The 122 is certified safe for use in explosive environments by the Canadian Standards Association (CSA - Class 1, groups C & D).

A steady tone and light indicate product and intermittent signals indicate water. The Solinst Interface Meter is rugged, field durable and is easy-to-use. A carrying bag and tape guide are included.
