AC/DC Auto Zero Current Sensor (2000A DC-5kHz) CT7742
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki's expertise in current sensing technology. The CT7742 is a 2000 A AC,DC Current Sensor that pairs with the detachable Display Unit CM7290 for convenient field testing, while delivering an extended temperature range and auto-zero adjustment to minimize drift due to wide temperature changes that occur during long-term testing. Further extend the functionality of this system by connecting the Display Unit with a Hioki memory recorder or logger.
CAT IV 600 V
Key Features
- Accurately measure and record even when the temperature changes
- Ideal for site inspections by using detachable Display Unit - Four output formats to output data to loggers or other devices (via Display Unit): WAVE, RMS, PEAK, Hz
Product Warranty Period: 3 years
Included Accessories:
None
