Gas Monitoring Systems

Exposure to gases and vapors such as Ethylene Oxide (EtO), Hydrogen Peroxide (H2O2) and Peracetic Acid (PAA) can pose significant risks to workers. Oftentimes workers do not know they are being exposed unless a gas/vapor monitoring system is in place. Whether your needs are more suited toward portable monitoring or a fixed, water-resistant unit, we have a range of monitoring solutions to meet the requirements of your environment.

Sensor Module

The heart of ChemDAQ monitoring systems, the ChemDAQ sensor modules feature excellent performance as well as ChemDAQ’s proprietary Spot-On™ filter technology to reduce cross interference and precisely measure gas vapor levels where applicable (e.g. ​PAAand EtO). The sensors come in two main configurations, the Steri-​Trac® sensor module and the E-Cell® sensor module. 




E-Cell Sensor

ChemDAQ’s E-Cell sensor is used to precisely measure gas/vapor levels for PAA and H2O2. Unlike other suppliers, ChemDAQ’s E-Cell sensors are calibrated with PAA and H2O2 test gas to ensure top safety and performance.

Steri-Trac® Sensor

ChemDAQ’s Steri-Trac Sensor is used to monitor EtO, Oxygen (O2) and Lower Explosive Limit (LEL) and is available for intrinsically safe applications. The Steri-Trac sensors communicate via RS-485 output and so can be used over long distances.

Portable Monitoring

Data Acquisition System (DAQ®)

ChemDAQ’s DAQ is an area monitoring and archival computer software solution. The DAQ can sync and centralize data from up to 32 monitoring locations simultaneously; compare all exposure data to occupational exposure limits; and provide historic reporting for each monitoring point.

Remote Display

Remote displays added to ChemDAQ monitors increase safety by warning employees of hazardous conditions before they enter the area. Display a single reading from a specific space on this easy-to-install display.

Remote Video Display

Remote video displays are an extension of your DAQ. The user can choose to highlight certain areas from their DAQ to display on this single, easy-to-read monitor.
