Everything seems fine but when exceed the co2 level, the fan connected wont turn on. Any solution problem? Thank you

Are you set up correctly ? Out of the box it’s set to add co2 to a greenhouse. So it deactivates the solenoid

Is it possible to get this co2 day and night monitor with eu-plugs?

"Hi, it comes with US plug, we can supply you with the EU plug if you want to purchase it with EU plug. Please contact our customer service representative through Amazon message. Or if your shipping address is in Europe, you may buy the item through the link below: http://www.amazon.it/dp/B08H8BP15N?ref=myi_title_dp

Can you Calibrate co2?

Not sure what you mean by calibrate. Can use it to add co2 or remove co2 depending on what use you have for it. Can set it to whatever range you want.

Muy bien producto

El producto cumple su función venía en su caja lo que no me gustó es que venía solo en una caja sin protección alguna contra golpes en el manejo de la paquetería

Great monitor/controller! Good as the more expensive competitors

This controller works like a charm. Absolutely accurate and it couldn't be easier to set up. Numbers are large so you can see them and the co2 remote detector has a green light so it doesn't disturb light cycle of plants. $100 less than the leading brand and works just as well!

Damn good!!!

This thing works the best out of all of the CO2 controllers. Don’t waste your time buying any other one I did and it was a waste. It’s very accurate and easy to use I highly recommend.
