The FNIRSI DSO152 is a compact oscilloscope designed for mobile service and educational work. Despite its pocket size (99 x 68.3 x 19.5 mm), it offers a full range of features, including 2.5MS/s sampling, 200 kHz bandwidth, measurement up to ±400V and automatic parameter adjustment. The built-in 1000mAh battery, 2.8" display, 8 types of parameter measurement and software update function make the FNIRSI DSO152 a versatile tool for field, workshop and laboratory use. The device is used in home appliance service, car repair, education and DIY projects.
The FNIRSI DSO152 oscilloscope offers a true sampling rate of 2.5MS/s and a bandwidth of 200kHz, enabling accurate recording of voltage signals up to ±400V. Such a solution is well suited for measurements in 220V equipment and for analysis of pulse or power circuits. One-touch measurement settings are automatically selected, eliminating the need for manual calibration. This makes things easier for beginners and reduces setup time for quick diagnoses.
The built-in 1 kHz right-angle signal source enables quick testing and calibration of the measuring probe, which guarantees the repeatability and correctness of measurements without additional equipment.
Intuitive handling with sensitive buttons and slider for fast scrolling and quick adjustment of settings. Navigation between functions is done efficiently and without reaching for the manual. The device fits in the palm of your hand and weighs only 100 grams, so it can be easily transported and used in hard-to-reach places. The built-in foot allows you to position the oscilloscope at a 90° angle and work hands-free. The oscilloscope has a USB-C port that supports 5V/1A charging and software update. This allows the use of universal cables and chargers.
