Used LICOR 4200 #154274 for sale

LICOR 4200 is a laboratory instrument and accessory designed to provide accurate measurements of photosynthetic rates and light intensity with low maintenance. It is compatible with a variety of plant chamber designs, ranging from controlled environment rooms to open-top systems. The instrument comes with an on-board temperature, humidity and EC probe, allowing for easy monitoring of the environment. It features a reliable light source that can be set for red, blue, and far-red light. 4200 also has a built-in stomatal imaging system and a data storage capability. LICOR 4200 operates by computing the difference between the CO2 concentration leaving a leaf chamber and the CO2 concentration inside the leaf chamber. Light measurements are taken from a wide range of wavelengths, from 400 to 700 nanometers. The instrument has an adjustable voltage input, and the data can be read through a USB port or RS232 serial interface. 4200 can work in both continuous and intermittent exposure to light. When used in continuous mode, the light intensity is kept constant over a certain length of time. With an intermittent exposure, the light exposure can be changed in order to measure specific cellular functions. It also allows for inquiry-mode data acquisition so the user can react in real-time to the changing environment. LICOR 4200 is designed with an automatic calibration feature allowing for consistent measurements with very little preparation. The calibration feature accounts for temperature, light, and CO2 drift, as well as barometric pressure. It also reduces the risk of biofouling, which can lead to inaccurate data. The instrument also comes with a range of optional accessories. These accessories include different-sized leaf pucks, buffers, and a reference cell, as well as an aerosol sampler and a roving trace gas analysis system. 4200 is an excellent solution for laboratories looking for an accurate and reliable instrument for photosynthetic and light measurements. The built-in temperature, humidity and EC probes and the adjustable light intensity, together with the calibration feature make it an excellent choice for research in plant physiology and plant environment.
