ZOYI ZT-225 25,000-Count True RMS Digital Multimeter
A high-resolution digital multimeter designed for precise bench measurements, electronics repair, electrical maintenance and dependable field diagnostics.
Precision Measurement for Bench and Field Work
The ZOYI ZT-225 is a high-precision True RMS digital multimeter developed for technicians, engineers and experienced DIY users who require detailed and dependable electrical measurements.
Its impressive 25,000-count high-resolution display provides finer measurement detail than a standard general-purpose meter, making the ZT-225 particularly useful for electronics servicing, laboratory testing, component evaluation and advanced fault finding.
Why True RMS matters: True RMS measurement improves accuracy when testing non-linear or distorted electrical signals commonly produced by LED drivers, switch-mode power supplies, inverters, chargers and other modern electronic equipment.
Core Measurement Functions
AC/DC Voltage
Measure voltage in electrical and electronic circuits.
AC/DC Current
Support for current testing during diagnostics and maintenance.
Resistance & Continuity
Check resistive components, wiring paths, cables and connections.
Capacitance
Evaluate capacitors during component testing and repair work.
Frequency & Duty Cycle
Useful for signal checks, control circuits and electronic troubleshooting.
Diode Testing
Quickly inspect diodes and semiconductor junctions.
Clear 25,000-Count Display
The large backlit LCD offers excellent visibility when working on busy benches, inside electrical panels or in poorly lit locations. Its high display resolution makes small changes in measured values easier to observe during detailed testing.
Automatic range selection helps the meter choose a suitable measurement range, supporting efficient operation without constant manual adjustment. The robust casing and practical control layout make the ZT-225 suitable for regular workshop and field use.
Measurement reminder: Always select the correct input terminals and measurement function before connecting the test leads. Observe the meter’s rated limits and use appropriate personal protective equipment when working on live electrical systems.
