Add to Wishlist
Part# 10-04478
MFR Model# TM200S


The TM200 is a precision tachometer that provides RPM data accurate to +/- 1RPM. It meets all the requirements of TSOC49b and provides the following functionality:
  • RPM indication in both analog and digital format, including support for engines that require a limited RPM range
  • Engine time
  • Trend graph function representing RPM vs. Time
This instrument requires a 0-5V DC pulse width modulated signal to provide RPM output. The input signal can be derived from an electronic ignition system or Hall Effect magneto sensor. The instrument will work on all 4, 6 and 8 cylinder aircraft engines.

    I ordered this Tachometer for my Cessna 150. This is a great Tachometer! I love the way it looks and it was super easy to install. Works great and gives an accurate reading. Great upgrade from my mechanical tachometer. I love how you can enter your current tach time so you don’t have to start at 0 and covert everything. I would definitely consider this tachometer for your instrument panel, it worked out great for me!
