Professional disposable CO detector with 2-year battery life, hibernation mode, dual alarms, and hazardous area certifications. Zero maintenance required.
The Teledyne GMI Protege ZM is a premium disposable single gas detector specifically designed for Carbon Monoxide (CO) detection with alarm thresholds set at Hi 35ppm and HiHi 200ppm. This zero-maintenance unit operates continuously for approximately 2 years without requiring calibration, charging, or maintenance. The detector features an innovative hibernation mode that can extend battery life for up to one additional year, making it an economical choice for long-term gas monitoring applications. Simply activate the monitor and it will run 24 hours a day for the entire service period, providing reliable and consistent protection against carbon monoxide hazards.
Designed for professional safety applications, the Protege ZM combines advanced technology with user-friendly operation. The unit features dual high-visibility LED alarms that flash when gas is detected, complemented by a 95dB audible alarm and vibrating alert system. The display provides real-time information including time remaining in the monitor's life, gas type, functional test validation status, bump test due indicators, and battery level. With its compact size (3.7" x 2.2" x 1.3") and lightweight construction (2.7 oz), this detector is ideal for workers who need portable, reliable protection without the burden of regular maintenance.
The Protege ZM is fully certified for hazardous area use with ETL/CETL certification to UL 913 7th edition, CSA C22.2 No. 157, ATEX II 1 G Ex ia IIC T4 GA, and IECEx certifications. It features an impact-absorbent rubber casing, IP66/67 rating for dust and water protection, and operates reliably across a temperature range of -30°C to 50°C. The device includes a stainless steel alligator clip for secure attachment and supports data logging of the last 25 events with backup capability via infrared connection to PC. Configuration options are available through the IR Connect Module and dedicated software, allowing for customized settings and inventory management via six-character user IDs.
