The PS241 is a compact and user-friendly four-gas portable monitor that combines rugged construction, advanced technology, and reliable performance. Designed for demanding industrial environments, it provides continuous monitoring of multiple gas hazards while maintaining ease of use and maintenance.
Lightweight, water-resistant, and certified to multiple international and regional standards, the PS241 is suitable for a wide range of safety applications. It has been specifically engineered to simplify user maintenance, including support for fully automatic calibration stations to enhance compliance management.
The PS241 simultaneously monitors four critical gases commonly encountered in industrial environments:
| Gas Type | Parameter Measured |
|---|---|
| Combustible Gases | LEL (Lower Explosive Limit) |
| Oxygen | O2 |
| Hydrogen Sulfide | H2S |
| Carbon Monoxide | CO |
The PS241 provides comprehensive user protection through multiple alarm methods, ensuring that gas hazards are immediately recognised in various working environments.
The PS241 features integrated datalogging functionality capable of storing up to six months of monitoring information. This assists with incident investigations, compliance reporting, and long-term exposure assessments.
Engineered with user maintenance in mind, the PS241 supports simple servicing procedures and optional field calibration capabilities. Compatibility with automatic calibration stations further streamlines compliance processes and minimises operational downtime.
Built to withstand challenging industrial environments, the PS241 combines durable construction with water resistance to ensure dependable performance in demanding applications.
Coloured protective rubber boots are available in seven different colours, enabling easy identification of devices used across multiple sites, departments, or applications.
