Accutron MineCO™ Dual Range

Ensure a safe air quality environment for mine re-entry after central blast

The Acc-MineCO is a dual range gas sensor and provides operators with real-time CO gas measurements. This transmitter equipped with dual sensors provides readings of CO from (0-500 ppm) & (0-12.5% Vol).

The Acc-MineCO is specifically designed for underground mining applications, and was developed in compliance with “Ventilation-On-Demand” control strategies.
