FNIRSI 2C23T / 2C53T Handheld Digital Oscilloscope Multimeter Signal Generator

About this deal

The FNIRSI 2C23T and 2C53T are compact 3-in-1 dual-channel digital oscilloscopes aimed at professionals, students, and hobbyists in maintenance, development, and education, combining an oscilloscope, multimeter, and signal generator into a single handheld unit. The 2C23T offers a 10 MHz bandwidth and 50 MS/s sampling rate with a 4-digit 10,000-count true RMS multimeter, while the 2C53T steps up to 50 MHz bandwidth and 250 MS/s sampling, with a 4.5-digit 19,999-count true RMS multimeter and a signal generator capable of 13 waveform types up to 50 kHz. Both models use an FPGA plus MCU/ARM plus ADC architecture with built-in high-voltage protection supporting peak measurements up to plus or minus 400 V. Each model features a 2.8-inch 320x240 HD display and a 3,000 mAh rechargeable battery providing up to 6 hours of use. The 2C53T is an upgraded version of the 2C23T, adding math operations, cursor measurement, persistence mode, and XY mode. Waveform screenshots can be saved with one click and exported to a PC via Type-C for further analysis, making either model a practical all-in-one tool for bench and field use.
