Back before the country was "Walmarted" (AKA you only get the quality you pay for) there was a big push for ISO 9000 that required documented processes for everything and the calibration of test equipment was a big part of that for the field. Just about the time all of that infrastructure was in place, the bean counters figured out the number of customers who would actually pay for that quality were far out numbered by those who wanted something just barley good enough to get the job done. I really do not trust that a tool from an offshore discount tool company even reaches that standard. I have one of those Harbor Fright laser pointed IR guns and all I can say is the laser is good for teasing the dog. The gun is horribly inaccurate. There is no way I would trust a torque wrench from those people.
