| MA-10 Specifications: |
| Technology: Dual wavelength infrared with gold-plated optical path |
| Range: 0% to 10% CH4 (contact us if you require measurements above 10%; available to special order) |
| Accuracy and Resolution: At constant temperature, accuracy better than 1% of calibrated span, 0 - 10% methane; Resolution to 1 ppm/0.0001% |
| Noise and Drift: At constant temperature, flow rate and CH4 concentration: Noise < 3 ppm pk-pk (5 second digital filtration setting), 10 ppm pk-pk (no filtration) over 20 minutes near zero; Zero drift < 0.01% over 24 hours |
| Flow Rates: 5 - 2000+ ml/min. Effect of flow rate on readings from 20 - 500 ml/minute is negligible; not damaged by non-condensing moisture; particulates are trapped by built-in filter |
| Panel Display: Two line 16 character alphanumeric. Line 1: CH4 concentration to 1 ppm, 0.001% or 0.01%, depending on concentration; or partial pressure of CH4. Line 2: barometric pressure to 0.001 kPa. Display also used for user interface menu system
|
| Voltage Outputs: 0 - 5 Volts for 0 - 100 ppm/10 Pa, to 0 - 20%/kPa methane in eleven ranges, plus separate outputs for optical bench temperature and barometric pressure, 4 ranges each; short circuit protected; 16 bits (up to 1 in 65535) voltage resolution in each range |
| Serial Output: Methane concentration (to 1 ppm), barometric pressure (to 0.001 kPa), and optical bench temperature (to 0.001 deg C) with comma delimiters, updated at user selectable intervals from 0.1 second to 5 minutes |
Temperature Range: Operating, 0 to 45 C, non-condensing relative humidity
|
| Power Requirements: 11 - 15VDC, 300 mA. Universal 90-240VAC to 12VDC power source supplied with unit |
| Size: 13" x 10" x 4" (33 x 25 x 10 cm) |
| Weight: Less than 10 lb (4.5 kg) |
