CO2 Monitor------Ultra low-Cost by IR-Soc Technology.

By using the IR-SoC (Infrared System on the Chip) technology . ZyAura, a world class leader and supplier for the IR sensor technology and measurement devices ,has developed the ultra low-cost CO2 Monitor. It can be widely used in the array of scientific, professional, academic, and personal applications.

In recent years, Indoor air quality (IAQ) has become of a concern for the customers looking for the better ventilation in their building. The poor ventilated building can easily affect the people who inhabit them. There are a few notable symptoms, such as headaches and stuffiness.

The owner of the business are beginning to realize that the poor air condition has affects the performance for the employees. And the housewife also realized that the poor air quality is unhealthy for their family member. But this can be prevented.

This CO2 monitor has the alarm level that can be set between 400 -10,000ppm by the user. The ventilation system runs due to the amount of the CO2 concentration in the air. When the level is higher than the setting parameter, it will remind the user to take care of the air quality.

Besides this function, it has many features which can be handle easily. The Data logger Mode can store the data in the past 24 hours. The Alti Mode can adjust the elevation when necessary. The Outside Mode to modify the outside CO2 concentration to define the current ventilation rate. The Max/Min Mode can provide the recorded Data for the last using. The Rcfs Mode is to recover the factory setting to get the accurate reading when it has been used over 12 months. It can also display the ambient temperature when you use it .For this excellent model. We are willing to share the specification with you:
