Kyoritsu BBK VP-01U Phase Checker/Voltage Detector
Product Description
Voltage range: AC 100–1000 V
Frequency: 45–65 Hz
Operating temperature / humidity: -10 to 40°C, up to 75% RH (no condensation); +40 to +50°C, up to 45% RH (no condensation)
Storage temperature / humidity: -20 to 60°C, up to 80% RH (no condensation)
Power supply: 2 x AAA dry batteries
Battery life: Approx. 150 hours (with alkaline batteries)
Dimensions / weight: W21 × H153 × D26 mm, approx. 50 g (including batteries)
VP-01U Key Benefits
This compact, lightweight tester works reliably on thin or thick wiring and in narrow spacing, making it suitable for a wide range of job sites. The integrated body and sensor measure only 153 mm in length and weigh about 50 g, allowing easy storage in a pocket or on a belt and excellent portability.
The innovative measuring method does not require clipping onto insulated wires, and can confirm phase sequence in three-phase three-wire and three-phase four-wire systems. The pen-like slim tip simply touches the distribution cable, enabling quick measurements even inside crowded panels. A non-contact voltage detection function is also included, with clear LED indication, color display, and beeping sound for intuitive, easy-to-understand results.
