CO2 / H2O Analyzer

LI-870

The LI-870 CO2/H2Analyzer is a versatile analyzer for publication quality data that is simple to deploy, use, and maintain. A combination of precision and stability alongside a rugged and fieldable design makes it ideal for survey and long-term research focused on fluxes of soil CO2.

Features

LI-870 Advantages

The LI-870 delivers rapid CO2 flux measurements with great precision while being light enough (2.31 kg) to carry all day without wearing you out. The LI-870 maintains that same speed and precision even when tasked with making long-term measurements in harsh conditions.

The LI-870 has low power requirements (5W average with pump after warmup) and is powered by the Smart Chamber for survey measurements or the LI-8250 Multiplexer in a long-term system. The weatherproof case houses the weather, dust, and splash resistant components with a user-serviceable optical bench that does not require factory recalibration.
