In 1985 AC discontinued production of the popular “RT” series of mechanical tachometers. Mitchell immediately entered the market to fill the void. These tachs feature exceptional accuracy and reliability. Mitchell tachs come with a factory-direct 2 year warranty. The range on all models is 500 to 3500 RPM. Accuracy is +/- 25 RPM from 1000 to 3000 RPM. Determine the correct part number from the chart below. All Mitchell tachs are FAA approved to TSO-C49b for certified aircraft. 2-1/4″ tachs are direct replacements for the 3-1/8″ tachs to save panel space. 10-02354 for custom range marks (specify ranges, 4-6 week lead time). Direction of rotation is defined as when viewing the front of the tachometer. |
