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. Today's CGM remains the only instrument to successfully combine the unique characteristics and benefits of both electrochemical and broadrange MOS sensors. 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 ensures you superior protection from hundreds of unknown toxic gases, and the AutoCal feature simplifies and reduces the time required for calibration. With these key features and a power take off (PTO) port for data logging, an optional mini-pump, remote alarms and other useful accessories, the CGM provides you the protection and convenience you need.
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. The CGM's broad range ToxAlert protects you from hundreds!
Conventional toxic gas detectors can protect you from only two or three gases.

What does OSHA think about broadrange sensors?
"Where the employer has already identified (atmospheric) hazards, substance-specific sensors are preferable, because they accurately indicate the concentrations of identified air contaminants. By contrast, where the employer has not been able to identify the specific atmospheric hazards present or potentially present in a sewer, broadrange sensors are preferable because they indicate that the hazardous threshold of a class (or classes) of contaminants (i.e. hydrocarbons) in the sewer have been exceeded." -1993 Confined Space Standard: 29CFR1910.146 Appendix E
