Filter Integrity Tester (Filter Count Leak Detector)
SX-L310S high-efficiency air outlet leakage detector

Product Description：
The SX-L310S high-efficiency filter counting and leak detector is designed according to the requirements of ISO14633-3 B.6.3 and IEST-RP-CC034.2 specifications. It is a specialized instrument for scanning and detecting high-efficiency air vents in clean rooms (areas). It consists of three parts: an aerosol generator, a particle diluter, and a counting and leak detector (equipped with a handheld intelligent scanning probe).

The SX-L310S high-efficiency filter counting and leak detector uses the counting method to scan and detect leaks. The counting and leak detector, in conjunction with a particle counter, detects the upstream concentration of the filter, calculates the downstream leak point value based on the labeled efficiency of the filter, and compares the actual scan detection of the downstream leak point value of the high-efficiency air outlet with the calculated leak point value to achieve leak detection of the high-efficiency air outlet. Appendix B.6.3 of Part 3 of GB/T25915 "Clean Rooms and Related Controlled Environments" details the procedures for counting scanning leak detection. GB50591 "Code for Construction and Acceptance of Clean Rooms" recommends that the counting scanning method should be preferred for leak detection.

Performance advantages:

● Meet the requirements of domestic and international standards;
● Counting function: dynamic GMP, static GMP, ISO14644-1 level judgment, UCL automatic calculation;
● Automatic judgment of leakage point value, leakage alarm, leakage particle size tracking, and on-site printing;
● The upstream dust concentration is much lower than that of the photometer method, which causes little damage to the filter;
● High detection sensitivity, equally applicable for ultra efficient filter leakage detection;
● Built in large capacity lithium battery, capable of continuous operation for more than 4 hours;
● It is recommended to use DEHS aerosols for low detection costs.
Leak detection process:
Firstly, check the environment of the clean room;
Then: the first step is to generate dust upstream
Step 2 Upstream concentration measurement
Step 3: Manual scanning and detection
