applied to measuring up to three different objects' electricity.
Non-Invasive Installation
The user-friendly current clamp probe is designed for non-invasive and quick installation, eliminating the risk of circuit damage or power interruptions.
Self-Powered:
No Batteries, No Limits
The CT3xx is designed to derive power directly from the measured circuit, eliminating the constraints of batteries while ensuring seamless operation
Superior Accuracy
Outperform other competitors on the market, CT3xx 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.
Irregular Status Alert
Current Threshold Alert
Set minimum and maximum current thresholds, and receive instant alarms upon threshold triggers for swift action.
Over-Current Alert
Receive instant alerts when the actual current exceeds the rated limit, accompanied by a smart LED indicator flashing every 2 seconds for swift visual confirmation of the alarm status.
Temperature Threshold Alert
An external wire temperature sensor is available, triggering alerts when the wire temperature reaches a set threshold.
Simple Cable-Free
Deployment
