The AR66L3Q33 growth chamber is designed for growth of Arabidopsis, spinach and low light plant growth. SciWhite with red LEDs are dimmable from 10-100% output with up to 360 µmoles/m2/s irradiance @ 6". IntellusUltra controller, touchscreen, CO2 control approx. 150-5000 ppm. Interior/exterior of smooth white galvanized steel with foamed-in-place non-CFC insulation and stainless-steel floor for corrosion resistance. Air circulation inside chamber is from a specifically designed adjustable air diffuser. Six solid stainless steel shelves adjustable in ½” increments. Self-contained air-cooled condensing unit with hot gas bypass system for continuous compressor operation extends life, ensuring precise temperature control by alternately cycling refrigerant and hot gas to coil; also prolongs life of compressor, and eliminates risk of ice build up in coil. Top mounted refrigeration system allows easy access for maintenance/ cleaning. Contact sales@percival-scientific.com for more options.
