Introduction

Overview Specification

ZyAura ZG9 series, featuring an ergonomic design and innovative NDIR technology, is the Handheld Multi Gas detector for the measurement of CO2, CO, PM2.5, PM10, and other indexes to monitor indoor quality. With long-term data storage and RS485 communication interface, ZG9 series provides accurate, reliable measurements is ideal for personal or industrial applications, including office, station, food industry, HVAC, commercial building, or home usage.

Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.
