-40ºC to +65ºC/ -40ºF to +149ºF, (IR: -20ºC to +50ºC/ -4ºF to +122ºF).
Note: The detector display may become illegible at temperatures below -40°C, but the detector continues its gas monitoring
function. The display is not damaged and recovers when the temperature rises back above -20 °C.

, Toxic and Methane/Carbon Dioxide IR with calibration cup (S3KCAL).
Response time (T90) may increase when operating in lower 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. Flammable CAT
and 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 and H2 EC sensors, 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.
