My torque wrench is my hand and the way I hold the tool in question. And lots of experience with stripped bolts I guess.
Realms of possibilities. Experience is the factor, learning torque’s by hand are incredibly precise, but leaning that feel using a torque wrench is cheaper, yet decreasing the learning curve on how to fix mistakes. I remember as a kid the lesson of a spark plug thread tapped direct to an ally head.
Precision engineering may ask 1Nm difference, difficult to feel by hand.
To OP, Halfords stock a professional range made by Norbar, the 3/8 covers 8-60Nm.
