Module overview

  GM50H MKII is a lightweight, low-cost module used to measure and display engine speed, water temperature, oil temperature, oil pressure, battery voltage and accumulated engine running time. Parameters can be adjusted and set through buttons to meet the needs of different applications. In addition, European-style terminal wiring is used to facilitate the installation and removal of modules.

GM50H MKII series meters are available in two models:

GM50H MKII: Collect engine parameters through resistive sensors, have alarm protection function, and modify parameters through buttons;

GM50HR MKII: On the basis of GM50H, an RS485 interface is added, which can monitor engine parameters and set operating parameters through PC software. Engine parameters and set operating parameters can be monitored through PC software;
