Device Overview
Thank you for selecting ZGW01 desktop & magnetic adhesion CO
2
monitor. ZGW01 CO
2
monitor is a smart, compact and easy-to-use device.
In addition to measuring the CO
2
concentration, ZGW01 can also measure the ambient temperature and the relative humidity
(CO
2
+
Temp.
+
RH)
. This device is developed to detect the presence of CO
2
in ambient air and helps people to take care of Indoor Air Quality.
ZGW01 can be widely used in the office building, school, exhibition hall, shopping mall, meeting room, fitness center, restaurant and other
public places where personal comfort and healthy are important.
Features:
□
V Dual Beam NDIR (Non-Dispersive-Infrared) technology is being used to measure CO
2
concentration and improve the long term stability.
□
V The Large LCD clearly displays the CO
2
concentration, temperature (option), relative humidity (option).
□
V 3-Color LED light (green / yellow / red) gradually changes with CO
2
concentration.
Warnings:
□
V Please take off the AC power adapter and store it well when this CO
2
monitor left idle for a long time.
□
V This CO
2
monitor is for home use, not suitable for certifying the test results.
