NOTES
Performance figures are taken at 20-25°C;
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. Methane IR
sensor is calibrated and linearised only for Methane. Should it be exposed to other HC then non linear response is expected. For linearised operation other than Methane contact HA for alternate
parts.
Methane IR is calibrated at the factory 50%LEL Methane (2.5%Vol). 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 except for IR, 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.

Operating Temperature -40ºC to +65ºC/ -40ºF to +149ºF, (IR: -20ºC to +50ºC/ -4ºF to +122ºF)
Note: The detector display may become illegible at temperatures below -20°C, but the detector continues its gas monitoring
function. The display is not damaged and recovers when the temperature rises back above -20 °C.
Operating Humidity Continuous 20-90%RH (non condensing), Intermittent 10-99%RH (non condensing)
Operating Pressure 90-110kPa
Storage Conditions -25°C to +65°C (-13°F to +149°F)
