Air Pressure Seal Tester — ToronFT™ APS
ToronFT™ APS Air Pressure Seal Tester is a versatile pneumatic testing instrument designed for the performance testing of pressure-bearing products across a wide range of industrial and fire protection applications. Capable of evaluating air sealing performance, gas pressure resistance, gas leakage detection, and gas pressure resistance bursting tests, the ToronFT™ APS serves as a comprehensive air pressure qualification platform for valves, pipe fittings, pressure vessels, gas cylinders, and related pressure-containing components.
With a pressure range of 0–20 MPa (expandable to higher pressures upon request), compatibility with air, nitrogen, helium, and other gas media, a pressure measurement accuracy of ±0.5% F.S., and a pressure control accuracy of ±1% F.S., the ToronFT™ APS air pressure seal tester provides the measurement precision and operational flexibility demanded by both production quality assurance and certification testing programs.

Theory and Method
Air pressure seal testing pressurizes the test specimen to the specified test pressure using a gaseous medium (air, nitrogen, helium, or other specified gas) and evaluates whether the specimen maintains pressure integrity — showing no measurable leakage — over the required hold duration. The ToronFT™ APS applies the test pressure through the specimen connection interface and monitors pressure using precision transducers with ±0.5% F.S. accuracy throughout the test hold period. Gas pressure resistance testing applies pressure incrementally to the burst or proof pressure level, verifying structural integrity under over-pressure conditions.
Gas leakage detection uses sensitive pressure decay measurement — any drop in the monitored pressure during the hold period indicates leakage from the specimen. The precision timing system (0–999 h range) ensures that any standard-specified hold duration can be accurately executed, and the expandable test station design allows the instrument to grow from one station to multiple stations as throughput requirements increase.
