The REED SD-6020-NIST is a data-logging push/pull force gauge with a 20 kg (44 lb) capacity and a reversible display that stays readable no matter which direction the load is applied. It records tension and compression readings directly to an SD card at a user-selectable sampling rate, generating an Excel-ready file without needing separate software, and supports both normal and peak-hold measurement modes. It ships with a hard carrying case, connecting hooks and cable, and includes a NIST-traceable calibration certificate for accuracy-critical testing.
