Detection and analysis apparatus

Tender description

Maynooth University is seeking tenders for the supply and delivery of a range of environmental sensors that will be deployed at benchmark test sites to support the research activities to improve knowledge and understanding of land use activity. The goods required comprise of: Lot 1: 2 x Automated Soil Gas Flux Chamber System; Lot 2: 8 x Soil Moisture Monitoring System; Lot 3: 2 x Two-Level Weather Station; Lot 4: 2 x Greenhouse Gas (GHG) Eddy Covariance System. Two (2) automated soil gas flux chamber system are required to automatically acquire, process, store and transmit data collected from in-field environments. The equipment should be ruggedised and weatherproof. The instruments should have the capability to communicate in (near) real time (e.g. mobile, WiFi enabled) and be suitable for long term deployment at remote sites, with minimum maintenance required. The ability to remote troubleshoot issues would be beneficial. Eight (8) x soil moisture monitoring systems are required to provide suitable systems for monitoring and measuring soil moisture (to a depth of 1 metre) and soil temperature and associated equipment. The instruments should have the capability to communicate in (near) real time (e.g. mobile, WiFi enabled) and be suitable for long term deployment at remote sites, with minimum maintenance required. Two (2) x two-level weather stations are required as meteorological monitoring systems, to obtain measurements at two levels (2 m and 10 m) deployed on a ~10 metre tall tower and associated cabling and data logging equipment. Their function is to automatically acquire, process, store and transmit meteorological data at research grade accuracies. Should have the capability to communicate in (near) real time (e.g. mobile, WiFi enabled). Two (2) Eddy Covariance (EC) system are required, consisting of the full sensor infrastructure (hardware and software) needed for the correct measurement and calculation of terrestrial carbon dioxide (CO2) and water (H2O) fluxes and, optionally, methane (CH4) and nitrous oxide (N2O), using the EC method. The instruments should have the capability to communicate in (near) real time (e.g. mobile, WiFi enabled).
