OS1p Ultra Compact Chlorophyll Fluorometer An ultra compact, battery portable system designed for plant stress field research Ultra compact Weighs only 1.4kg Plant stress tests including Yield Y(II) Accurate and reliable experimental data Touch screen, colour, graphic display Plant stress research tool Chlorophyll fluorescence is a proven optical based technique for measuring plant stress. This is achieved by assessing a plant’s ability to utilise available sunlight in the photosynthesis process. Most types of plant stress can be measured in this way. The OS1p is the most portable, accurate and easy to use research chlorophyll fluorometer yet. Incorporating the latest fluorescence technology and user interface features, the OS1p sets a new benchmark for plant stress experimentation. The OS1p employs the proven pulse modulation fluorescence technique, where a rapidly pulsing excitation light is used to induce a corresponding pulsed fluorescence emission. This fluorescence is measured at a longer wavelength than the excitation light. This fluorescence intensity is plotted against time in a variety of experimental protocols. The sophisticated detection system distinguishes between the pulsed response and the non-pulsed light, allowing both ambient light and dark adapted experiments to be performed. The OS1p can perform the most commonly used and widely respected fluorescence tests such as Fv/Fm, Photosynthetic Yield Y(II), ETR, NPQ and rapid light curve. The new Multi-flash test ensures reliable data even at high saturation light levels. Truly field portable Weighing just 1.4kg, this robust, battery portable system offers up to 12 hours of continuous operation from a single charge.

Large integral data storage Data can either be stored in a large 1Gb internal memory, capable of storing thousands of test data sets and traces, or on removable SD memory cards. Once back in the laboratory, data is quickly and easily transferred to a PC via USB or directly from the SD cards. A wide variety of plant stresses can be quickly and easily analysed using the OS1p. The OS1p has been designed with a high degree of automation. Full programming and operation is achieved by a series of menus on a large backlit, colour, touch sensitive screen. The OS1p is supplied, as standard, with an open...

The most popular stress tests The OS1p provides researchers with the most widely used fluorescence test protocols, making it the ideal choice for the routine and fast testing of plant stresses on both algae and higher plants. Fv/Fm: Photochemical Efficiency: Quantum Photosynthetic Yield Y(II): The most widely used fluorescence test requires pre-darkening of the leaf. The OS1p optimises Fv/Fm measurements by firstly automatically setting the modulated light source. Then secondly by providing a far red light option to ensure full oxidation of PSII prior to test. Light adapted test, the test most...
