What specifically distinguishes the “C” variant of the UT890 series is its inclusion of a dedicated K-type thermocouple for high-range temperature measurement. This makes it an invaluable tool for testing the thermal performance of heat sinks, checking 3D printer extruders, or diagnosing air conditioning units. Furthermore, it boasts an absolutely massive capacitance testing range (up to 100mF), allowing you to test large power supply capacitors that lesser meters simply cannot read. Housed in UNI-T’s signature rugged, drop-resistant over-molding and featuring a highly unique “blown fuse” audible alarm, it is designed to keep both the meter and the operator completely safe during intense electrical work.

Key Features & Functional Advantages

• True RMS Measurement: Delivers highly accurate AC voltage and current readings on complex, non-sinusoidal electrical waveforms where standard meters would calculate the wrong values.

• Integrated Temperature Testing: Comes with a K-type thermocouple probe, allowing you to directly measure extreme physical temperatures from -40C all the way up to 1000C.

• Massive Capacitance Range: Capable of measuring up to 100mF (100,000F), making it incredibly useful for repairing audio amplifiers and heavy-duty motor start capacitors.

• Intelligent Fuse Alarm: Features a built-in safety warning system that audibly and visually alerts you if the internal protection fuses have blown, preventing you from chasing false diagnostic readings.

• High Current Capacity: Designed to safely handle up to 20 Amps of continuous current, significantly outperforming the standard 10-Amp limit found on most handheld meters.

Perfect For

• HVAC & Refrigeration Technicians: The absolute best choice for diagnosing air conditioning units, testing thermostat relays, and measuring refrigerant line temperatures.
