Gas detectors for confined space entry

For confined space entry, four gases are usually checked: oxygen, the lower explosive limit (LEL), carbon monoxide and hydrogen sulfide. The portable detector goes into the field before and during entry.

Terra-IL imports four-gas detectors and quotes by model. The instrument should be bump tested to the manufacturer's instructions before work.

Calibration in the lab or on site, with a suitable calibration gas. The calibration page is in the Service menu.
