Features
Detects up to 6 gases (GX-9000) and 4 gases together (GS-9500H).•.
O2, H2S, CO, and CO are widely compatible with gases like NH3, SO2, and CH4. They also have compatibility with most other organic compounds.
USB Type-C for transferring data and synchronizing with smartphones.
The use of a PID sensor can detect VOCs in the 40,000 ppb range.
- Powerful sample-draw pump (≥0.75.
The L/min limit is limited to 45 ms.
A rugged body that is IP66/68 compliant and can withstand water, dust, and 1.5 m of drop-resistant material.
16 international languages are supported by the multilingual LCD screen.
The smart features include automatic calibration reminder, audio confirmation, and snapping.
Li-ion batteries can last up to 35 hours, while the Alkaline batteries may take 15 hours.
