SLF flow air tightness tester is a gas tightness tester with flow detection method. The air tightness tester with flow sensor as the core is mainly used in the fields of air permeability detection, air flow detection, waterproof and ventilation test.
The SLF flow tightness tester uses air as the detection medium. Leak detection with gas is based on the fact that all media (gas) have small and low molecular weight and good permeability. Under certain pressure (positive or negative pressure), the leakage performance of the product is checked. Air tightness."
The principle of the flow tightness tester is: use the sum of the "leakage" of the product to be tested as the participation value to "leakage rate", or the "pressure drop" under the specified conditions, or the "flow rate of the gas within a certain period of time" "To determine the sealing of the product. The core component is a secondary sensor developed by a flow sensor and calculated by an algorithm to obtain a leak rate.
SLF air tightness detector, the test pressure can be automatically determined, the upper and lower limits of the flow rate are automatically determined, the air tightness detection speed is fast, the efficiency is high, and the power self-test is performed.
Hailim SLF flow air tightness detector comes with air filter adjustment and stability system, unique internal stability loop, enough to ensure the stability of air tightness detection and waterproof detection.
Multi-channel data storage function (convenient to record multiple product detection data separately), the core components are all imported, guarantee quality, and airtight leak detection accuracy, flow leak detector stability, multi-functional input and output interface.
