Gravity convection incubator LB-30CGI is equipped with an air jacket system for uniform temperature distribution, excellent thermal insulation and gentle air flow in the chamber. Microprocessor PID auto-tuning controller installed at the bottom of the chamber controls temperature, speed and flow. Safety tempered glass inner door prevents heat loss and provide clear sample visualization. Safety devices include ELB (elastic load balancing), self-diagnosis functions such as memory error, overheating, SSR and sensor short circuit for end user's safety.
