The G999C is a versatile multi-gas detector designed for personal protection and confined space cleaning. It combines the features of a modern multi-gas detector with an integrated pump for efficient cleaning of confined spaces, shafts and vessels.

The G999C is equipped with a variety of sensors to detect different types of gases. These include a catalytic combustion sensor for combustible gases, an infrared sensor for CO2, and three electrochemical sensors for toxic gases as well as oxygen.

This sensor configuration allows the device to detect up to seven combustible and toxic gases, thus 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 hazards and for sanitizing confined spaces before entry.

The integrated pump enables efficient air sampling and clearance measurement. 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 body, made of rubberized polycarbonate, provides excellent shock and vibration resistance.

The device features a strong alligator clip for secure attachment and high wearing comfort. Three buttons and a color-backlit screen make operation easy, and the screen can be rotated 180 degrees for increased usability. Additionally, the device features an explosion-proof flashlight to overcome poor lighting conditions.

The G999C features multiple alarm options to alert the wearer when threshold values are exceeded. It uses 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 a distance of up to 100 meters. This enables effective clearance measurement 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 measurement for confined spaces, and efficient gas detection capabilities.

Its rugged 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.
