❓ What gases does the HTC GD-801 detect?

It detects four gases simultaneously: Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Oxygen (O₂), and Combustible gases (Ex – LEL%).

❓ Is the GD-801 suitable for confined space entry?

Yes, the GD-801 is ideal for confined spaces as it features a built-in pump for active sampling, which helps detect gas presence before human entry.

❓ What kind of alarm system does it use?

The GD-801 features a triple alarm system: audible beeper, bright flashing light, and vibration alert, which ensures warnings in noisy or dark environments.

❓ Can I download data from the GD-801?

Yes. The device stores up to 400 gas detection logs and supports data transfer via USB Type-C for graphical review and analysis.

❓ Is the GD-801 explosion-proof or ATEX-rated?

Yes. It is certified with Ex ib IIB T3 Gb explosion-proof compliance, making it safe for use in hazardous industrial areas.

❓ How is this different from diffusion-type detectors?

Unlike diffusion detectors, the GD-801 has a built-in air pump for faster response and more accurate sampling, especially useful in remote or hard-to-reach gas pockets.

❓ What is the battery life of the GD-801?

It comes with a 3000mAh lithium-ion battery, rechargeable via USB Type-C. Battery life depends on usage, typically lasting a full work shift on one charge.
