SPECIFICATION:
Analysis Method Non-dispersive infrared, configured as an absolute
absorptiometer with microprocessor control of
linearization
CO2
Measurement Ranges 0-1000 ppm (µmol mol-1)
0-2000 ppm (µmol mol-1)
Please specify at time of order 0-5000 ppm (µmol mol-1)
0-10000 ppm (µmol mol-1)
0-20000 ppm (µmol mol-1)
0-30000 ppm (µmol mol-1)
0-50000 ppm (µmol mol-1)
0-100000 ppm (µmol mol-1)
Readings are automatically corrected for
temperature and pressure.
Pressure Compensation Range: 55–115 kPa
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. Sample data is averaged and output every
1.0 seconds.
Sampling Pump: Integral air sampling pump. Pump can be
programmed for both dynamic and static sampling.
Gas Flow Rate: 200-500 cc/min (280-340 cc/min is optimal). An
internal electronic flow sensor monitors flow rate.
Terminal Block 10 pin terminal block for system inputs and outputs
Analog Output 0–2.5V (CO2
range selectable)
Digital Output USB
Environmental Sensor 2 inputs available for use with external chambers
Inputs and environmental sensors
Alarm Visual and audible alarm/warnings. 2 relay contacts
(Alarm1 and Alarm2)
Data Storage (USB) USB Flash Drive port for data storage in multiple
formats
Mini USB For connection to external PC
Touch Display 2.7” electronic paper touch display with 264 x 176
pixel resolution
Power Internal, rechargeable 7.4V, 8.7 Ah Li-Ion battery
provides up to 16 hours of continuous use.
Battery life will be reduced if used with external
accessories/sensors.
