1. A sterilisation monitoring device for a molecular diagnostics analyser, the sterilisation monitoring device comprising:
a sensor arranged in use to detect ultraviolet radiation; and
an analysis unit connected to the sensor, the analysis unit comprising:
an inverted active low pass filter and a comparator, the sensor being connected at an input to the active low pass filter and an output of the active low pass filter being connected to an input of the comparator, the comparator being a voltage comparator and comprising a potential divider, an op-amp to which the potential divider and the output of the active low pass filter are connected, a pull-up resistor to which an output of the op-amp is connected, and an output to which the output of the op-amp and the pull-up resistor are connected, wherein
the analysis unit is arranged in use to issue a signal from the output of the comparator when the ultraviolet radiation level incident on the sensor is lower than a threshold level.
