Changsha, China · Probemart

Company Overview

Probemart (探头之家) is the own brand of Jectronic Instruments, a Chinese specialist in power-electronics test probes and sensors based in Changsha, Hunan. Probemart combines distribution of leading international probe brands with application expertise, product selection guidance and locally supported measurement solutions for SiC/GaN double-pulse testing, inverter development and battery test.

History

Established as an instrumentation distributor serving Chinese power-electronics manufacturers, Jectronic built its business on technical support rather than catalogue sales. As domestic demand for wide-bandgap device characterisation grew, the company assembled a portfolio spanning voltage probes, current sensors, shunts, temperature sensing and complete double-pulse test benches, and developed the Probemart platform to publish evaluation data and selection guidance.

Strengths

Three strengths stand out: brand coverage (IWATSU, PMK, PEM, T&M, Danisense, CIC, GMW, LEM and more through one channel), measurement know-how (engineers who run their own double-pulse benches and publish the results), and local service (Chinese-language support, fast delivery, calibration coordination and loan instruments for evaluation).

Product Portfolio

• High-voltage differential and isolated voltage probes
• Rogowski, hall and fluxgate current sensors plus coaxial shunts
• Fibre-optic and isolated temperature sensors
• Probe calibration sources and double-pulse test fixtures/systems
• Selection tools, calculators and published evaluation reports

Probemart's role is to make the right measurement possible: matching probe bandwidth, voltage rating and current range to the device under test, then supporting the bench after delivery.
