FNIRSI 2C23T is a compact portable 3-in-1 oscilloscope that combines a dual-channel oscilloscope, a True RMS digital multimeter, and a signal generator in one device. With a color 2.8" display, intuitive controls, a 3000 mAh battery, and a rugged design, it’s ideal for electronics service, development, diagnostics, and field measurements.
Dual-channel oscilloscope for accurate signal analysis

Dual-channel oscilloscope for accurate signal analysis

The oscilloscope with 10 MHz bandwidth and a 50 MS/s sampling rate lets you view two channels simultaneously, use Auto, Normal, or Single triggering, and save waveform screenshots for further analysis.

True RMS multimeter with a wide measurement range

True RMS multimeter with a wide measurement range

The integrated digital multimeter measures voltage, current, resistance, capacitance, diodes, and continuity. Auto-ranging and True RMS measurement make work easier and improve accuracy in both everyday and more demanding situations.

Signal generator and rugged portable design

Signal generator and rugged portable design

The built-in generator offers sine, square, triangle, noise, DC, and other signal types. The compact build with a protective silicone case, a 3000 mAh battery, and USB-C charging is suitable for both the workshop and the field.

FNIRSI 2C23T provides broad measurement capabilities for both a professional workshop and mobile use. The oscilloscope with two independent channels, 10 MHz bandwidth, and a 50 MS/s sampling rate allows you to monitor waveforms, analyze pulses, check power-supply ripple, or test audio signals. Automatic setup, trigger modes, and the ability to save waveforms speed up work and make later evaluation easier.

The built-in multimeter can measure AC and DC voltage, current, resistance, capacitance, diodes, and continuity. True RMS technology and auto-ranging contribute to accurate results, while ceramic fuses increase operating safety. The signal generator function offers 7 waveform types with a frequency from 1 Hz to 2 MHz and an adjustable amplitude from 0.1 to 3.3 V.

The rugged ABS body with a silicone protective cover, a practical kickstand, silicone buttons, and USB-C charging make this instrument a reliable helper for everyday use. The package includes the oscilloscope, a 10× probe, an alligator-clip probe, multimeter probes, a charging cable, and a user manual.
