I got an electronic unit from HFreight that is like an extension, I/4, 3/8,1/2 inch adaptors included for about $30. It makes your ratchet a torque wrench. Lasted three years so far.

I?d suggest two with a decent overlap range. It?s an easy task to check calibration against the two in the overlap range.
And if they're different? Which one is wrong?
I take all of mine to a local shop every few years that can certify them back to the NIST standards. Maybe it's overkill for our planes, but IMO, there's a right way to do things...
I would be interested in knowing how accurate that thing is. have you compared it or calibrated it to a known good torque wrench?
I have a large beam style torque wrench. They don't go out of calibration, unless you drop them, which is no different than any other toque wrench.
The one I have is a Vintage Craftsman from about 1983.
They even survive a drop. Just read the scale before use and make any adjustments needed to "O". The pointer does not move during use. And the main beam can only be changed with a great amount of heat.
The main advantage is the head is a lot smaller than a click wrench that it can fit where the click won't. And they never need calibration.
That's the one to own! Electronic wrenches are accurate and repeatable. Your beam type wrenches accuracy is 10-20%, HF is 1-2%. So which one would you use?
Worked fine at first, but now my HF eats batteries like there's no tomorrow.
I guess for occasional use one could up an external battery.
