I have found that Torque wrenches that are maxed at 150 tend to be more accurate than those that go to 250 in the range I use them.
I'm just curious how you know this. If they are in proper calibration, it would not matter the max limit of the tool, it would be accurate to within whatever percentage of accuracy the calibration room checks it to, at all settings from 20% to 100% of scale.
Response to BWright post with links to Tooltopia PI split beam torque wrenches.
I have the Snap-On versions but mine have rev ratchet heads, I don't like the non rev torque wrencdes
Its the inherent nature of a split beam that it cannot read but one direction. All the ones on the Snap On web site that I could find note that they are either *Non-Reversible* or "torques in a clockwise direction only" Both the PI and Snap On split beams (either made by PI or CDI) would be seriously damaged by pulling a load on them CCW, hence the non reversing ratchet. I'm curious, do you have need to torque counter-clockwise?
TQFR100B, TQFR250E, TQR100B, TQR250E, TQR400E "Designed for measuring torque in a clockwise direction only. Wrench is not reversible."
TQFR50B "Designed for measuring torque in a clockwise direction only. Guaranteed Accuracy: Within ±4% of any clockwise setting from 20% of full scale to full scale"
