The Wärtsilä EA 96x96.2 s S21 DW is a precision analog RPM indicator with an integrated hour meter, manufactured by Dr. E. Horn GmbH in Germany for marine engine applications. It displays engine RPM (scaled ×100) and turbocharger RPM (scaled ×1000) on a 96x96 mm analog dial, alongside a digital hour counter to track operating hours. Designed for robust performance in harsh marine environments, it provides clear, reliable visual monitoring of engine and turbocharger speeds, supporting preventive maintenance and operational safety for Wärtsilä marine diesel engines.
