Rugged, flexible, easy to maintain

Teledyne's Model 1220 microprocessor-controlled gas detection system is specifically designed to monitor industrial locations such as refineries and chemical plants, and warn of the presence of potentially explosive gases and vapors. In addition, the 1220 can activate ventilation or sprinkler systems or shut down process equipment until the danger is eliminated. Developed in collaboration with plant personnel who utilize gas detection equipment, the 1220 is a blend of flexibility and simplicity with state-of-the-art electronics. Advantages • Dependable microprocessor based electronics • 1...
