The Toxi Vision Single Gas Detector

NOTE: The Mighty-Tox Was Discontinued Effective July 2008

Replaced by:

ToxiPro Single Gas Detector

The Mighty-Tox is an inexpensive, rugged, single-sensor, disposable gas detector that is available for the detection of either hydrogen sulfide (H2S) or carbon monoxide (CO). Once the Mighty-Tox is activated, it monitors continuously for a full 90-days. A built-in test button lets you verify the unit is operating properly. As the instrument reaches the end of its operational life, a low-battery alarm begins to sound and then continues to sound once per minute for the last seven days of operation. After the Mighty-Tox has reached its end of service life simply throw it away. 

The Mighty-Tox is housed in a rugged, compact, RFI-resistant, metal-plated case that is designed to standup to the most demanding environments. The dimensions are only 1-1/2 X 1-1/8 X 7/8 inches and it weighs less than 1 ounce (25g). The Mighty-Tox features a loud, two-tone audible alarm and bright red LED alarm light. Each Mighty-Tox has two alarm levels, one for warning-level alarms and one for danger-level alarms. Alarm levels vary by instrument type. The loud two tone alarm will warble slowly at the warning-level alarm state and more rapidly at the danger-level alarm state. A strong steel clip allows the detector to be worn on a belt, or clipped to a collar, pocket, or strap. 

The Mighty-Tox is perfect for shut-downs, planned maintenance, and many other short term monitoring applications. It's just the insurance you need that conditions are safe from H2S or CO contamination. 

Each unit is supplied with a "Bump test adapter", which makes it easy to apply test gas to verify proper performance. Test gases are sold separately.
