Superior Accuracy

Outperform other competitors on the market, CT10x boasts an impressive high sampling frequency of up to 3.3kHz, guaranteeing unparalleled accuracy and detail.

Efficient Energy Tracking

At One-Second Interval

Calculate accumulated ampere hour in real-time at a one-second interval. This enables precise current consumption monitoring and analysis, achieving goals such as energy conservation and reduced operational costs.

Non-Invasive Installation

Split core product design for non-invasive and quick installation,
eliminating the risk of circuit damage or power interruptions.

External Wire
Temperature Sensor

An external wire temperature sensor is available, triggering alerts when
the wire temperature reaches a set threshold.

Irregular Current Status Alert

Current Threshold Alert

Set minimum and maximum current thresholds, and receive instant alarms upon threshold triggers for swift action.

threshold alert

Over-Current Alert

Receive instant alerts when actual current exceeds the rated limit, accompanied by a smart LED indicator flashing every 2 seconds for swift visual confirmation of the alarm status.

Compact Industrial Design

Select from Multiple Antenna Types

CT10x is equipped with a high-gain antenna, ensuring stable signal transmission. And the magnetic antenna is also offered as an optional choice to meed your specific needs

Cable-free

Say goodbye to the hassle of wires. This simplifies the installation process, reduces labor costs, and allows for more flexible placement.
