An analyzer may include a body housing having a first ID, a first measurement module having a second ID that is different from the first ID, the first measurement module being releasably attachable to the body housing, a first memory in the body housing, the first memory being configured to store the first ID, first setting data and first correction data, a second memory in the first measurement module, the second memory being configured to store the second ID, second setting data and second correction data, a first CPU in the body housing, the first CPU being configured to detect the first measurement module having the second ID, and a first data transmission unit in the body housing, the first data transmission unit being configured to transmit the first setting data and the first correction data to the second memory.

Analyzer

The invention relates to an infrared ray moisture meter which measures moisture of paper using absorption of infrared rays, and in which infrared rays being penetrated and scattered by the paper are sufficiently independent of whether the paper is thin or thick, in which sensitivity is high, in which attenuation of rays is small and error due to misalignment in the XY direction is small. Also, concurrently, in the invention, adverse influence due to quality of the paper is reduced by applying infrared rays which are absorbed by moisture, infrared rays which are absorbed by cellulose, and infrared rays which are not absorbed by moisture or cellulose, and by computing the value of moisture from signals detected from the application of the different infrared rays. In one embodiment a device is provided with a shielding plate having two mirrored surfaces disposed between the paper being measured and a lower one of a pair of reflectors.
