PC control Dynamic Strainmeter DC-004P
The DC-004P is a PC control type dynamic strainmeter. It stores measured data in a PC which is connected via USB interface, without having a recording medium in the strainmeter. Since a continuous recording is possible, this strainmeter is most suited to measurement such as material testing.
- Features
- Manual trigger, data trigger and Interval trigger can be executed at the same time
- 50 kHz sampling (at the fastest in 1-channel mode)
- Simultaneous sampling of 12.5 kHz for 4 channels (4-channel type)
- Capable of measuring a large strain of up to 80000×10-6 strain (with 0.5 V excitation)
- Direct recording on a PC
- Supporting long term measurement
- 4-channel type and 2-channel type are supportable
- Measured data conforms to DADiSP format
- TEDS compatible
- Control software (DC-7004P) supplied as a standard accessory

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).
- Features
- Simultaneous sampling of 4 channels
- Measured data indicated by waveform
- ECO mode (power saving mode) equipped
- Powered by 4 AA alkaline batteries
- Measured data conforms to DADiSP format
- TEDS compatible
