Jual JUNIOR-PAM Teaching Chlorophyll Fluorometer

Pulse-amplitude modulated (PAM) chlorophyll fluorometry in combination with saturating pulse analysis of fluorescence quenching is now a standard technique to assess plant photosynthesis. The JUNIOR-PAM fluorometer is a miniaturized instrument capable to carry out the full range of saturation pulse analysis of photosystem II. A small box of 11.5 x 6.5 x 3.0 cm contains all optical and electronic components. The fluorometer is connected to the sample via a 50 cm long single plastic fiber with 1.5 mm diameter. The JUNIOR-PAM employs the same blue (460 nm) power LED for pulse modulated fluorescence excitation, actinic illumination and saturating pulses. Also, the fluorometer features a far-red LED for selective excitation of PS I and determination of the Fo’ level fluorescence. Two different types of leaf-clips are provided, a 60° clip for measurements in ambient light and a magnetic leaf clip for Fo-Fm and Fv/Fm measurements. An optional monitoring leaf-clip is available to measure ambient light intensity (PAR, μmol m-2 s-1) at leaf level and leaf temperature (see Accessories).
