President and Chief Operating Officer at Teledyne Technologies
Thanks, Edwin. Thanks Edwin. The Instrumentation segment consists of our Marine, Test and Measurement and Environmental businesses, which contribute a little over 23% of sales. For the total segment, overall, fourth quarter sales increased 2.8% versus last year.
Sales of Marine Instruments increased 14.7% in the quarter, primarily due to strong offshore energy sales, but also continued growth in Global Defense and Ocean Science markets.
Sales of Electronic Test and Measurement systems, which include oscilloscopes, digitizers, and protocol analyzers, were flat year-over-year. We continued to see some softness in sales of analyzers for electronic storage and data centers applications, but this was largely offset by continued strong sales of oscilloscopes and a small amount of incremental sales from the Xena acquisition.
Sales of Environmental Instruments decreased 7.3%, with greater sales of air quality and gas-inflamed safety analyzers more than offset by lower sales of drug discovery and laboratory instruments. Overall, Instrumentation segment operating profit increased over 14% in the fourth quarter, with GAAP operating margin increasing 284 basis points to 27.1% and 278 basis points on a non-GAAP basis to 28.1%, both all-time records for the segment.
In the Aerospace and Defense Electronics segment, which represents 13% of Teledyne sales, fourth quarter sales increased 3.4%, primarily driven by growth of commercial aerospace products. GAAP and non-GAAP segment operating profit decreased approximately 5% year-over-year, primarily due to a tough comparison with last year's all time record segment margin. For the Engineered Systems segment, which contributes 8% to overall sales, fourth quarter revenue decreased 3.8%, but operating profit increased with margin up 325 basis points.
I will now pass the call back to Robert.
