| Roxy-8 Specifications: |
| Technology: Paramagnetic oxygen analyzer, auto-calibrating, temperature and barometric pressure compensated |
| Channels: Eight, sequentially selected; separate setpoints for each; any channels(s) can be deselected by operator |
Range: Oxygen: 0 - 100%; Automatic selection of nitrogen or oxygen as control gas for each chamber
|
| Accuracy: At constant temperature, accuracy better than 0.1% of full scale, 0 - 100% oxygen; Barometric pressure accuracy better than 0.05% of full scale |
Calibration: Manual or automatic, at user defined intervals. Requires sources of nitrogen and oxygen, normally already required for regulation operation
|
Gas Inlet Pressure: < 25 p.s.i. or < 170 kPa
|
| Gas Inlets: Oxygen and nitrogen (main and backup with automatic switching) |
| Gas Inlet Pressure Meter: 0 - 200 kPa, 1% accuracy, 0.1 kPa resolution, alarmed at user-specified low pressure trigger
|
Sampling flow rate: Nominal 175 ml/minute from built-in pump; flow rate monitored and alarmed
|
| Serial Data Output: Comma delimited ASCII string of all measured parameters |
| Alarms: Settable for tank pressure, sampling flow rate, and power supply voltage; internal audio alarm plus normally closed contact for autodialer etc. |
| Internal A/D Conversion: 24 bits, individual converters for oxygen and pressure |
| User Interface: Intuitive menu system backed by nonvolatile memory of user settings |
| Panel Display: Digital 4-line alphanumeric LCD, simultaneous display of 8 oxygen setpoints and readings |
| Temperature Compensation: Internal to the fuel cell, optimized over 15 – 45 °C range; External optionally uses temperature data (full details supplied on request). |
| 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: 11 - 14VDC (12 VDC nominal), < 1 A. 110VAC or 220VAC adapter supplied |
| Operating Temperature: 5 - 45 degrees C, relative humidity non-condensing |
| Size/Weight: CORRECT PLEASE 13" x 10" x 4" (33 x 25 x 10 cm); less than 10 lbs (4.5 kg) |
