Information on ambient light and temperature conditions is indispensable for field investigation. Therefore, we have devised the leaf-clip 2030-B which measures by a mini-quantum sensor the photosynthetically active radiation (PAR) impinging on the leaf under investigation. In addition, the 2030-B leaf-clip records the leaf temperature with a NiCr-Ni thermocouple.
To facilitate studies under field conditions, fluorescence measurements can be triggered by pushing the control button of the leaf-clip holder 2030-B. A tripod (ST-2101A) is available for positioning of the leaf-clip 2030-B but also the mini quantum/temperature-sensor 2060-M or the Arabidopsis leaf clip 2060-B.
