The PeakTech 1094 two-pole voltage tester is a reliable and practical tool for measuring voltages up to 400 V. It uses LED indicators to display voltage levels at 12 V, 24 V, 50 V, 120 V, 240 V, and 400 V. The device supports both AC and DC voltage measurements and automatically detects and displays polarity when measuring DC voltages – no manual switching between AC and DC is required.
This tester operates without batteries, ensuring it is always ready for use, even after extended periods of inactivity. With its IP54 protection rating, the PeakTech 1094 is robust and resistant to dust and splashing water, making it suitable for use in both indoor and outdoor environments.

Specially developed for the education and hobby sector, this fully-fledged digital storage oscilloscope offers the best possible price/performance ratio without having to compromise on functionality or technical features. Whether Autoset and Autoscale, mathematical measurement functions, FFT, Cursor or XY mode and even a zoom function, all standard market functions are already integrated in this series.
The data storage of the waveforms is either internal with memory for 16 waveforms or external on a USB memory in TXT, CSV or BIN format, which can be read out with the included software. Configurations can also be saved internally or screenshots of the display can be saved externally.
The display of the waveforms can be achieved quickly and user-friendly through the Autoset function, via AutoScale the measured waveforms can be displayed even more precisely as required, whereby these settings can of course also be carried out completely manually via the key control.
Features
2-channel oscilloscope with 100 MHz analogue bandwidth at max. 1 GS/s sampling rate
17.5 cm (7") TFT colour display with 800 x 480 pixels
USB device connection for real-time data transmission
