FNIRSI 2C53T is a practical portable 3-in-1 measuring instrument that combines a 50 MHz dual-channel oscilloscope, a digital multimeter, and a signal generator up to 50 kHz. Thanks to the color display, 250 MSa/s sampling, rugged design, and a 3000 mAh rechargeable battery, it is ideal for service work, electronics development, diagnostics, and field measurements.

FNIRSI 2C53T brings together functions that would normally require several separate instruments. The oscilloscope with two independent channels offers an analog bandwidth of 50 MHz, 250 MSa/s sampling, and Y-T, Rolling, and X-Y display modes for convenient analysis of waveforms, PWM signals, power-supply ripple, or phase relationships. The AUTO function sets the range and triggering with one button, making measurements fast without lengthy configuration.

The built-in high-resolution multimeter enables measurement of DC and AC voltage and current, resistance, capacitance, temperature, diodes, and continuity. The instrument is equipped with overload protection, dual ceramic fuses, and meets the CAT II 300 V safety category, increasing safety during everyday work.

For testing and electronics development, a signal generator is also available with a frequency from 1 Hz to 50 kHz and adjustable amplitude. The rugged ABS housing with silicone elements, a fold-out stand, USB-C charging, and a 3000 mAh battery ensure comfortable use in the lab, workshop, and in the field. The package includes rich accessories including probes, test leads, and a carry bag.
