Gas detectors for rough work sites

Altair's Pro toxic gas and oxygen detectors accurately measure the gas concentration or percent oxygen (depending on model), and displays the information on a backlit LCD. The detector, from MSA North America, features dust and water protection, impact resistance, strong RFI performance, and an alarm system. Adjustable alarm set points are offered for “Low” and “High” levels on all units. In addition, the toxic gas versions also have TWA and STEL alarm points. A distinct alarm is indicated by two flashing LEDs, an audible alarm, a fiashing notification on the LCD, and an internal vibrating alarm, helping to ensure that no alarm condition will go unnoticed.

Current sensor options are for CO, H2S or O2. The sensors and battery can easily be replaced and its rubberized armor housing and one-button operation are for durability. The detector is part of the MSA Stellar series, which is a selection of single- and multi-gas instruments.
