CFLUX1 Toprak CO2 Çıkışı Otomatik İzleme Sistemi

CFLUX-1 Automated Soil CO2 Flux System

• Fully automatic, programmable & stand-alone operation

• Integral CO2 & H2O infrared gas analyzers

• WiFi for setup & remote monitoring from desktop & mobile devices

• Easy installation & setup

• Optional sensors for soil moisture & temperature

Technical Specifications

Gas Analysis Unit Analysis Method Two non-dispersive infrared, configured as an absolute absorptiometer with microprocessor control of linearization for both CO2 and H2O.

All readings are automatically corrected for temperature, pressure and foreign gas broadening.

CO2 Measurement Range 0-2000 µmol mol-1 (Standard)

Precision: 1 µmol mol-1 For high CO2 environments the system can be calibrated up to 30000 ppm. H2O Range 0-75 mb • Precision: 0.1 mb Pressure Compensation 80-115 kPa Range Absolute Accuracy < 1% of span concentration over the calibrated range but limited by the accuracy of the calibration mixture Linearity < 1% throughout the range Stability Auto-Zero at regular intervals corrects for sample cell contamination, source and detector aging and changes in electronics. Calibration User-programmable calibration (If required) Warm-up Time Approximately 15 minutes Sampling Rate 10 Hz Sampling Pump Integral pump for sample (analysis) air • Range: 200-500 cc/min An internal electronic flow sensor monitors flow rate. Air Temperature Sensor • Range: -20 °C to +50 °C • Accuracy: +/- 0.5 °C at 25 °C Environmental Sensor For use with commercially available sensors Inputs (soil moisture, soil temperature. etc.) • One analog input (0-1V) • One SDI-12 input Data Storage (USB) USB flash drive port for date storage WiFi For user setup/monitoring and connectivity to internet Power 7-16 VDC (User supplied) Power Consumption Warm up: 15W (12V at 1.2A) Normal operation: 7.2W (12V at 0.6A) Enclosure Hinged, rugged, polycarbonate enclosure Operating Temperature -20 to +50 °C, non-condensing Dimensions 60.75 cm (L) x 30 cm (H) x 30 cm (W) Weight 8.5 kg Soil Respiration Chamber Volume 2500 cm3 Exposed Soil Area 336 cm2 Soil Collar (ID) 20.7 cm (8") Diameter
