Auxiliary detection device for biosafety cabinet filter

The utility model discloses an auxiliary detection device for a biosafety cabinet filter. Wherein the two longitudinal guide rails are arranged in parallel, the cross beam is supported on the two longitudinal guide rails and can slide along the longitudinal guide rails, the cross beam is perpendicular to the longitudinal guide rails, a vertically-arranged photometer fixing seat is arranged on theupper side of the cross beam, and the photometer fixing seat can slide in the length direction of the cross beam. The integrity of leak detection of the high-efficiency filter of the biosafety cabinetcan be improved, the detection precision and the detection efficiency are improved, the labor intensity of operators is reduced, and misoperation is avoided. 本实用新型公开了一种生物安全柜过滤器辅助检测装置，包括两个平行设置的纵向导轨，以及支撑在两个所述纵向导轨上并能够沿纵向导轨滑动的横梁，所述横梁与纵向导轨相互垂直，横梁上侧具有竖直设置的光度计固定座，光度计固定座能够沿横梁长度方向滑动。可提高生物安全柜高效过滤器检漏检测的完整性，即提高检测精度和检测效率，同时降低操作人员劳动强度和避免操作失误。
