Description
Product information
FNIRSI 2C53P 4.3" portable 3-in-1 touchscreen oscilloscope.
The FNIRSI 2C53P is a portable oscilloscope that combines three functions: a two-channel oscilloscope, a digital multimeter and a DDS generator. The device offers extensive functionality in a compact form. It features a 4.3-inch IPS touchscreen with 480 × 272 pixel resolution, which provides intuitive operation and free viewing of waveforms with zoom and pan capabilities. The oscilloscope offers a 50 MHz bandwidth, 250 MSa/s sampling rate and 12 switchable waveforms. This makes it ideal for measuring voltage, current, resistance, capacitance or temperature with precision up to 19999 readings.
Advanced signal analysis capabilities
The FNIRSI 2C53P enables professional signal analysis with functions such as FFT (fast Fourier transform), X-Y mode, cursor measurements, mathematical functions, and True RMS function. The oscilloscope offers three trigger modes (auto, normal, single), and with the "auto set" function, waveform calibration is done with a single button. In addition, a band-limiting function of up to 20 MHz is available, allowing accurate measurement of power supply interference at the millivolt level.
Multimeter with high precision and safety
The built-in multimeter supports measurements of AC/DC voltage, current, resistance, capacitance, diodes, continuity and temperature. 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. The dual ceramic fuses used 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. The FNIRSI 2C53P is equipped with a tempered glass screen, an adjustable stand (90°), a compact and impact-resistant housing, making it suitable not only in the workshop, but also in the field. The whole device supports up to 8 interface languages, including Chinese, English, Russian, Japanese, Spanish, Portuguese, German and Korean.
Ideal for precision measurement and analysis
The FNIRSI 2C53P oscilloscope is used for measuring 220V mains voltage, switching power supplies, power supply interference, pulse signals, as well as for analyzing audio signals. It is a versatile tool that will be perfect for both professional laboratory and hobbyist applications.
