Our fixed odor detection instrument integrates high-precision sensors to ensure data accuracy. The error detection feature continuously calibrates the device for reliable real-time measurements. The range drift detection function provides consistent results during repeated measurements of the same gas concentration, while zero-point drift detection ensures accurate readings in the absence of gas. With rapid response capability, the device quickly alarms and transmits data during gas leaks. It also features automatic self-check to maintain optimal performance.
