Gas Analysis FAQ
Q: How often do gas sensors in continuous monitors need calibration?
A: Calibration frequency depends on the sensor type, target gas, and operating environment. While electrochemical sensors may require quarterly checks, advanced NDIR or laser-based sensors from Weshine can often operate for 6-12 months between calibrations. Our systems include reminder alerts and a streamlined calibration process to ensure ongoing accuracy.
Q: Can one monitor handle a mixture of gases without interference?
A: This is a common challenge. Basic sensors can cross-react. Weshine monitors utilize sensor arrays with proprietary software algorithms that actively compensate for known interferents. For complex mixtures, we offer Gas Analysis systems with integrated gas chromatograph modules to separate and quantify individual components precisely.
Q: What is the biggest threat to the longevity of a continuous gas monitor?
A: Sensor poisoning or degradation from exposure to extreme conditions like high humidity, particulates, or incompatible chemicals is the primary threat. Weshine designs incorporate robust filters, protective membranes, and environmental conditioning to shield the core sensor, significantly extending its operational life and reliability.
