Biosensor cartridges and test device therefor

A probe device for testing a sensor chip that detects a target material from an applied analysis specimen, has a reactant reacting specifically with the target material, and transmits a generated electrical signal, the probe device comprising:

• a lower housing configured to accommodate a circuit board of the sensor chip, the circuit board including a connection terminal configured to be electrically connected to an external test device;
• a middle housing coupled to the lower housing, the middle housing configured to have the sensor chip mounted thereon;
• a probe module including a plurality of probe pins for connecting a pad of the sensor chip to a connection pad of the circuit board;
• and
• an upper housing coupled to the middle housing, the upper housing including a guide area having a recessed portion that exposes a sensor area of the sensor chip,
• wherein the middle housing includes a plurality of pin openings which exposes the connection pad of the circuit board, and
• wherein some of the plurality of probe pins passes through the plurality of pin openings.
