The UNI-T UT890C is a professional-grade, 6000-count True RMS digital multimeter (DMM) designed for electricians, electronics technicians, and serious DIY enthusiasts. As part of UNI-T’s UT890 series, this feature-rich meter combines safety, accuracy, and versatility, making it suitable for a wide range of applications from industrial electrical work to mobile phone motherboard diagnostics.

The UT890C is distinguished from the UT890D+ primarily by its integrated temperature measurement function, which makes it particularly valuable for HVAC and refrigeration technicians. With a large, backlit LCD display, manual ranging, and an extensive set of measurement functions, it offers excellent value for money while maintaining the safety standards expected of a professional test instrument.

Key Features

True RMS (TRMS) Measurement
Provides accurate readings of AC voltage and current even when dealing with distorted sine waves from non-linear loads (e.g., motors, switching power supplies, inverters). This ensures reliable diagnostics in modern electrical environments.

6000-Count Large LCD with Backlight
The high-resolution 6000-count display allows for more detailed readings, while the 30-second backlight enables comfortable use in dimly lit workspaces, such as inside electrical panels or during field service.

Automatic Fuse Blown Detection & Overload Alarm
This intelligent meter actively detects and alerts the user to a blown fuse or an overload condition on the current ranges, helping to prevent measurement errors and ensuring safety.

NCV (Non-Contact Voltage) Detection
Rapidly identify live wires without touching them. The NCV function provides both audible and visual alarms, enabling quick and safe identification of live AC voltage presence.

High-Precision Temperature Measurement
Unique to the UT890C, this model includes a thermocouple probe for measuring temperatures from -40°C to 1000°C, essential for HVAC, refrigeration, and thermal diagnostics.

AC/DC Current Mode Memory
The meter remembers the last used current measurement mode (AC or DC) when the function dial is returned to the current position, streamlining workflows for technicians who frequently switch between tasks.

HFE Transistor Test
Includes a built-in socket and function for measuring the DC current gain (hFE) of bipolar transistors, a vital feature for electronics repair and troubleshooting.

Manual Ranging & Data Hold / REL
Gives the user full control to lock in a specific range or capture readings on the display. The REL (relative) mode allows nulling of lead resistance for precise low-resistance measurements.

MAX/MIN Recording
Records and displays the highest and lowest values during a measurement session, useful for monitoring signal fluctuations over time.

Intelligent Power Management
Low power consumption (approx. 1.8 mA) and an automatic power-off feature (after 15 minutes of inactivity) significantly extend battery life, rated for over 500 hours of continuous use.
