Originally designed to measure the tension on telephone wires, the AP Dynamometer has proven to have limitless versatility as a tension and weight measuring instrument. It is used for such diverse jobs as suspended weighing, mounting cables for bridges, adjusting tension on guy wires, field testing chain and rope as well as wire. Basically anything requiring precision force or tension measurement.
Standard Model AP Dynamometer includes: Dynamometer, shackles and pins, maximum pointer, zero adjust for tare, molded plastic carrying case on 5" models and calibration certificate.
Zero dial position is aligned with shackles (9 o'clock position). Alternate zero dial position is available if specified at the time of order.
