15、如：传感器0的温度在-196.5到-197.8度范围内跳动 ，就得把校准值设为正的11（即正1.1度）这时温度的跳动范围应在-195.4到-196.7度 按此方法校准另外泡在液氮里的传感器，然后取这几个泡在液氮里传感器的校准值的平均值设到另外的传感器校准值上。 Liquid nitrogen container control systemManualChengdu Shengjie Cryogenic Equipment Co., Ltd.This manual focuses on the function and use of liquid nitrogen biological con
