The G999C is a versatile multi-gas detector designed for personal protection and clearing confined spaces. It combines the features of a modern multi-gas detector with an integrated pump for efficient clearance of confined spaces, shafts, and vessels.
The G999C is equipped with various sensors to detect different types of gases. It includes a catalytic combustion sensor for flammable gases, an infrared sensor for CO2, and three electrochemical sensors for toxic gases as well as oxygen. This sensor configuration enables the device to detect up to seven combustible and toxic gases, providing comprehensive gas monitoring capabilities.
The multi-gas detector is suitable for a wide range of applications due to its versatility. It is particularly useful for personal protection against gas dangers and for clearing confined spaces before entry. The integrated pump allows for efficient air sampling and clearance measurements.
In terms of safety and operation, the G999C is certified for use in Ex zone 1 environments and offers protection against water and dust ingress (IP67 rating). The housing, made of rubberized polycarbonate, provides excellent shock and vibration resistance. The device features a robust crocodile clip for secure attachment and high wearing comfort. The three buttons and color-backlit display make it easy to operate, and the screen can be rotated by 180 degrees for improved usability. Additionally, the device includes an explosion-proof flashlight to address poor lighting conditions.
The G999C incorporates multiple alarm options to alert the wearer when threshold values are exceeded. It utilizes light signals, vibration, and a loud buzzer (103 db(A)) to ensure immediate awareness of hazardous conditions. The integrated NiMH battery offers a long operating time of up to 130 hours, depending on the operating mode and sensor configuration.
The pump performance of the G999C is efficient, capable of sampling approximately 0.6 liters per minute from distances of up to 100 meters. This allows for effective clearance measurements in confined spaces and other challenging environments.
Overall, the Polytector III G999C is a reliable and versatile multi-gas detector that provides personal protection, clearance measurements for confined spaces, and efficient gas detection capabilities. Its robust design, long battery life, and integrated pump make it suitable for demanding applications, while its user-friendly features and multiple alarm options ensure safety and ease of use.
