Macurco PM100-CO Portable Carbon Monoxide Gas Monitor

The Macurco PM100-CO AimSafety is a portable, disposable single-gas carbon monoxide detector designed for continuous personal exposure monitoring in industrial and hazardous environments. Featuring a 0-500 ppm CO detection range, 1 ppm resolution, and factory alarm thresholds of 35 ppm and 100 ppm, it provides audible, visual, and vibrating warnings when carbon monoxide concentrations reach hazardous levels. The monitor includes an LCD display, IP67-rated housing, 30-event memory, and a non-replaceable lithium battery supporting up to 2 years of continuous operation under specified conditions.

Macurco PM100-CO AimSafety Portable Carbon Monoxide Gas Detector

The Macurco PM100-CO AimSafety Single-Gas Monitor is a compact, wearable carbon monoxide detection instrument engineered to monitor occupational exposure to CO gas in industrial workplaces, confined spaces, and potentially hazardous environments. Part of the Macurco AimSafety PM100 Series, the detector continuously measures ambient carbon monoxide concentrations and displays real-time readings on an integrated LCD screen. Its electrochemical CO sensor provides a measurement range of 0 to 500 parts per million (ppm) with 1 ppm resolution, allowing personnel to identify changes in carbon monoxide levels during routine operations and potentially hazardous activities. The monitor features factory-configured low and high alarm thresholds of 35 ppm and 100 ppm, respectively, with alarm settings configurable through compatible Macurco programming accessories. Designed for personal protection, the PM100-CO is suitable for industrial maintenance technicians, utility workers, construction personnel, oil and gas operators, wastewater treatment employees, and workers exposed to combustion-related carbon monoxide hazards.

The PM100-CO incorporates a three-mode alarm system combining audible, visual, and vibrating notifications to alert personnel when carbon monoxide concentrations exceed configured limits. Its audible alarm produces approximately 90 dB at 4 inches (10 cm), while flashing red LEDs, vibration alerts, and LCD indications provide additional warnings in noisy industrial environments. Distinct low- and high-alarm patterns help workers recognize the severity of detected gas exposure. The instrument features a 3.6 V non-replaceable lithium battery and is designed for a continuous operating period of up to 24 months from activation, based on specified usage conditions, including approximately two minutes of alarm activity per day. Its maintenance-free, disposable design eliminates routine battery and sensor replacement, while the integrated status indicators provide notifications for alarm tests, bump tests, calibration requirements, and remaining sensor life. A 30-day end-of-life warning informs users when the instrument is approaching the end of its operating period.

Constructed with a rugged polycarbonate and rubber housing, the Macurco PM100-CO features an IP67 ingress protection rating, providing dust-tight construction and protection against temporary water immersion under standardized test conditions. The compact detector measures approximately 3.34 inches long, 1.92 inches wide, and 1.56 inches high, including its attachment clip, and weighs approximately 3.3 ounces (93 grams). Its operating temperature range extends from -40 F to 122 F (-40 C to 50 C), with an allowable relative humidity range of 5% to 95% non-condensing. The monitor features single-button operation, a high-visibility housing, and a clothing attachment clip for hands-free personal gas monitoring. Its internal memory records up to 30 alarm and bump-test events, supporting exposure event review and safety program documentation. Compatible accessories include the Macurco PM-Link computer interface, which supports instrument configuration and event access, and the PM100-STN bump-test and calibration station, which assists with functional testing and calibration procedures.

The Macurco PM100-CO is designed for workplace environments where carbon monoxide exposure presents a respiratory and occupational safety hazard, including boiler rooms, mechanical equipment areas, industrial plants, maintenance operations, construction sites, and oil and gas facilities. The detector carries hazardous-location certifications that include UL 913 and CSA C22.2 No. 157 for Class I, Division 1 and 2, Groups A, B, C, and D, along with ATEX II 1G Ex ia IIC T4 Ga and IECEx Ex ia IIC T4 classifications for intrinsically safe operation in applicable hazardous environments. Unlike permanently installed Macurco carbon monoxide detectors designed for building automation, ventilation control, or fixed gas monitoring, the PM100-CO is a self-contained personal safety instrument intended to accompany individual workers. Its disposable two-year operating design, automatic gas measurement, multi-sensory alarms, and event logging support occupational gas safety programs without requiring routine battery replacement. Although the instrument is described as maintenance-free, users must follow the manufacturer's instructions for required bump testing, calibration verification, and pre-use inspection. The PM100-CO includes a two-year manufacturer warranty from activation, subject to applicable warranty conditions and proper operation.
