C02 detector, air quality analyzer, temperature and humidity analyzer, gas concentration and carbon dioxide analyzer

1. Temperature measurement range of - 20 ° to 60 ± 2 ° 2. Humidity measurement range of 5% ~ 95% ± 5.3. Carbon dioxide measurement range of 0-5000ppm, resolution of 1ppm, measurement accuracy of ± 50ppm ± 5%. 4. 0-499ppm display is green, 500ppm-999ppm display is yellow, 1000ppm-1499ppm display is orange, 1500ppm and above display is red 5. Long press the button for 2 seconds to start the machine, and the corresponding temperature, humidity and carbon dioxide concentration can be quickly detected within 7 seconds. It can accurately display the battery power, which is 25% 50% 75% 100% in turn. When the power is lower than 0, the battery symbol flashes for one minute and then turns off. Alarm function: when the carbon dioxide concentration reaches 1500, the corresponding red status bar on the screen will be on, and the buzzer will send out a drop tone alarm. At this time, press the button briefly to turn off the alarm tone. If the carbon dioxide concentration is still higher than 1500ppm, press the button again, and the buzzer will restore the drop alarm tone 7. The working temperature is 0-50 ° and the working humidity is 0-95% (non condensing). Our company is a manufacturer, with quantity and price, and OEM own patent
