Description

The Steri-Trac™ 2 Intrinsically Safe Package provides real-time LEL gas monitoring with a monitor, IS barrier, and remote sensor. Designed for hazardous areas, it ensures safety, compliance, and rapid alerts with audible and visual alarms.

The Steri-Trac™ 2 Intrinsically Safe (IS) LEL Monitoring Package is a fixed gas detection solution designed for hazardous environments where flammable gases or vapors may be present. It continuously monitors concentrations near the Lower Explosive Limit (LEL) and is specifically engineered to operate safely in classified or explosion-prone areas. This complete package includes the Steri-Trac™ 2 Monitor, an Intrinsically Safe Barrier Unit that limits energy transfer to the sensor, and a Remote Sensor Mount to detect combustible gases directly at the point of highest risk.

Key Features

• LEL-Specific Monitoring: Designed to detect flammable gases and vapors at concentrations approaching the LEL, the system helps prevent potential ignition risks and ensures compliance with workplace safety requirements.
• Intrinsically Safe Barrier Unit: The included IS Barrier Unit restricts electrical energy entering the hazardous area, making the system safe for Class I, Division 1 or Zone 0 environments, where traditional electronics may pose a spark risk.
• Remote Sensor Mount: Place the gas sensor near valves, sterilizer exhausts, loading docks, or other high-risk areas, while the monitor remains safely accessible in a control room or hallway.
• ChemDAQ SXP™ Sensor Support: The system uses ChemDAQ's Sensor Exchange Program (SXP™) pre-calibrated, hot-swappable sensor modules that reduce downtime and eliminate the need for field calibration.
• Custom Alarms and Real-Time Display: Visual and audible alarms notify personnel when gas levels approach or exceed defined safety limits. Real-time readings, Time-Weighted Average (TWA), and Short-Term Exposure Limit (STEL) data are clearly displayed on the monitor.
• Facility Integration Ready: Outputs include 4–20 mA, Modbus, and dry contact relays for easy integration into building management systems (BMS), alarm networks, or ventilation/abatement controls.

In environments where flammable sterilants or vapors are present, the Steri-Trac™ 2 IS LEL Monitoring Package provides critical safety monitoring without compromising performance or compliance. Whether you're protecting personnel in sterile processing areas or managing chemical risks in an industrial plant, this system offers the accuracy, reliability, and certified safety required to operate confidently in potentially explosive conditions. ChemDAQ's trusted gas monitoring technology, combined with plug-and-play sensor replacement and intuitive alarms, makes this the ideal choice for facilities that demand high standards in safety and compliance.
