NOTES
Performance figures are taken at 20~25℃;
1. measured using a sample humidity of 50%RH, applicable between 10 and 90% of full scale,
2. measured using test units calibrated at 50% of full scale,
3. measured at 1000cc/min for Methane CAT, 500cc/min for Methane IR with calibration cup (S3KCAL).
Response time (T90) may increase when operating in lower or higher temperature conditions or when gas is introduced with the Weather
Protection accessory (SPXCDWP) fitted. Should it be exposed to other HC then non linear response is expected. For linearised operation
other than Methane contact HA for alternate parts. This calibration enables 100% functional test prior to dispatch.
This calibration does not remove need for calibration & test as part of commissioning at site. For gases other than Methane the unit has
to be calibrated at site using target gas.Data represents typical values, and system conditioning may be required to achieve stated result.
Contact HA for details.
* Extended operating temperature range of -40°C to +65°C (-40°F to +149°F) for all sensor , with an accuracy of +/- 30% of applied gas
from -20°C to -40°C (-4°F to -40°F) and +55°C to +65°C (+131°F to +149°F). Long term operation at this range may cause decline in
sensor performance.
Contact Honeywell Analytics for any additional data or details.

Note: The detector display may become illegible at temperatures below -20°C, but the detector continues its gas monitoring
