Hioki-CT7731 AC/DC AUTO-ZERO CURRENT SENSOR
Accurate, Long-term Recording and Easy Output Settings
Key Features and Functions
- 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
Documents and Software:
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CT7731 is a 100 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 or CM7291 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.
Accuracy guaranteed: 3 years, Accuracy guarantee period after adjustment made by Hioki: 3 years
