High-Precision Industrial Multimeter – UNI-T UT197

Laboratory Precision for Extreme Industrial Environments

The UNI-T UT197 is an elite-tier industrial digital multimeter designed to bridge the gap between laboratory-grade accuracy and field-rugged durability. Specifically engineered for the most demanding sectors in South Africa—including petrochemical smelting, power engineering, and heavy manufacturing—the UT197 offers an unprecedented 600,000-count resolution. This allows for microscopic voltage analysis even in the harshest outdoor conditions, where extreme temperatures and mechanical shocks are standard.

Unmatched Precision and Extreme Ruggedness

The UT197 is optimized for high-fidelity data capture in high-risk environments:

• Elite 600,000-Count Resolution: Provides industry-leading DC voltage accuracy of up to 0.015%, essential for calibrating sensitive control systems and monitoring high-stability power rails.

• IP67 & 5-Meter Drop Protection: Built to survive total immersion in water and accidental high-altitude drops onto concrete, ensuring zero downtime in rigorous field applications.

• Extreme Temperature Resilience: Rated for operation from -40°C to +55°C, making it the definitive choice for cold storage facilities, desert-based solar plants, and furnace-adjacent industrial zones.

Advanced Diagnostics and Smart Integration

Equipped with cutting-edge measurement technology which essentially simplifies complex troubleshooting:

• VFD Low-Pass Filter: Effectively filters out high-frequency carrier noise from variable frequency drives, providing stable and accurate voltage/frequency readings on motor controllers.

• Bluetooth & UNI-T SmartTest App: Enables wireless real-time data logging and professional report generation (CSV/PDF) on mobile devices (phones), keeping technicians at a safe distance from live high-energy circuits.

• Peak Capture & LoZ Mode: Features a 250$\mu$s peak capture for transient signal analysis and a Low Impedance (LoZ) mode to eliminate ghost voltages in complex wiring harnesses.

Industrial Safety and Compliance

The UT197 is certified to CAT IV 1000V safety standards and features 12kV pulse impulse protection. With an audible and visible mis-plug alarm and a high-speed 33-segment analog bar graph, it provides a safe, intuitive, and highly responsive user experience for professional engineers.

Professional Application Scenarios

• Petrochemical & Smelting Operations: High-precision monitoring of process control sensors in environments requiring IP67 dust and water protection.

• Power Engineering & Construction: Auditing high-voltage distribution systems and verifying insulation integrity in all-weather conditions.

• VFD & Motor Diagnostics: Troubleshooting industrial drive systems using the specialized anti-interference VFD mode.

• HVAC & Large-Scale Refrigeration: Precision temperature and electrical auditing in extreme cold-storage environments.

• Laboratory & Calibration Services: Utilizing the 600,000-count resolution for the calibration of secondary electrical instruments and sensors.

Maintenance and Best Practices

• Terminal Protection: Use the included dust plugs for the input terminals when the meter is not in use to maintain the IP67 integrity and also prevent terminal oxidation.

• Seal Inspection: Periodically check the battery compartment gasket for any debris or wear to ensure the waterproof seal remains intact.

• Bluetooth Range: For optimal data logging, maintain a clear line of sight between the meter and the mobile device within a 10-meter radius.

• Probe Care: Utilize the high-quality gold-plated probes for 600,000-count measurements to minimize contact resistance and ensure maximum accuracy.
