Overview
The standard AGH6200 four-gas detector monitors combustible gas as %LEL, oxygen, carbon monoxide and hydrogen sulphide in one portable instrument. It uses diffusion sampling without a built-in pump, with a rechargeable battery and audible, visual and vibration alarms.
Key features
- Simultaneous LEL, O2, CO and H2S monitoring.
- Diffusion sampling without an internal pump.
- Rechargeable battery and protective PC/TPU housing.
- Audible, LED and vibration alarm indications.
- Optional external sampling system, subject to compatibility and application requirements.
Applications and selection
For industrial maintenance, utilities, wastewater inspections and plant walk-throughs where these four measurements match the site assessment. This standard configuration does not measure ammonia, sulphur dioxide, nitrogen dioxide or carbon dioxide. For remote sampling during an entry assessment, specify a suitable pump, probe and hose system rather than treating the diffusion detector as a pumped instrument.

Standards and compliance
Match the approval marking and certificate scope to the exact supplied model and gas configuration before hazardous-area use. Follow the operating instructions and site procedures for sampling, calibration and alarm settings. This listing is not the AGH6200F fire-service version.
Included and optional accessories
One AGH6200 with the LEL / O2 / CO / H2S configuration. Confirm the charger and packing list when ordering. An external sampling system and calibration cap are optional and must be selected for compatibility. Calibration gas, regulator and accredited calibration are not included unless expressly quoted.
