| 摘要 |
The invention relates to a probe unit (1) having a probe housing (2), a probe electrode (3) that is rod-like, at least in some sections, an additional electrode (4), that surrounds the probe electrode (3) coaxially, at least in some sections, and is isolated from the probe electrode (3) by electrical insulation (5), a first fixing means (8), by means of which the additional electrode (4) is fixed in the probe housing (2), a contact-making module (6), which can be fitted to a rod-like section of the probe electrode (3) that is arranged in the probe housing (2), and which has a flexible printed circuit board (7) having at least one first conductor track (72) for making electrical contact with the probe electrode (3) and at least one second conductor track (75) for making electrical contact with the additional electrode (4), and having a second fixing means (9) for fixing the contact-making module (6) to the probe electrode (3). |
