em for measurements of soil gas fluxes in high vegetation and one system for measurements of soil gas fluxes in low vegetation. This procurement consists of two lots with different requirements. All devices will be used in field conditions in Finland over three seasons (spring, summer, fall) for the purposes of forest and agricultural studies. During spring, summer and fall the temperature may drop below freezing point. Therefore, the chambers and equipment must withstand conditions below 0°C. Devices/systems will be used with Luke's existing trace gas analyzers, specifically Licor LI-7810 and LI-7820 and therefore the systems offered must be compatible with them. Devices must also be compatible with other analyzers with or without modifications. The Call for Tenders and the procurement is divided into two (2) lots: LOT 1, HIGH VEGETATION includes: A system including 3 opaque chambers and 3 transparent chambers (The chamber or a combination of offered chambers must be able to measure simultaneously transparent and opaque. If the same chamber can be used for opaque and transparent measurements, the total number of chambers to be included is 3.) for a measurement set-up capable to measure in high vegetation up to 70 cm, 1 multiplexer, 1 datalogger and additional hardware required to form a GHG measuring system with analysers (ana
