DUAL-H90

90 Degree Measuring Head Holder wavelength chlorophyll fluorescence with a DUAL-PAM-100 system, or assessment of epidermal UV screening with a MULTI-COLOR-PAM fluorometer. Consisting of a right angle bracket made of black anodized aluminium, with metal rod for attaching the DUAL-H90 to a laboratory stand, each bracket arm has a special adapter to position a measuring head. Including a laboratory scissor jack with non-fluorescent rubber foam mat. Notes: Recording short and long wavelength chlorophyll fluorescence from leaves requires blue measuring light (DUAL-DB) and a DUAL-DPD measuring head; for Fo’ measurements, order a DUAL-DB Head in which far red LEDs replace the blue actinic LEDs. Measurements of epidermal UV screening requires a special MCP-E Head equipped with a UV-A LED.
