HOBO Self-Describing Current Transformer Sensor
HOBO Self-Describing Current Transformer Sensor
Overview
For use with HOBO MX1104 and MX1105 multi-channel data loggers, this split-core AC current transformer offers integrated strain relief, so the probe is secured to the logger. And it features Self-Describing technology to automatically communicate configuration information to the logger, without any programming or extensive user setup.
