The DA100 is a "SMART" gas detector designed to detect and monitor flammable gases in the air in the range of 0-100% LEL using Catalyst Cell technology.

The DA100 is an intelligent electronic device that applies Rezontech's unique algorithm and has a user interface and comprehensive fault diagnosis capabilities.

The transmeter design also features Rezontech's advanced technology suitable for Catalyst Cells. The gas-sensitive sensor assembly is stainless steel and the transmeter housing is designed to protect against corrosion and other effects by coating aluminum with epoxy and with an internal pressure-resistant structure.
