PINTECH RT350M is a universal dual-range passive oscilloscope probe with DC~350MHz bandwidth, switchable 1X/10X attenuation via body toggle switch, complying with CAT II 600V safety voltage standard. It adopts precision voltage divider with ultra-low noise and high sensitivity, equipped with dual-side adjustable compensation capacitor to match analog & digital oscilloscopes with input capacitance of 10~35pF. The cable uses special low-temperature resistant material, maintaining flexibility and stable measurement at -10℃ in cold workshops and outdoor sites. Passive design requires no external power supply with universal standard BNC connector compatible with all brands of oscilloscopes from 100MHz to 350MHz. Supplied with complete insulated test accessories, it is widely used for medium & high frequency waveform debugging of switching power supplies, inverters, industrial control boards, home appliances, low-voltage automotive circuits and laboratory testing.
