Range: Many ranges are available. Some common ranges are shown above. Consult Thermco Sales Engineer for details.

Accuracy
  • ±0.3% of minor component absolute over range of 0-10%, all ranges.
  • ±0.5% of minor component absolute over a range of 10.1% to 30.0% all ranges.
  • ±1.0% of minor component absolute over a range of 30.1% to 60.0% all ranges.
  • ±2.0% of minor component absolute over a range of 60.1% to 100.0% all ranges except CO2 in Ar, which has an accuracy of ±8.0%
  • Example: For a 25% CO2 in Ar mixture, the analysis will be between 24.5% and 25.5%
  • This accuracy is valid over a temperature range of 50° to 90°F (10° to 32°C).
Resolution 0.1%
Response Time 95% in 45 seconds for typical gas mixtures
Maximum Drift Zero, ±2% of full range per week; span, ±1% of full range per month. This applies to typical ranges.
Frequency of Calibration Calibration is recommended once per year when used under typical conditions.
Ambient Temperature Limits -10°F to 110°F (-23°C to 43°C)
Utilities Required
  • Reference gas: The background gas in the mixture is required to flow continuously at 0.5 SCFH. This should be a clean, dry, oil free gas. Gas pressure required is 1-150 PSIG
  • Sample gas: The sample gas is required to flow continuously at 1.0 SCFH. This should be a clean, dry, oil free gas. Gas pressure required is 1-150 PSIG, except gases containing H2 are 1-50 PSIG.
  • Power: 104-126 VAC, 50/60 Hz. 1 ampere standard; 204-240 VAC, 50/60 Hz. optional
Output Signal 4-20 mA, proportional to gas analysis range selected. This output is isolated and self-powered with a compliance of 10 VDC.
Alarms Relays Two independent alarm relays, form C, with a rating of 5 amperes at 120/240 VAC (resistive). Note; when the alarm package is specified these alarm relays are utilized in the alarm package circuitry.
Enclosure General purpose indoor panel mount
Weight 44 lbs. (20 kg)
Dimensions 15.5 in (39.4 cm) height, 13.6 in (34.5 cm) width, 10.3 in (26.2 cm) depth
