New sensor solutions can only be achieved through new technologies. In order to remain successful, you have to reinvent yourself a little bit more every day. We take on this challenge every day. We at Picosens are innovative in the field of measuring technology, sensor technology and electronics development. New challenges in sensor technology allow us to develop new technologies – together with our customers when requested.

We realize complex applications and innovative high-class solutions. Our business activities range from the idea to the concept phase, patenting, development through to prototype construction and small series production. We are already investing in the ideas, technologies and products of tomorrow with a future-oriented vision. With the following solutions we achieve the unreachable.

High Impedance-Probe

Sensor technologies with a power consumption of less than 200nA at 3V are no longer a rarity. This is where developers with conventional oscilloscope probes reach their limits. In particular, a probe the measured values significantly falsified by its internal resistance, which is usually between 2 and 10 MΩ.

Unfortunately, “high-impedance” probes are hard to find in the market. That´s the reason for a difficult order and a high price.

Therefore, PicoSearch has developed an extremely high-impedance active probe for general laboratory work. With a load current consumption of less than 0.3pA (0 – 5V) it does not load the circuit during the measuring process.

Benefits of this technology:

  • Active probe with low load due to high input impedance > 20 Tera-Ohm
  • Universal probe with USB voltage connection
  • Low load current consumption < 0,3 pA
