Leak Detection Tools,Ultrasonic Leak Detector & Transmitter with Headphone Accessory Kit for Pipeline/tire/Refrigeration Equipment Leak Detection, Automotive Window Seal Inspection etc.
Features
- Located the leak location: Because the sound frequency of the leak port is different from other places, it quickly determine the leak port, suitable for all types of pressure or vacuum system gases.
- Check the degree of sealing: Adopt the advanced ultrasonic sensor technology to detect leaks of steam and liquid , detect the sealing degree of closed parts, such as cabins, car cockpits, refrigerators and containers.
- Two measurement methods: real-time detection that EM282-R detects leak port by the sound frequency; And non-real-time detection is that EM282-R capture the frequency signal from EM282-T. If there is gas in the pipe or tank, use real-time detection, or use non-real-time detection
- Adjustable sensitivity, frequency response: 40KHz±2KHz, adapt to various degrees of leakage, easy to detect and improve measurement accuracy.
- Ultrasonic testing, fast and accurate, simple to use, green and environmentally friendly. With headphones, indicator lights, beginners can also quickly learn to use.
