FNIRSI 2C53P portable 4.3-inch 3-in-1 touch screen oscilloscope.

The FNIRSI 2C53P is a portable oscilloscope that combines three functions: a dual-channel oscilloscope, a digital multimeter and a DDS generator. The device offers extensive functionality in a compact form. It has a 4.3-inch IPS touch screen with a resolution of 480 × 272 pixels, which allows intuitive operation and free viewing of waveforms with zoom and pan options. The oscilloscope offers a bandwidth of 50 MHz, a sampling rate of 250 MSa/s and 12 switchable waveforms. This makes it ideal for measuring voltage, current, resistance, capacitance or temperature with an accuracy of up to 19999 readings.

Advanced signal analysis capabilities

The FNIRSI 2C53P oscilloscope enables professional signal analysis with features such as FFT (Fast Fourier Transform), XY mode, cursor measurements, mathematical functions and True RMS function. The oscilloscope offers three trigger modes (auto, normal, single), and with the "auto-tune" function, waveform calibration is performed with a single button. In addition, a band-limiting function up to 20 MHz is available, which allows accurate measurement of power supply disturbances at the millivolt level.

Multimeter with high accuracy and safety

The built-in multimeter supports AC/DC voltage, current, resistance, capacitance, diode, conductivity and temperature measurements. The device offers extremely accurate measurements (up to 19999 readings) and allows you to store up to five measurement parameters, track changes in minimum and maximum values, and export data to a computer via the "USB Sharing" function. Dual ceramic fuses protect the device from current and voltage overloads, ensuring safe use.

Fast charging and robust design

The built-in lithium battery with a capacity of 4000 mAh ensures long operation of the device without frequent charging. FNIRSI 2C53P is equipped with a tempered glass screen, an adjustable stand (90°), a compact and shockproof housing, which makes it suitable not only in the workshop, but also in the field. The entire device supports up to 8 interface languages, including Chinese, English, Russian, Japanese, Spanish, Portuguese, German and Korean.

Ideal for precise measurements and analyses

The FNIRSI 2C53P oscilloscope is used to measure 220 V mains voltage, switching power supplies, power supply interference, pulse signals and for analyzing audio signals. It is a versatile tool that is ideal for both professional laboratory and hobbyist use.
