Single-gas fixed detector
Single-gas fixed detector










Fixed Gas Detector · Bosean
Fixed point detector with natural-diffusion sampling, LCD display, RS485 Modbus RTU and 4–20 mA outputs. Sensor modules are selected for the target gas.
The installed sensor package, measurement ranges and available options depend on the ordered configuration. Confirm the final specification before application.
BH-DX103 · Fixed Gas Detector
Fixed point detector with natural-diffusion sampling, LCD display, RS485 Modbus RTU and 4–20 mA outputs. Sensor modules are selected for the target gas.
The model should be selected against the target measurement, operating environment and required system interface. Where a product family offers multiple sensors or hardware versions, the ordered configuration—not the full option list—defines the instrument supplied.

06 / Common Questions
The product information identifies Single gas; sensor-dependent. The exact channels and ranges depend on the ordered configuration and should be confirmed against the current datasheet.
Start with the target gas or parameter, required measuring range, installation environment and output requirements. Confirm the final sensor and hardware configuration with the supplier.
No. Options shown for a model family should not be assumed to be installed simultaneously. The quotation and datasheet should identify the exact supplied configuration.
Review the current datasheet, user manual, wiring or mounting information and any certificate required for the intended site.
