Single-station portable suction-resistance tester

This system enables free selection of suction parameters—suction capacity, suction duration, suction interval, and suction speed—along with upper and lower limits for suction resistance to identify defective products. After setup, it measures suction resistance, counts cycles, and supports high-precision operation with easy use. Key functions include a reverse purging (reverse 吹扫) mode, segmented suction, selectable suction-curve modes, per-cycle suction-resistance measurement, and recording, st

This device enables free selection of suction parameters—including suction capacity, suction duration, suction interval, and suction speed—and allows setting upper and lower limits for suction resistance to identify defective products. After the suction parameters are configured, the system measures suction resistance, tracks the number of cycles, and operates with high precision and ease of use. Additional functions include a reverse purge feature, segmented suction capability, selectable suction-curve modes, per-cycle suction-resistance measurement, and recording, statistical analysis, and storage of cycle counts.
