DESCRIPTION:
YEM-42 series instruments are mainly used for environmental carbon dioxide concentration, temperature and humidity monitoring, suitable for homes, classrooms and offices.
YEM-42 uses a high-definition black-bottom color screen, and the screen brightness can be set with buttons. The instrument responds quickly, the temperature and humidity measurement interval is 1 second, and the carbon dioxide concentration measurement interval is 4 seconds.
On the basis of YEM-42, YEM-42S/42H uses high-precision sensors to improve the measurement accuracy of carbon dioxide.
| FEATURES: HD black bottom color screen NDIR carbon dioxide sensor Human comfort index Carbon dioxide limit alarm Carbon dioxide User Calibration Screen brightness is adjustable Battery status indication | APPLICATION: • Shopping mall • Hospital • Restaurant • School • Home furnishing • Office space environment testing • Agricultural greenhouses, breeding • Laboratory |
