CI-340 Handheld Photosynthesis System

The CID CI-340 is versatile handheld Photosynthesis system. Designed for the measurement of ambient photosynthetic rate, the CI-340 includes:

• infrared gas analyser
• leaf chamber (default LC-1)
• PAR Sensor
• infrared temperature sensor
• soda lime and silica gel tubes
• spare part kit
• rechargeable battery and charger
• USB Cable
• communication software, operation manual and instrument case

Accessories for measuring different leaves and soil CO2 flux are available, as are control modules to regulate the sampling environment.
