Device for inspecting a biological fluid

A device for inspecting a biological fluid, comprising:

• a channel through which the fluid flows;
• a first inspection module arranged in a first region of the channel;
• and
• a second inspection module arranged in a second region of the channel, wherein the device is configured to provide a quantity that is representative of an output of the second inspection module,
• wherein the first inspection module is configured to measure at least one electrical property of the fluid passing through the first region, the second inspection module is configured to measure at least one optical property of the fluid passing through the second region, and
• the inspection device further comprises a controller connected to the first inspection module and to the second inspection module and configured to control the second inspection module according to an output of the first inspection module,
• wherein the controller is configured to emit a control signal having a delay chosen relative to an output signal of the first inspection module, wherein the controller is configured to define the chosen delay as a function of distance between the first region and the second region, of at least one time property of the second inspection module, and of a speed of the fluid passing through the channel.
