Frequently asked questions
Does the ZAQ620 measure wind or rainfall?+
No. The ZAQ620 covers temperature, humidity, CO, SO2, NO2, O3, PM2.5 and PM10 only, without wind, rainfall or noise sensing.
What is the operating temperature range of the ZAQ620?+
-40 to 85°C, wider on the low end than the -50°C spec on some other ZAQ stations.
How compact is the ZAQ620?+
It measures Ø110 mm by 242 mm in height and weighs 1.2 kg, the smallest and lightest station in the outdoor range.
What sensor technologies does the ZAQ620 use?+
Solid-state electrochemistry for gases, laser scattering for particulates, and digital MEMS for temperature and humidity.
