Frequently Asked Questions
❓
What buttons does the BTYQ-SD3011 leak detector have?
The device is equipped with four buttons: Left, Menu, Power, and Right. These allow users to navigate menus, power the device on/off, and adjust settings easily.
❓
What do the three indicator lights on the device represent?
The three indicator lights represent Normal operation status, Alarm condition (gas detected above threshold), and Fault status (device malfunction or sensor error).
❓
What are the main structural components of the leak detector?
The leak detector mainly consists of five key components: the casing, circuit board, battery, display screen, and sensors. Each plays a critical role in the device's operation and durability.
❓
What working principles does the leak detector use?
The device supports two detection principles: Electrochemical type, which is suitable for detecting toxic gases, and Catalytic Combustion type, which is designed for detecting combustible gases. The appropriate type is selected based on the application scenario.
❓
What is the difference between electrochemical and catalytic combustion detection?
Electrochemical sensors detect gas by measuring electrical signals generated by chemical reactions — ideal for toxic gases like CO or H₂S. Catalytic combustion sensors detect flammable gases such as methane by measuring the heat produced during controlled oxidation on a catalytic bead.
❓
Is the BTYQ-SD3011 suitable for portable field use?
Yes, the BTYQ-SD3011 is designed for portability. Its built-in battery, compact casing, and intuitive button controls make it well-suited for on-site inspections and continuous field monitoring in various industrial environments.
