FNIRSI DSO152 portable mini oscilloscopeThe FNIRSI DSO152 is a compact oscilloscope designed for mobile service and educational work. Despite its pocket size (99 × 68.3 × 19.5 mm), it offers a full set of features, including 2.5MS/s sampling, 200kHz bandwidth, measurement up to ±400V, and automatic parameter setting. A built-in 1,000mAh battery, 2.8" display, measurements of 8 types of parameters and a software update function will make the FNIRSI DSO152 a versatile tool for field, workshop and laboratory use. The device is used in household appliance service, car repair, teaching and DIY projects.High precision measurementsThe FNIRSI DSO152 oscilloscope offers a true sampling rate of 2.5MS/s and a bandwidth of 200kHz, enabling precise recording of voltage signals up to ±400V. Such a solution works well for measurements in 220V installations, as well as for pulse or power circuit analysis. One-button measurement settings can be automatically selected, eliminating the need for manual calibration. This makes it easier for beginners and reduces setup time for quick diagnoses.Signal calibration and testThe built-in 1kHz rectangular signal source allows quick testing and calibration of the measurement probe, which guarantees repeatability and correctness of measurements without the need for additional equipment.Convenient operationIntuitive operation with responsive buttons and a slider for quick scrolling and changing settings. Navigation through the functions is done efficiently and without the need to reach for the manual. The device fits in the palm of your hand and weighs just 100 grams, making it easy to transport and allow use in hard-to-reach places. The integrated leg allows you to position the oscilloscope at a 90° angle and work hands-free. The oscilloscope features a USB-C port that supports both 5V/1A charging and software updates. This allows you to use universal cables and chargers.Included: FNIRSI DSO152 portable mini oscilloscope Probe with crocodile clamps Charging cable User manual Manufacturer FNIRSI Model DSO152 Sampling frequency 2.5MS/s Bandwidth 200kHz Vertical sensitivity 10mV/Div-20V/Div (stepped according to the 1-2-5 circuit) Voltage range X1: ±400V (Vpp: 800V)X10: ±40V (Vpp: 800V) Trigger method Auto/Normal/Single Coupling type AC/DC Display 2.8 inches / PPI: 320×240 USB charging 5V/1A Lithium battery capacity 1000 mAh Frequency 1kHz Filling factor 50% Dimensions 99×68.3×19.5 mm Weight 100 g
