Compact Gas Monitor – MUNI MP420


Ensuring Worker Safety in Confined Spaces and Hazardous Locations

In the world of industrial safety, having reliable equipment is paramount. The MUNI MP420 gas monitor is your first line of defense against potential gas hazards in confined spaces and hazardous locations. This compact and lightweight 4-gas detector is designed with worker safety in mind, offering unparalleled protection in a range of industrial settings.

Advanced Detection Technology

The MUNI MP420 is equipped with four standard sensors to detect critical gases including oxygen (O2), combustibles (LEL), carbon monoxide (CO), and hydrogen sulfide (H2S). For specialized applications, alternative sensors are available for low-power infrared methane (CH4), sulfur dioxide (SO2), and hydrogen cyanide (HCN), making it a versatile solution for a variety of gas detection needs.

Robust and Reliable

Packaged in a robust housing with no moving parts, the MUNI MP420 gas detector is built to withstand the rigors of industrial environments. Its IP-68 weather ingress rating ensures reliable performance in even the most challenging conditions.

User-Friendly Operation

Simplicity is key to effective gas detection. The MUNI MP420 features a simple, 2-button operation, making it easy to use with minimal training. Its auto-backlit LCD with large numeric digits and easy-to-navigate menu enhances user experience, ensuring critical information is always at the operator’s fingertips.

Enhanced Safety Features

Safety is our top priority. The MUNI MP420 offers tri-color status indicators for regular self-diagnosis of sensor, battery, and circuit conditions. Wide-angle LED alarms and a 1000-event log ensure that every incident is recorded and visible, enhancing safety protocols.

Long-Lasting Battery Life

With a battery life of 24 hours for the standard 4-gas detector and extended runtime for low-power infrared sensor options, the MUNI MP420 ensures continuous protection throughout the workday. The combination charge adapter and micro-USB PC interface cable provide convenient charging and data management options.

Connectivity and Calibration

Optional BLE wireless connectivity and the MuniDock for convenient bump and calibration underscore the MUNI MP420’s adaptability to modern industrial needs. Up to four factory-configured sensors selected from eight sensor options offer customization to meet specific monitoring requirements.

Cost-Efficient Maintenance

Designed with the end-user in mind, the MUNI MP420’s sensors are replaceable but not interchangeable, reducing maintenance costs and ensuring the device remains calibrated and accurate throughout its lifespan.

Choose MUNI MP420 for Reliable Gas Detection

Whether you’re entering confined spaces or monitoring hazardous locations, the MUNI MP420 gas monitor provides the reliability, durability, and ease of use needed to protect workers in industrial settings. Its advanced features and user-friendly design make it the ideal choice for comprehensive gas detection.
