CEM DT-9812 Leakage Current Clamp Meter [AC TRMS, mA – 1000A]

Clamp meters (especially high-precision leakage current clamp meters) are highly effective and safe tools for detecting weak leakage currents. They can perform measurements without disconnecting the circuit, making them ideal for online monitoring and troubleshooting of equipment or systems.

Category: Clamp Meters

The DT-9812 clamp meter has a current testing range from milliamperes to 1000A AC current, covering five ranges: 200mA (100μA resolution), 2A (1mA), 20A (10mA), 200A (100mA), and 1000A (100mA), meeting the needs for accurate detection from weak leakage current to large load current.

It is resistant to external magnetic field interference. When subjected to a 100A external magnetic field within a Φ15mm range, the error is controlled within 10mA, ensuring the reliability of data in the strong electromagnetic environment of the substation.

Safety:

IEC61010-1 CAT III 600V / / CAT IV 300 V
UL, CSA, and TÜV listed for maximum safety and global compliance

Applications:

-- Preventive Maintenance: Regularly inspect the insulation condition of critical electrical equipment (such as data center UPS, medical equipment, and production line controllers).
-- Fault Diagnosis: Locate faulty equipment causing frequent tripping of residual current devices (RCDs).
-- Installation Acceptance: After new equipment is installed, verify that its leakage current meets safety standards.
-- Energy Consumption Analysis: Assess the energy loss caused by leakage in the system.

Precise detection of milliampere-level leakage current and operational safety under high-voltage environments

In power maintenance sites, leakage problems are often difficult to locate due to weak signals and complex environments.

- The weak leakage current was drowned out by the noise.
- Low efficiency in dense wire harness detection
- High-voltage environment operation risks

CEM DT-9812 Its ultra-large jaws for multi-wire measurement, milliampere-level leakage current detection accuracy, anti-interference capabilities, and industrial-grade safety protection technology directly address industry pain points
