The standard monitor has below two models

1.Carbon dioxide(CO₂)+CO₂average +Temperature+ Humidity (Model:DPM-1003)

2.Carbon dioxide(CO₂)+CO₂average +VOC +Temperature+ Humidity (Model:DPM-1004)

Two unique extended functions (Optional)

1.RF short-distance wireless transmission & reception

2.USB data logging

The product can be worked together with our wireless controller to control a ventilator, air cleaning device, or humidity device, based on the real-time measurements and the presetting values of the monitor.
