TR9318A can measure DC voltages up to 18KV and AC voltages up to 12KV; its 200MΩ input-impedance high-voltage probe can be connected directly to an oscilloscope for measurement and is suitable for high-voltage ground-referenced voltage measurement.
TR9318A uses an environmentally benign silicone resin insulating medium, which improves insulation performance, prevents internal components from oxidizing during high-voltage measurement, and extends service life.
Product Features:
• Maximum measurement voltage: 18KV DC+ACpeak
• Bandwidth up to 100MHz
• Input impedance 200MΩ
• Fixed attenuation ratio 1000:1, Read Out
• With an impedance matching adapter, it can be connected to a multimeter for use
