How to Specify the BH-DX103
Define the measurement task before choosing a product configuration.
- Target measurement: Confirm the gas or environmental parameter and whether more than one channel is required.
- Range and performance: Match the measuring range, resolution, accuracy and response requirements to the application.
- Installation environment: Review temperature, humidity, dust, water exposure, mounting and hazardous-area requirements.
- System integration: Confirm power, analog or digital outputs, communication protocol and alarm interfaces.
- Maintenance: Check calibration, bump-test, sensor replacement and service requirements in the current manual.
06 / Common Questions
Frequently Asked Questions
What does the BH-DX103 measure?
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.
Which version of the BH-DX103 should I select?
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.
Are all listed options included in one standard unit?
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.
What documents should be checked before installation?
Review the current datasheet, user manual, wiring or mounting information and any certificate required for the intended site.
