FOR IMMEDIATE RELEASE
NEW PM500 Portable Monitor
Sioux Falls, SD – January 2025
Macurco Gas Detection, a leading developer of gas detection solutions for fire and security, HVAC, industrial, and personal safety, is proud to announce the launch of its latest product, the AimSafety PM500 Multi-Gas Portable Monitor.
This rugged handheld, combined with a strong internal pump, can simultaneously measure up to six gases to allow for safe entry in confined spaces and hard-to-reach areas. PM500 monitors are equipped with audible, visual, and vibrating alarms to alert users of unsafe gas concentrations. The large backlit LCD provides sampled gas concentrations in real time along with configurable alarm setpoints (low, high, STEL, and TWA). Standard target gases include carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and combustible gases. Additional gas options include ammonia (NH3), sulfur dioxide (SO2), nitrogen dioxide (NO2), volatile organic compounds (VOCs) and others.

We’re excited to introduce our new PM500 Series of Multi-gas monitors with a built-in pump. This essential addition to the AimSafety product line completes our full suite of portable gas monitoring solutions. Engineered for rugged performance, this instrument boasts a large, easy-to-read screen, IP67 protection, and the ability to detect up to six gases. With data and event logging, plus a quick connector for seamless transitions between sampling and calibration modes, it’s designed for the toughest environments. The integrated pump allows users to safely pull air samples from potentially hazardous confined spaces before entry, ensuring real-time readings from a secure location. – Jace Krumwiede, Product Manager Industrial Safety
