Professional FAQ

Q:How do I keep the detector stable in areas with big temperature swings?
A:Allow airflow around the housing and follow the calibration cycle recommended for cold and hot sites.
Q:What is the best method to verify correct 4–20 mA wiring during startup?
A:Use a field loop calibrator and check the inhibit and warning levels before gas tests.
Q:Can I use this detector near compressors or vibrating plates?
A:Yes. Mount it with a rigid bracket and reduce cable tension to limit vibration impact on electronics.
Q:How often should I recalibrate when I monitor heavy hydrocarbons?
A:Inspect every three months and adjust based on site experience with similar solvents.
Q:Does dust affect the optical chamber?
A:Wipe the front optics lightly and check signal baseline weekly in dusty zones.
