Hioki 9675 Clamp-On Sensor for HiTester, 10A AC Current

Description

Product Overview

The Hioki 9675 clamp‑on sensor is engineered to complement the HiTester series, delivering high‑precision current measurement in a compact, ergonomic package. Designed for 10 A AC range, the sensor operates across a broad frequency spectrum from 40 Hz to 5 kHz, ensuring accurate readings in both low‑frequency power systems and higher‑frequency applications such as variable frequency drives. Its output of 0.1 V AC per amp provides a clear, linear signal that integrates seamlessly with the HiTester’s display and data logging capabilities.

Constructed from a durable, heat‑resistant alloy, the sensor housing protects the internal coil from mechanical shock and environmental contaminants. The clamp mechanism features a spring‑loaded jaw that securely grips conductors without the need for direct electrical contact, enhancing safety and simplifying setup. With dimensions of 6.3 × 3.6 × 1.8 inches and a weight of just 8 ounces, the device is lightweight enough for handheld use yet robust enough for continuous industrial deployment.

Usage

Designed for a wide range of professional environments, the Hioki 9675 sensor excels in electrical maintenance, troubleshooting, and quality assurance tasks. Electricians can quickly assess line currents in residential and commercial wiring, while maintenance technicians in manufacturing plants use the sensor to monitor motor loads and detect abnormal current patterns that may indicate impending equipment failure.

Because the sensor does not require direct contact with live conductors, it is ideal for use in confined spaces such as conduit trays, switchgear cabinets, and panel boards. Its fast response time enables real‑time monitoring during startup sequences, load changes, and fault conditions, providing critical data for engineers who need to validate system performance against design specifications.

Why Choose Us

Hioki has a long‑standing reputation for precision measurement instruments, and the 9675 clamp‑on sensor upholds that legacy with rigorous quality control and calibrated performance. Each unit undergoes factory calibration against traceable standards, guaranteeing that the 0.1 V AC/A output remains consistent across the entire measurement range. The sensor’s rugged construction is backed by a comprehensive warranty and responsive technical support, ensuring that customers receive prompt assistance and replacement parts when needed.

In addition to its technical merits, the sensor’s user‑friendly design reduces training time and minimizes the risk of measurement errors. The clear markings on the clamp jaw indicate the correct orientation for current flow, and the sensor’s low profile allows it to be stored easily alongside other test equipment. When paired with the HiTester, the 9675 sensor creates a complete solution for accurate, on‑site current analysis.

FAQ

What is the maximum current the sensor can measure?

The Hioki 9675 sensor is rated for a maximum AC current of 10 A, which covers most low‑voltage distribution and control circuit applications.

Can the sensor be used on DC circuits?

While the sensor is optimized for AC measurements, it can detect DC current, but the accuracy may be reduced due to its design focus on AC waveform characteristics.

How does the sensor connect to the HiTester?

The sensor provides a 0.1 V AC per amp output that plugs directly into the HiTester’s dedicated input jack, allowing the instrument to display current values automatically without additional calibration.

Is the sensor suitable for use in hazardous locations?

The sensor’s non‑contact clamp design reduces the risk of spark generation, making it appropriate for many hazardous environments, though users should verify compliance with local safety standards.

What maintenance is required to keep the sensor accurate?

Periodic visual inspection for physical damage and cleaning of the clamp jaws with a soft, dry cloth are recommended. Calibration checks should be performed annually or after any impact event to ensure continued accuracy.
