This complete CO2 controller and regulation system is one of the best on the market; it consists of the Evolution carbon dioxide controller, the Evolution N.D.I.R. CO2 controller with an Ecotechnics CO2 Regulator.
The new Evolution Controller is the most advanced of its kind and has more features and functionality than any other product on the market.

The controller utilises the latest microprocessor and infrared technology to monitor and control the levels of carbon dioxide in your growing area. The controller can operate with or without the CO2 sensor and can be used either with bottled CO2 gas or with a gas burning CO2 generator. In addition to this the controller can be interfaced to most external thermo/hygrostats for improved environmental control for rooms from 1 m3 to 999m3.

To complete the kit we have the Ecotechnics regulator which is manufactured in the UK from top quality components. It has a fixed flow rate of 0.17ltrs per min and is Ecotechnics standard horticultural regulator.

For 10 Years the Unis controller has provided growers with a cheap simple and very reliable means of enhancing co2 levels. The Ecotechnics Unis Co2 controller has been specifically designed to allow easy co2 enrichment for home growroom and glass house horticulture, our Unique approach to Gas regulator design makes this the simplest system to set up in the world. Just calculate the volume of your growing area in cubic meters and dial it into the Unis controller.
 
Its that simple. No more complex calculations about gas flow rate, pressure, on period / off period timing, just one setting. The latest version of the Unis co2 controller is microprocessor based and has 16 settings from 1 Cubic Meter to 100 Cubic Meters.
