Portable Dynamic Strain Tester

This tester fills a gap many labs overlook: bringing lab-grade dynamic measurement to field sites without sacrificing accuracy. Inside, signal conditioning blocks handle quarter-, half-, and full-bridge strain gauge circuits with low drift, so you get clean data even under direct sun or after a long cable run. Multiple analog-to-digital converters run simultaneously across all channels, avoiding phase skew between sensors—something critical when calculating mode shapes on a vibrating structure. Sampling rates can be set high enough for shock events or dialed down for slow monotonic tests, and the local storage holds hours of continuous records without needing a laptop tethered to the box. Because Kingmach makes its living from geotechnical instruments, the housing is sealed against dust and drizzle, and terminals are arranged to prevent accidental yanks from pulling wires loose. The interface, while not flashy, shows live waveforms and peak holds at a glance, which saves time when checking sensor placement before a test. For teams who need remote access, optional 4G or Wi-Fi modules stream data to a cloud dashboard or a technician’s phone, making it easier to monitor a bridge loading test from the pier instead of hanging off scaffolding. Being a mid-range instrument, it doesn’t carry the premium of lab giants, yet the autozero routines and shunt calibration steps deliver repeatability that holds up well in structural health monitoring. Kingmach’s global distributor network means spare cables or calibration certificates don’t get lost in international logistics, and engineers can request firmware tweaks for uncommon gauge factors or excitation voltages without waiting for a next-gen release.
