Carbon Monoxide Monitor Features

The ISA-34RAL respiratory air line CO monitor/alarm automatically and continuously monitors respiratory air lines for carbon monoxide levels and provides audible and visual alarms when the air line CO concentration rises above a preset limit. When the level of CO in the air passing the sensor increases to the preset value, the equipment alarms and relays activate. The preset calibration level may be as low as 20 PPM.

The equipment operates from either 117 VAC or 12 VDC, at the option of the user, with terminals for either mode of operation located on a barrier strip inside the unit. Due to its electronic voltage regulation, the ISA-34RAL maintains precision gas calibration despite input voltage variations as great as -10% to +20% of rated supply (either AC or DC).
