Manual

The LCi is our smallest, lightest and most user friendly Portable Photosynthesis Measurement System ever. It allows access to field sites previously unconsidered using a conventional IRGA system.

The LCi is less than half the weight and size of most traditional systems. Full functionality, flow control and data logging are all contained within the ultra compact LCi console.

Powered by a small 12 V rechargeable battery and incorporating the latest in low power consumption technology, the LCi will operate fully for up to 10 hours from a single charge. In the field, the LCi can be used with the conventional shoulder strap or worn on a belt. Designed for harsh field conditions, the LCi maintains optimal experimental performance even in high humidity or dusty environments.
