An apparatus for measuring forces acting on a tubing string within a wellbore, comprising a body including a central passage and an internal void radially offset from the central passage. End portions extending from the body each include an internal passage and an interface configured to detachably couple to the tubing string for conveyance within the wellbore. A clamp is detachably coupled to one end portion, and first sensors coupled to the clamp are configured to detect strain induced by forces acting on the tubing string. At least one second sensor coupled to the body is configured to detect pressure and temperature within the wellbore. A memory device coupled to the body within the internal void is configured to log measurements detected by the first and second sensors. An electrical power supply coupled to the body within the internal void is configured to provide electrical power to the memory device.
