The Uni-T UT705 is a high-performance portable current loop calibrator engineered for precision measurement and sourcing. Whether you are working in a laboratory or out on a demanding job site, this tool provides the accuracy and reliability required for professional process control and instrumentation maintenance.

Designed with a compact and ergonomic form factor, the UT705 fits comfortably in your hand, making it ideal for long days of field service. It allows technicians to fine-tune loops with exceptional speed and accuracy, ensuring that critical industrial systems remain operational and within specification.

Why It Matters

In HVAC and industrial automation, even a minor discrepancy in loop current can lead to system-wide calibration errors. The UT705 offers a 0.02% accuracy rating, providing the confidence that your transmitters and controllers are being calibrated to laboratory standards, which helps prevent equipment damage and reduces costly system downtime.

What's Included

• ✓ UT705 Portable Current Loop Calibrator
• ✓ Professional-grade test leads
• ✓ 9V battery (pre-installed)
• ✓ Comprehensive user manual

Features & Benefits

• Dual Functionality: Measure DC voltage, current, and loop current while simultaneously sourcing or simulating DC current up to 24mA.
• Integrated Loop Power: Built-in 24V loop power supply allows you to power and test transmitters directly without needing an external power source.
• Advanced Testing Modes: Features slow ramp, fast ramp, and a 25% step-ramp function for efficient and repeatable linearity testing.
• High Precision: Achieve professional results with 0.02% accuracy for both measurement and sourcing functions.
• Data Memory: Save and quickly recall frequently used settings to streamline repetitive calibration tasks.
• High-Visibility Display: The large 63mm x 40mm backlit LCD ensures readings are clear in dark mechanical rooms or outdoor environments.

Applications

• ✓ Calibrating and troubleshooting 4-20mA process control loops.
• ✓ Powering and testing 2-wire industrial transmitters.
• ✓ Verifying PLC and control system input/output signals.
• ✓ Performance testing of flow, pressure, and temperature sensors.

Tradie Pro Tip

When performing a quick linearity check on a 4-20mA loop, use the 25% step-ramp function. It automatically cycles through 4, 8, 12, 16, and 20mA, allowing you to verify the controller response at every major interval without having to manually adjust the output for each step.
