The Vaisala CARBOCAP® Carbon Dioxide Probe GMP343 is an accurate and rugged probe-type instrument for ecological measurements. Typical applications include CO2 soil respiration, ambient CO2 monitoring, plant growth chambers, and OEM applications.
♦ Excellent accuracy and stability
♦ Vaisala CARBOCAP® Sensor, a silicon-based non-dispersive infrared (NDIR) sensor
♦ A single-beam, dualwavelength CO² measurement with no moving parts
♦ Compensation options for temperature, pressure, humidity and oxygen
♦ Low power consumption and heat emission
♦ Designed for outdoor use
♦ Compact and lightweight
The GMP343 can output both numerically filtered and raw measurement data and it can also compensate the measurement with an internal temperature measurement and user-set relative humidity, pressure and oxygen values.
In combination with an MI70 indicator, the GMP343 provides a tool for accurate in-situ measurement. Th MI70 can be used as a display, communication and data logging device.
Each GMP343 is calibrated using ±0.5 % accurate gases at 0 ppm, 200 ppm, 370 ppm, 600 ppm, 1000 ppm, 4000 ppm and 2 %. Calibration is also done at temperature points of -30 °C, 0 °C, 25 °C and 50 °C. If needed, the customer can recalibrate the instrument using the multipoint calibration (MPC) feature allowing up to 8 user-defined calibration points.
