Pro CO (Carbon Monoxide) Analyzer with Low Pressure Alarm


Price on request

SKU: 9621.5-LB Categories: ,

The Pro CO Analyzer with Low Pressure Alarm is made for the surface supply working diver that is required to have a carbon monoxide analyzer and low pressure alarm. The Carbon Monoxide Analyzer measures carbon monoxide (CO) levels in gases in the range of 0 to 100 parts per million (ppm). It can be used to measure the CO content in gas mixes that may be contaminated due to the introduction of CO from internal combustion engines or other devices where CO is a byproduct. The low pressure alarm is connected to the volume tank and supplies a loud alarm if the air pressure drops below the set pressure. The Water-Resistant Case includes a Digital Display and controls that are environmentally sealed. The Analyzer uses a Flow Adapter Cap and Flexible tubing to deliver sample gas to the Sensor. Pressurized gases must be regulated to avoid damage to the analyzer.
