Overview

  • Fully automatic, programmable & stand-alone operation

  • Integral CO2 & H2O infrared gas analysers

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

  • Easy installation & setup

  • Optional sensors for soil moisture & temperature

Specification

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 Range 80-115 kPa
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.
