1. Product Overview

Model: RAD-0502 

CO2 Controller for Grow Rooms

Thank you for selecting the 

RAD-0502 CO2 Controller for Grow Rooms

, which is designed to 

regulate CO2 levels and allows growers to set high/low targets to maximize plant yields 
and profitability. 

The 

CO2 Controlle

r for Grow Rooms

 

uses a dual beam NDIR technology to

 

accurately 

measure CO2 concentrations up to 3,000ppm.  With a built-in temperature measurement 
and  photo sensor, the controller can turn off relays during dark periods to save Carbon 
Dioxide (during green house mode). Furthermore, the CO2 grow controller is an ideal solution 
for many growers who utilize the device across indoor greenhouses, cultivation centers, 
hydroponic rooms, or anywhere regulated CO2 levels are important for plant growth. 

Accurate CO2 control for small to large sized indoor grow facilities

Control 2 zones with 2 sensors

Customizable CO2 set points for high and low target levels

Dual beam NDIR technology accurately measures CO2 concentrations 0-3,000ppm

Built-in temperature, humidity, and light

Relay output can automatically control CO2 generator or compressed CO2 tanks

Versatile modes for greenhouse or HVAC
