CO2 sensor controller Marvel NMA-VRC-II series (standard size) for "visualization of ventilation" infection measures
Sea Hichi Sea System Co., Ltd.
About This Product
DC24V type can be controlled by proportional output (analog output) damper etc.
■ Features
・ By controlling the ventilation device, the number of CO2 concentrations is grasped and the indoor air quality is kept clean.
・ Measure and display the CO2 concentration in the room, "visualize" the CO2 concentration, and automatically control ventilation
・ Significant reduction in energy -saving electricity bills due to proper ventilation control
・ Improvement of work, prevention of drowsiness and health damage and improvement of learning environment
・ High -precision optical type NDIR dual beam sensor, CO2 concentration correction (calibration) function
Compatible with the Ministry of Economy, Trade and Industry's "Guidelines on Selection of Carbon Dioxial Calmary Measuring Instruments", 2014 Tokyo Trial Certified Certified System Certified Product, 2013 Machida City Trial Introduction System Certified Product Certified Product
■ Where to use
Classroom, office, public space, hospitals, greenhouse / plant factories
■ Judgment criteria
・ 1,000PPM: preferred and healthy outdoor level. Especially 800 to 1,000 is a healthy CO2 level that considers energy saving
・ 1,000 to 2,500: You may feel drowsy and feel discomfort or smell.
・ 2,500 ~ 5,000: Health damage is expected after a long time.
■ Standard value
・ ~ 1,000PPM: Recommended value of the American Heating Cooling Air Conditions Society, Building satellite Management Law (including hospitals and other facilities)
・ 1,000-1,500: School environmental hygiene standards
■ outer dimensions
Width 120mm x height 120mm x thickness 28mm
