NOYAFA MS12C Carbon Dioxide Detector

Brief Introduction

The JMS12C is a four-in-one air environmental quality detector that uses advanced sensors to detect carbon dioxide (CO2), formaldehyde, TVOC, temperature, and humidity at the same time. With the development of the economy and the improvement of quality of life, more and more people begin to pay attention to health and environmental protection. After the new home is renovated, in addition to basic ventilation and placement of formaldehyde plants, carbon bags, and other measures, many people will also use air quality detectors to fully detect air quality conditions, comprehensive protection of pregnant women, children, the elderly and family members of the health.

Instructions

1. Before the new machine is used, please place ii on the balcony or the huge external ventilation for more than 2 hours. (Avoid smelling places).
2. After pressing the power-on key for 5 seconds, start the 1 DO-second countdown and end the CO2 concentration and temperature and humidity display, formaldehyde concentration, and TVOC concentration display shows that after 80 seconds, this time can be calibrated.
3. Calibration will be the instrument to a huge outer air fresh good place, the instrument after 5 minutes of static long press and hold the brightness adjustment button 5 seconds for calibration, calibration began the instrument issued a long sound, 10 seconds after the successful calibration of the instrument again long chirp.
   Calibration Note:
   The air must be pure and well-ventilated during calibration, away from alcohol, perfume, etc., to avoid incorrect calibration. If clean air is not guaranteed, find a place with good air quality and recalibration.
4. Start detection: get the detection point position static for 3-5 minutes and can directly read the results. At the end of the inspection, press and hold the switch key for 5 seconds to shut down, and keep the instrument properly.
5. At the end of the test, press and hold the switch key for 5 seconds lo shut down, put away the instrument and keep ii safe.

Description of the measurement results

1. Excellent air quality, the screen shows “excellent”, and the resulting light is green.
2. Good air quality, the screen shows “good”, and the resulting light is green.
3. Poor air quality, the screen shows “poor”, and the resulting light is red, it is recommended to open the window immediately.
4. Air quality is bad, the screen shows “bad”, the resulting light is red, and buzzer ‘Drip’ sounds 5 alarms, indicating that formaldehyde or CO2 is seriously overshooting the standard.
