SoilBox-FGAThe FGA consists of a CO2/O2 analyzer host and a SoilBox soil respiration chamber. The FGA is equipped with a CO2 analyzer, O2 analyzer, gas sampling unit, and data collector, which can be used to measure and analyze animal respiration, root respiration, soil respiration, and soil carbon flux. The instrument can be connected to an external methane analyzer, temperature sensor, or other environmental factor sensors.

Configuration plan:

1. Basic configuration: including PGA host (equipped with 1 soil temperature sensor) and soil breathing room. The breathing room has transparent and non transparent breathing rooms for optional use (the same below). The transparent breathing room is equipped with temperature, humidity, and PAR sensors, while the non transparent breathing room can be equipped with built-in temperature, humidity, and solar radiation sensors.

2. Soil moisture measurement sensor or TRIME-PICO soil moisture measurement sensor can be optionally selected based on the basic configuration

3. Optional methane analyzer (external) for simultaneous measurement of CO2/CH4 flux and O2

4. Optional Soil Animal Breathing Room, Laboratory Soil Breathing Room, Root System Breathing Room

The specific performance indicators are as follows:

1. Gas analyzer type: Oxygen: Fuel cell technology; Carbon dioxide: colorless dispersive dual wavelength infrared gas analyzer

2.Range: O2: 0-100%, CO: 2-5%

3.Accuracy: O2: 0.1%, CO2: 1%

4.Resolution: O2: 0.0001%, CO2: 0.0001% -0.01% (depending on concentration range)

5.Drift: O2:<0.02% per hour at constant temperature; CO2:<0.001% per hour;

6.Methane analyzer (optional, external): Dual wavelength infrared technology, pressure compensation,Measurement range 0-10%, resolution 1ppmAccuracy of 1%,Airflow of 5-2000ml/minute, noise less than 3ppm, 24-hour drift less than 0.01%, equipped with a two-line text and digital LCD display screen, backlit, capable of displaying CH simultaneously₄Content and pressure, 16 bit resolution, with digital filtering (noise); Size 30x25x10cm, weight approximately 4.5kg

7.Gas sampling unit: including a pump, needle valve (controlling the airflow in and out of the pump body), and gas flow meter (0-2000ml/m); Diaphragm pump, roller motor, flow rate 10-1700mL/min; Thermal bridge flowmeter with a resolution of 0.1mL/min (flow rate 0-99.9mL/min), 1mL/min (when greater than 100mL/min), and an accuracy of 2%; Analog output 12 bits

8.Airflow control: Microelectronic thermal feedback system (true scientific research no longer uses rotor flow meters, as glass tubes are easily affected by surrounding temperature and pressure, so papers using rotor flow meters cannot be published in international journals), airflow control actually connects the airflow pump and flow meter through a precision feedback loop system (microcomputer control), while providing high-precision needle valves;

9.Soil temperature sensor (optional): Thermistor principle, measurement range -5-60 ℃, resolution 0.001 ℃, absolute accuracy 0.2 ℃, BNC connection, probe diameter 2.5mm;

10.Display: 4goLCDMonitor, real-time synchronous display of CO2 concentration, O2 concentration, flow rate, etc;

11.Signal input: 2 BNC ports, can be connected to analog voltage signal sensors or temperature sensors

12.Signal output: BNC connector, analog signal output, O2, CO2, And 2 customizations

13.Digital output: RS-232

14.Built in memory: 8190 data points.

15.Data recording interval: 0.1 seconds to 1 hour, user-defined

16.Software: Windows version software, capable of real-time display of data curves, data downloads, data analysis, etc

17.Power supply: 12-15VDC, 50-500mA, equipped with AC adapter

18.Operating temperature: 0 to 50 ℃, no condensation

19.Size: 31cm × 18cm × 31cm

20.Weight: 5kg

21.SoilboxSoil breathing chamber: The standard configuration is an aluminum alloy silver white or transparent breathing chamber with an inner diameter of 20cm and a height of 20cm. It has a low-temperature chamber effect and can be equipped with built-in temperature and humidity sensors and PAR or solar radiation sensors.
