First, measurement parameters (function) :
Accurately measure the temperature and humidity of the soil, as well as the CO2 concentration, temperature, and moisture humidity of the gas in a certain volume
Second, the main application:
Environmental gas monitoring, soil respiration, carbon flux, etc
Three, the main technical indicators:
1. Integrated breathing chamber and analyzer: stainless steel, pollution-free soil.
Measuring area: 314 (cm2);
Measurement volume: 2900 (cm3);
Temperature range: -30~80 degrees Celsius;
Humidity range: 0-100RH;
Dimensions: Length 280* width 280* height 500mm
Net weight: 4kg;
2. Analyzer: non-dispersive infrared gas analyzer, with automatic temperature, pressure compensation function.
1) CO2 measurement range: 0-1000ppm, 0-2000ppm, 0-5000ppm, 0-10000ppm, 0-20000ppm, 0-30000ppm, 0-50000ppm, 0-100000ppm (10%), the above range is optional.
2) Accuracy: 1000ppm±0.1%, 2000ppm±0.1%, 5000ppm±0.5%.
3) HO2 measurement range: 0-99%.
4) Pressure compensation range: 80-115kPa.
5) Stability: Regular automatic zeroing to correct errors caused by sample chamber contamination, light source and monitor aging, with amplifier gain function.
6) Gas measuring body flow rate range: 100-1000ml min-1
3. Soil sensor: synchronous measurement, soil moisture, soil salt, soil temperature; Sensor instantaneous; Corresponding no calibration required; Compact, durable and maintenance-free, it measures dielectric permanence, soil moisture and soil conductivity.
