Precision Power Analysers

Yokogawa's WT series sets the benchmark for power and efficiency measurement. The flagship WT5000 offers up to seven reconfigurable input elements and ±0.03% basic accuracy for power-conversion, motor, inverter and efficiency testing. The WT1800R adds rack-ready, high-channel-count harmonics and efficiency analysis, while the WT500 and WT300E cover mid-range and economy applications such as standby-power and production-line testing. The PX8000 combines precision power measurement with oscilloscope-style transient waveform capture.

Oscilloscopes & ScopeCorders

The DLM3000HD and DLM5000HD high-definition oscilloscopes deliver 12-bit resolution for power-electronics, automotive and embedded development. Yokogawa's ScopeCorder range — the isolated DL950 and portable DL350 — uniquely combines high-speed transient capture with long-duration, multi-channel data acquisition.

Source Measure Units

The GS610 and multi-channel GS820 source measure units combine precision sourcing and measurement in a single instrument for component, semiconductor and materials characterisation.

Precision Calibrators & Standards

Yokogawa's reference-grade sources support metrology and calibration laboratories: the LS3300 AC power calibrator, the 2558A AC voltage/current standard, and the 2560A wide-output precision DC calibrator.

Digital Multimeters

The DM7560 6.5-digit digital multimeter delivers high-accuracy DC and AC voltage, current and resistance measurement for bench and system use.

Calibration & UK Support

Caltest supplies and supports the full Yokogawa Test&Measurement range across the UK. Many electrical parameters — DC and AC voltage and current, power, and harmonics — can be calibrated in our UKAS-accredited laboratory (No. 4432, ISO/IEC 17025:2017). Accredited scope depends on the parameter and range, so please contact us to confirm coverage for your instrument.
