CO2 : CAP CO2 PPM Monitor PPM-1C

Gardeners, you will love the accuracy and features of the CO2 PPM Monitor. This unit measures the level of CO2 in an indoor garden from 0-5000 PPM (parts-per-million) and displays the readings on a digital readout. This isn't just a monitor; you will get the most for your money when you use it with our 2 Timer CO2 Controller, 4 Timer CO2 Controller or the Complete Greenhouse Controller. When connected any of these units, the Monitor will tell the controllers to produce more CO2 only when necessary. You can enter the exact level of CO2 required and the Monitor will monitor the levels and command an attached unit to produce more if levels fall.The CO2 PPM Monitor is great by itself for CO2 monitoring but even better when paired with Controller unit to maintain ideal CO2 levels. Monitor will work with 120 volt CO2 valve or generator. Unit carries a 3-year warranty
