Marsram Adjustable Digital Torque Wrench, 5-99.6ft.lbs/6.8-135N.m, 5-35mm Jaw, Open End Interchangeable Electronic Torque Wrench With Buzzer And LED, For HVAC Car Moto Repair Tool, Calibrated

Picked this up as I wanted to make sure I had proper torque on a muzzle device. The battery compartment is a little quirky to work with even with the arrows lined up. Otherwise, it functions great. The case holds the adjustable wrench head and looks like it will hold a socket head too. Will need to look at picking one of those up to have on hand. Controls are easy to work with to change through units of measure as well as to dial in the "torgue weight".

Nice

I ordered this wrench to satisfy the requirements of a HVAC project I am currently working on, and was excited to try it out as soon as it came in. To my angst, the operation of installing the 2 AA batteries which should have taken 2-3 minutes took me almost a half hour of figiting with the battery cover and re-reading the poorly illustrated instructions. Once running, I found the torque wrench worked well with a good contrast display, simple menus and stable operation. I was not able to check its accuracy, but I will at least see how it agrees with my older wrench when I get a chance.

Worked as needed. Seems accurate compared to another calibrated wrench I compared it to on a more accessible bolt.

There are digital torque wrench, adjustable head, verification certificates, instructions and tools for installing batteries in the box. Tested this against a known accurate torque wrench and got a nice clear beep when reaching the desired torque. There are 2 models and 4 units to choose from.

Used this against a known accurate torque value and got the clear alarm beep when reaching the value. And the lights changed from green to red when reaching the desired torque. Which is descried in the manual. It was easy to adjust and should work well for the tasks
