TR9340A can measure up to 39 kV DC and 27 kV AC voltage, with 900 MΩ input impedance and low loading effect,
and its 50 MHz high bandwidth enables capturing fast, high-voltage signals.
The high-voltage probe can be connected to an oscilloscope for direct measurement, suitable for measuring high-voltage ground-referenced voltages.
An optional adapter also allows voltage values to be measured on a digital multimeter.
The TR9340A body is filled with inert gas, which improves insulation performance, ensures internal components do not oxidize while measuring high voltage, and extends service life.
Product Features:
• Maximum measurement voltage: 39 kV DC+ACpeak
• Bandwidth up to 50 MHz
• Input impedance 900 MΩ
• Fixed attenuation ratio 1000:1
• Can be connected to a multimeter with an impedance matching adapter
• Ultra-low noise
