| TurboFox Specifications: |
| Technology: Oxygen: Fuel cell, not harmed by moisture, CO2 or particulates; 18-36 month life, user-replaceable. CO2: Non-dispersive dual wavelength IR, gold-plated optical path. Water vapor: Capacitive sensor with porous platinum electrodes |
| Range: Oxygen: 0 - 100% (best accuracy above 1%) or 0 - 105 kPa O2 partial pressure; barometric pressure 30 - 110 kPa; CO2 0 - 10%; Water vapor: 0-99% RH (non-condensing), 0-5000 kPa WVP, 0 - 10 ug/ml WVD |
| Accuracy and Resolution: At constant temperature, accuracy better than 0.2% of full scale, 1 - 100% oxygen, resolution 0.001%O2; Barometric pressure accuracy better than 0.05% of full scale, resolution 0.001 kPa |
| Noise and Drift: Oxygen: At constant temperature, flow rate and oxygen concentration: Noise < 0.003% pk-pk over 20 minutes; Drift < 0.02% over 24 hours. CO2: Noise < 3 ppm pk-pk, drift < 0.002% over 24 hours. Water vapor: At 0% RH, Noise < 0.005%RH, drift < 0.2RH over 24 hours
|
| Response time: Oxygen: < 7 seconds for 10-90% of a step change at a subsampling rate of 200 ml/minute; carbon dioxide < 1 sec; water vapor < 8 sec; all can be substantially reduced during data analysis |
| Flow Rate and Moisture: Effect of flow rate on readings from 20 - 500 ml/minute subsampling rate is negligible; not damaged by moisture; particulates are trapped by built-in filters |
| Barometric Pressure Compensation: Executed in floating-point math; eliminates drift caused by variations in barometric pressure. |
| Analog Outputs: Oxygen (5 ranges, 3 ranges zero-suppressed); Barometric pressure (3 ranges, 2 ranges zero-suppressed); Temperature (3 ranges, 2 ranges zero-suppressed); CO2 (5 ranges); Flow rate (8 ranges): Water vapor pressure/water vapor density (10 ranges); plus User-defined. 0-5V with 16 bit resolution on all outputs |
| Serial Data Output: Comma delimited ASCII string of all measured parameters, standard RS-232 serial, baud rate adjustable from 9600-115200, polled or auto-sent at user definable intervals from 0.1 - 600 seconds |
| Digital Filtration: Adjustable from zero to 50 seconds for 0-63% of a step change, in 0.2 second increments. |
| Internal Data Acquisition: 8 channels -5.12 - +5.12V, 16 bits; 4 channels temperature/resistance voltage (0-5.12V), all 16 bits; 8 digital outputs; two analog outputs (0-5V, 12 bits) |
| User Interface: Intuitive menu system backed by nonvolatile memory of user settings. Single-click spanning at default span settings |
| Panel Displays: Two 2-line alphanumeric LCDs, one 4-line alphanumeric LCD, backlight selectable |
Internal Data Storage: 8000 points, each point comprising all measured parameters
|
| Tubing Fittings: Nickel plated barb fittings for 1/8" (3 mm) i.d. flexible or semi-rigid tubing; other fittings available to special order |
| Power Requirements: 24VDC, 500 mA - 6 A depending on operation. Universal adapter supplied |
| Operating Temperature: 0 - 45 degrees C, relative humidity non-condensing |
Size/Weight: 27" x 20" x 15" (67 x 50 x 37 cm); less than 40 lbs (18 kg); hermetically sealed when closed
