JUNIOR-BD

The JUNIOR-BD leaf clip adds measurements of photosynthetically active radiation, PAR, in μmol m^-2 s^-1 and leaf temperature as complementary information to fluorescence data. PAR is measured by a micro quantum sensor mounted parallel to the sample, and temperature is recorded by a Ni-CrNi thermocouple which touches the lower leaf surface.

Compared to its predecessor (JUNIOR-B), the JUNIOR-BD clip provides advanced digital features: the clip converts primary PAR and temperature signals into digital information and, thus, transfers signals without loss to the JUNIOR-PAM. Further, the calibration data of both sensors of the clip are stored on the clip’s flash memory and they are automatically used by the JUNIOR-PAM connected.

The JUNIOR-BD clip is only compatible with newer types of JUNIOR-PAM fluorometers. The predecessor leaf clip, however, is still available. When reordering a leaf clip, please provide serial number of your JUNIOR-PAM so that we can select the proper accessory for you.
