Common Questions & Answers

Q: What gases can the 2108B2003N detect?
A: This detector monitors all combustible gases and vapors including methane, propane, butane, hydrogen, ethanol, and most hydrocarbon compounds. Factory calibration is typically set to methane equivalent.

Q: How often does the sensor require calibration?
A: Recommended calibration interval is every 6 months under normal operating conditions. Harsh environments or exposure to sensor poisons may require more frequent verification.

Q: Can this detector be used in Class I Division 1 hazardous areas?
A: Yes, the 2108B2003N carries FM, CSA, ATEX, and IECEx certifications for installation in Class I Division 1 and Zone 1 hazardous classified locations.

Q: What is the typical sensor lifespan?
A: Catalytic sensors typically provide 3-5 years of reliable service depending on environmental conditions and exposure to contaminants. Sensor replacement is straightforward with field-replaceable modules.

Q: Does the unit include relay outputs for alarm functions?
A: The 2108B2003N provides 4-20mA analog output. Alarm relay functions are typically handled by the connected control system or separate gas detection controller.
