Presentation

The LCpro+ provides full automatic and independent control of the environmental conditions within the plant leaf chamber. Utilizing the latest microclimate management technology, automatic control of parameters is achieved both above and below ambient conditions. Gas control is user selectable to either the reference or analysis gas streams.

The LCpro+ offers all the facilities and features required by the world’s leading plant science researchers in the most portable format available. The LCpro+ is the smallest, lightest and most user friendly IRGA with microclimate control ever developed.

Featuring new miniaturized infrared gas analyzer and surface mount technology, the LCpro+ is at 8.8 lbs, less than half the weight and size of conventional systems offering microclimate control. Full programmability, flow control and unlimited data storage are contained within the compact LCpro+ console.
