934 CGM 900 II Series Standard Configuration Plus hydrogen Sulfide (H2S) and Carbon Monoxide (CO) Multi-Gas Detector by GfG
The New Standard in Safety
The CGM combines smart sensor technology with advanced electronics for a truly superior confined space instrument. The groundbreaking ToxAlert sensor, without false alarms, ensures superior protection from hundreds of unknown toxic gases. The AutoCal® feature simplifies and reduces the time required for calibration. With these key features and a power take off (PTO) port for datalogging, an optional mini-pump, remote alarms and other useful accessories, the CGM provides you with the protection and convenience you need.
ToxAlert
Electrochemical sensors are standard in virtually all portable confined space monitors because they can identify specific known gases. However, in many environments such as sewers or storage vessels, unknown gases may be present. For protection in these cases, a broad range sensor is essential. The ToxAlert sensor literally protects you from hundreds of toxic gases with no false alarms. Today’s CGM remains the only instrument to successfully combine the unique characteristics and benefits of both electrochemical and broadrange MOS sensors.
A misconception
It is true that the combustible sensor in conventional gas monitors will also detect most of the gases or vapors listed below. But the concentration levels at which these gases are combustible is usually far in excess to the level at which they pose a threat to health. Some extremely dangerous gases, such as trichloroethylene, are not combustible and would therefore never be detected.
