The Weiber growth chambers use a 2-step programmable digital PID controller for highly accurate and optimum working temperatures and programmable operation of the equipment. They also come equipped with an efficient cooling system comprising of hermetically sealed compressors and autoexchange dual evaporator for maintaining the desired temperature levels. These equipments use an air distribution plenum for maintaining a uniform air flow, ensuring adequate ventilation of plant surfaces and uniform temperature and humidity conditions within the chamber. They come equipped with active humidifiers to meet the higher humidity requirements of most of the potted plants. These humidifiers use SUS 316 pipe heaters and efficient motors for evaporation of water from the water reservoir. The digital ceramic device humidity sensors and digital PID humidity controller provides precise control of relative humidity within the chamber.
These growth chambers use a standard lighting system comprising of fluorescent and candescent lamps to provide a broad light spectrum for best plant growth. The equipments are fitted with a light meter comprising of movable sensor with flexible cable to allow continuous monitoring of illumination levels and light quantity. A photo period program control fitted with 24-hour timer provides efficient control of illuminance to allow definite hours of photoperiod for plant photosynthesis. These equipments are designed for automated operation and can also be remote operated for convenience. The programmable operation allows the user to set the operating parameters at defined set points, whereas the audio and visual alarms allow accurate monitoring of the equipment, preventing deviations from set points.
These growth chambers also come equipped with other safety features including an over-temperature protection feature, level monitor and power breaker for added safety. They provide an economical and energy efficient solution to the growth and maintenance of large sized plants and cultures on a laboratory scale and come equipped with product certifications and markings for quality and safety. These large capacity growth chambers also come equipped with sturdy castor wheels for easy movement.
