• 1500mAh capacity: Adopting 3.7V 1500mAh large-capacity rechargeable lithium polymer battery, which can be charged repeatedly to save the use cost. Each instrument is equipped with a power protection chip, which can be connected to a charger to charge the product for real-time monitoring
• Temperature and humidity sensor: The sensor module has been calibrated, and there is no need to calibrate when in use; it adopts one-key power-on automatic calibration technology, which automatically detects when power-on, and does not require repeated calibration to cause misoperation.
• 3-inch large screen display: 76.3mm x 25.4mm size screen, one screen with four displays, the current air quality environment is clear at a glance, 178° viewing angle, you can read it whatever you want, with larger words and clearer.
• Sound and light alarm: The carbon dioxide data is updated every 3 seconds. When the concentration exceeds 1000ppm, the red light flashes. The default sound alarm is turned off. If the sound alarm is required, the user can turn on the sound alarm by pressing and holding the setting button. Function, at this time, there will be an audible alarm with the red backlight flashing.
• Automatic baseline calibration: It has automatic calibration and manual calibration functions to deal with various special working environments and special situations.
