Facom 1/2" Drive Electronic Torque Wrench (7-135nm , approx 5-100 ft lbs)(E.306A.135S) - with detachable ratchet head. The wrench body is the heart of a highly flexible system (9x12mm accessories can be purchased separately) which enables the accurate torquing of fasteners, including those in tight spots that cannot be accessed with a socket. Accuracy to +/-2% . Comes in a foam lined storage case.
I feel the 306 series (mechanical or electronic versions) are the best all around torque wrenches that Facom makes today. Great accuracy and flexibility for use in the laboratory or workshop. Plus you've got the option of using the open end or ring end attachments when a ratchet/socket approach is not an option. Features of the "E-Series" torque wrenches are ....
- High Performance even under intensive use - accurate to ± 2% ±1 digit.
- Can be preset to 9 torque values.
- USB connection allows storage of 250 values.
- LEDs remain visible, even where access is difficult.
- Ultra simple to use: self test and reset when switched on.
- Visual and audible indications (LEDs and beeper).
Note - I've received 2 of these in the last 3 months and both have calibration certificates showing far better than +/-2% accuracy. In fact, at each of the 3 calibration points, 27nm/81nm/135nm (20%, 60% and 100% of the range), the worst deviation for spec was 0.4%.
