UNI-T UT58B digital multimeter — 2000-count, 20A AC/DC, capacitance, temperature

The UNI-T UT58B is a reliable general-purpose digital multimeter suited for students, hobbyists, and technicians who need a versatile, easy-to-use instrument for everyday electrical measurements. With a 2000-count display, 20A AC/DC current range, capacitance measurement, K-type temperature probe input, and transistor (hFE) testing, it covers a wide range of tasks from basic voltage checks to component evaluation.

Key Specifications:

• Display: 2000-count LCD, update rate 2–3 times/second
• DC Voltage: 200mV / 2V / 20V / 200V / 1000V
• AC Voltage: 200V / 750V
• DC Current: 2mA / 20mA / 200mA / 20A
• AC Current: 20A
• Resistance: 200Ω / 2kΩ / 20kΩ / 200kΩ / 2MΩ / 20MΩ
• Capacitance: 2nF / 20nF / 200nF / 2μF / 20μF
• Temperature: −40°C – 1000°C (with included K-type thermocouple probe)
• Transistor (hFE) test: yes (NPN/PNP)
• Diode test: yes
• Continuity buzzer: yes
• Data hold: yes
• Auto power off: yes
• Overload protection: yes

Key Features:

• 20A AC/DC current measurement — handles high-current loads without an external shunt
• Capacitance measurement — test capacitors directly without a separate LCR meter
• K-type temperature probe included — measure temperatures up to 1000°C out of the box
• Transistor hFE test socket — quickly check NPN and PNP transistor gain
• Function symbols and test lead connection indication — on-screen guidance reduces wiring errors
• Overload protection — protects the meter from accidental misconnection
• Data hold — freeze the reading for easy logging in tight spaces
• Auto power off — extends battery life

Applications:

• General electrical and electronics troubleshooting
• Component testing (resistors, capacitors, diodes, transistors)
• AC/DC voltage and current measurement
• Temperature monitoring with K-type thermocouple
• Educational and lab use
• Home electrical maintenance
