors; they are next-generation compact sensors that utilize the fact that CO2 responds to infrared wavelengths, similar to the non-dispersive infrared absorption (NDIR) recommended by the Ministry of Health, Labor and Welfare. Accurately detects carbon dioxide concentration in closed spaces. [Design that blends into the interior] The simple and streamlined design blends naturally into your daily life without disrupting the atmosphere of your interior, so you can incorporate it anywhere.
