The Handyscope TP450 is a compact, USB-powered power quality analyzer designed for accurate and safe measurement of mains voltage. Engineered by TiePie Engineering, it features a fully galvanically isolated differential input that can handle up to ±450 V, making it ideal for direct connection to 110 V or 230 V mains power without requiring external probes or attenuators. With 16-bit resolution and sampling rates of up to 250 kSa/s (depending on the model), it delivers detailed and reliable waveform analysis across a wide frequency range.

Available in multiple configurations with up to 1 million samples of memory (XM models), the TP450 excels in long-term data logging, harmonic analysis, and power diagnostics. It functions as a versatile all-in-one instrument—oscilloscope, spectrum analyzer, multimeter, data logger, and protocol analyzer—when used with the included Multi Channel software for Windows 10/11.

Whether you’re a field technician, engineer, or educator, the TP450 offers professional-grade performance in a lightweight and portable form factor. It comes with measuring leads, probes, alligator clips, international mains adapters, and free software updates. Ideal for power quality monitoring, troubleshooting, and educational use.
