Verifying rotational torque applied by heavy power tools, the RTM 2208 and 2209 non-rotating, square drive reaction torque transducers permit accurate confirmation of static and dynamic torque. They can be used while the device under test is rotating such as calibrating torque wrenches used in make-up and breakout of drill strings in oilfield applications. The components handle capacities from 300,000 to 3,000,000 lbf-in. and offer a compact mechanical package. All models are calibrated CW and CCW to rated load in the company’s NVLAP accredited laboratory. S. HIMMELSTEIN & CO., Hoffman Estates, IL. (800) 632-7873.
