Please note: the image may differ from actual product.

As it can be used in industries such as oil and gas, steel, waste and wastewater and chemicals, the polycarbonate housing is tough and IP65-rated.  This makes it resistant to impact and dust and water ingress.

Datalogging and event logging are available with the Crowcon Gasman.  This allows 900 hours to be stored at 1-minute intervals (54,000 logs), as well as more than 4800 events.

The Crowcon single gas monitor offers a number of alerts to the presence of gas.  This includes a vibrating alarm, flashing LCD alarm and an audible 95dB alarm.   It will also let the user know when the unit is 30 days away from needing recalibrated.
