16 June 2017: Hioki Launches Non-Contact AC Voltage Probe SP3000

Hioki is pleased to announce the launch of the Non-Contact AC Voltage Probe SP3000.

The product’s launch caps the company’s development and commercialization of the world’s first no-metal-contact voltage measurement technology. The small voltage probe takes advantage of this technology to make it easy to observe AC voltage signals in thin cables such as wire harnesses from outside the cable insulation.

Development Background
One sector in which Hioki anticipates the SP3000 will be used is the automotive market, whose products are incorporating an increasingly large and varied number of electronic devices. Vehicles use networks of cables known as wire harnesses to communicate a range of information that is used to control onboard electronic devices.

These wire harnesses are designed to be waterproof, hence there is no exposed metal parts. Consequently, observing the voltage signals they carry has been a labor-intensive task for technicians, who must disconnect the connectors and remove the cable insulation in order to do so.

Hioki has developed and commercialized the world’s first no-metal-contact voltage measurement technology. The newly launched SP3000 takes advantage of this technology to make it easy to observe voltage signals in thin cables such as wire harnesses from outside the cable insulation.

Key Applications
• Observe AC signals from outside the cable cover using recorders and oscilloscopes
• Automotive R&D
• Control system repair and maintenance
