Handheld Dynamic Strainmeter DH-14A

The DH-14A is a handheld and battery-operated dynamic strainmeter having 4 measurement channels. Dynamic strain is easily measured while monitoring numerical values and wave forms. Trigger measurement mode and free-run measurement mode are available. The DH-14A is well suited not only for measurement in fieldwork or on moving object, but also for checking sensors and input noise as a checker. Using 4 AA alkaline batteries commercially available, the meter allows measurement for 4 consecutive hours (or for 6 hours in power saving mode).
