The solution for measuring harmful gas in greenhouses The MACView ®-Greenhouse Gas Analyser is an extreme sensitive gas measurement device for monitoring harmful gasas in greenhouses. The gas measurement device measures in ambient air NO, NO2, C2H4, CO and CO2 with a very high precision. The MACView ®-Greenhouse GA displays the amount of gas in the range of ppb (Parts Per Billion). This device assist the grower to become more conscious and gives more insight into the amount of harmful gas around crop. The allowable concentrations and time for crop are known as maximum allowed concentrations over time. Monitoring While using CO2 fertilisation in greenhouses, there is a possibility of amassment or pile up of harmful gas. The reason for this pile up is that CO2 is consumed by the crop, and harmful gas is not immediately broke down. A small amount of (harmful) gas which is present in the greenhouse for a relative short period of time, would (normally) not be detrimental for the crop. However, exposing the crop to a minimum of gas for a relative long period of time could damage the crop. This is also dependent of kind of crop, cultivar, age and improving stress conditions like light, temperature, RH etc. around the crop. MEASUREMENT TECHNOLOGY
