Specifications:
Accuracy and Resolution: At constant temperature, accuracy better than 0.2% of full scale, 1 - 100% oxygen, resolution 0.001% ; Barometric pressure accuracy better than 0.1% of full scale, resolution 0.001 kPa
Barometric Pressure Compensation ( O2) : Executed in floating-point math; eliminates drift caused by variations in barometric pressure
Digital Filtration: Adjustable from zero to 50 seconds for 0-63% of a step change, in 0.2 second increments
Flow Range: 20 - 2000 ml/ minute, measured and/ or controlled via linearized mass flow meter. Accuracy 2% of reading. Temperature and barometric pressure compensation to STP is not required
Four Analog Outputs: Oxygen 3 ranges ( 1 zero-suppressed) ; Barometric pressure 3 ranges ( 2 zero-suppressed) ; CO2 6 ranges; flow rate 7 ranges. Other outputs can be set via the menu system. 0-5V output with 16 bit resolution on all outputs
Internal Data Storage: 8100 data points ( all parameters included) , 0.1 - 600 sec interval, multiple recordings supported, non-volatile, uploadable to PC-compatible computer using included software
Noise and Drift: At constant temperature, flow rate and concentration- O2 noise < 0.004% pk-pk over 20 minutes; Drift < 0.03% over 24 hours. CO2 noise < 5 ppm pk-pk over 20 minutes, drift < 15 ppm over 24 hours
Operating Temperature: 5 - 45 degrees C, relative humidity non-condensing
Panel Display: Digital 4-line alphanumeric LCD, simultaneous display of oxygen ( 0.001 % or 0.001 kPa resolution) , flow rate and barometric pressure ( 0.001 kPa resolution) . CO2, if available, also displayed
Power Requirements: 9 - 24VDC ( 12 VDC nominal) ,
