The ChemDAQ Steri-Trac gas monitoring system provides toxic gas detection and workplace safety. It features a modular design that allows for custom configurations, and a sensor exchange program that reduces operating costs by replacing sensors every 4 months without requiring on-site calibration. The system monitors ethylene oxide, hydrogen peroxide, ozone, and peracetic acid, and provides trend analysis and early warnings via software.

1. ChemDAQ Steri-Trac
Toxic Gas Detection System
ChemDAQ’s Steri‐Trac gas monitoring system
provides the optimal solution for workplace
safety assurance, providing protection from
toxic gases
Sensor Exchange Program for Reduced Operating Costs
KEYBENEFITS
• DAQ software provides trend
analysis and provides early warning
The unique modular design of the Steri-Trac eliminates the need for
in-house calibration. Using the sensor exchange program (SXP) you can
receive a factory calibrated sensor every 4 months which you swap on site
in a matter of seconds.

protection
Steri-trac’s fixed detectors are designed to be used with the DAQ system
to display gas concentrations, trends and exposures. Using a traffic light
LED alarm system, it’s easy to interpret gas exposure in each area.
• Sensor change out reduces downtime
and costs
