Default output signal?

Instruments are primarily 4–20 mA; relay/HART/BLE/surge follow configuration digits.

Where are datasheet/manual downloads?

Hub and SKU pages link CN/EN datasheet and manual PDFs; certs are blurred thumbs only.

Where to order accessories and spares?

See the Parts family (price list §5.2/§5.3): cal cap, wand, smart sensors, housings/PCBs, etc.

Any mounting orientation / cable-entry notes?

Install per the manual; gland size follows configuration digits; orient the sensor to avoid flooding and direct impact.

Is the sensor on D06A-0420-100 hot-swappable? What does it measure?

Yes — EC smart cartridges are hot-swappable. This SKU: gas H₂S, range —.
