Frequently Asked Questions
Q: What does “LEL” mean in the measuring range?
A: LEL means Lower Explosive Limit. 100% LEL is the lowest concentration of gas in air that can create an explosion.
Q: Can this detector be used for ethylene gas?
A: Yes, the Searchpoint Optima Plus can be calibrated for ethylene. Note that accuracy specifications differ slightly from methane.
Q: How often does the detector need calibration?
A: Recommended calibration interval is typically every 6-12 months, depending on application, regulations, and environmental conditions.
Q: What is the difference between IP66 and IP67 ratings?
A: IP66 protects against powerful water jets. IP67 protects against temporary immersion in water up to 1 meter for 30 minutes. This unit meets both.
Q: From field experience, what affects sensor performance most?
A> Window contamination is the main issue. Keep the optical window clean. Consider protective covers or scheduled cleaning in dirty environments.
