What's the difference between these two torque wrenches?

[Wamsutta]

M1R200H = 40 - 200 lb. in.

M1R200HX = 30 - 200 lb. in.

Is that the only difference?

I think you'll need to call them up to confirm. The HX model isn't even listed on their M series brochure.

ANSI specs are different

Difference is in calibration, and graduation steps. HX is 3% at 15% of scale, while the H is 3% at 20%. H is a 1 lb/in graduation, while the HX is .5 lb/in. Had to go to product resources and then Customer print to find the info.

ANSI B107.14M was superseded by B107.14, which has been consolidated into ASME B107.300-2010

@cvairwerks
The references are posted below for others to quickly see.
I do believe they incorrectly stated the X model as having .5 increments.
It appears to be the same 1 unit step on both models. (Both product webpages correlate.)

The accuracy remains the same on both models at 3% of stated full range capacities.
The 15%/20% of full scale is just the minimum stated capacities of 30/40 LB.IN.

I see no difference, other than the extended minimum range on the X, and the resulting handle length variation.

Knurled: Look carefully at the drawings...the H drawing show shows a 1 lb/ft increment count, while the HX drawing shows a .5 lb/ft count.

Yes, the X blueprint appears incorrect.
I have the MIR200H. Comparing it to an actual product pic of the X, its the same.

What’s the precision rating on them?
